Inspection and Audit The Company shall be permitted but not obligated to inspect the Named Insured's property and operations at any time.

The Company may examine and audit the Named Insured's books and records at any time during the policy period and extensions thereof and within three years after the final termination of this policy, as far as they relate to the subject ma'tter of this insurance. 3. Financial Responsibility Laws When this policy is certified as proof of financial responsibility for the future under the provisions of any motor vehicle financial responsibility law, such insurance as is afforded by this policy for bodily injury liability or for property damage liability shall comply with the provisions of such law to the extent .of the coverage and limits of liability required by such law. The Insured agrees to reimburse the Company for any payment made by the Company which it would not have been obligated to make under the terms of this policy except for the agreement contained in this paragraph. 4. Insured's Duties in the Event of Occurrence, Claim or Suit (a) In the event of an occurrence, written notice containing particulars sufficient to identify the Insured and also reasonably obtainable information with respect to the time, place and circumstances thereof, and the names and addresses of the injured and of available witnesses, shall be given by or for the Insured to the Company or It any of its authorized agents as soon as practicable.

Other Insurance The insurance afforded by this policy is primary insurance, except when stated to apply in excess of or contingent upon the absence of other insurance. When this insurance is primary and the Insured has other insurance which is stated to be applicable to the loss on an excess or contingent basis, the amount of the Company's liability under this policy shall not be reduced by the existence of such other insurance. When both this insurance and other insurance apply to the loss on the same basis, whether primary, excess or contingent, the Company shall not be liable under this policy for a greater proportion of the loss than that stated in the applicable contribution provision below: (a) Contribution by Equal Shares.

Assignment Assignment of interest under this policy shall not bind the Company until its consent is endorsed hereon; if, however, the Named Insured shall die, such insurance as is afforded by this policy shall apply (1) to the Named Insured's legal representative, as the Named Insured, but only while acting within the scope of his duties as such, and (2) with respect to the property of the Named Insured, to the person having proper temporary custody thereof, as Insured, but only until the appointment and qualification of the legal representative. 10.

The work, from its commencement to completion, shall be under the exclu- sive charge and control of the Contractor and all risk in connection therewith shall be borne by the Contractor. The Owner or Owner's Representatives will not be responsible for the acts or omissions of the Contractor, or any subcontractors, or any of his agents or employees, or_any other persons performing any of the work.

CONTRACTOR'S UNDERSTANDING It is understood and agreed that the Contractor has, by careful examina- tion, satisfied himself as to the nature and location of the work, the confir- mation of the ground, the character, quality and quantity of materials to be encountered, the character of equipment and facilities needed preliminary to and during the prosecution of the work, and the general and local conditions, and all other matters which in any way effect the work under this contract. No verbal agreement or conversation with any officer, agent, or employee of the Owner, either before or after the execution of this contract, shall effect or modify any of the terms or obligations herein contained. 18. CHARACTER OF WORKERS The Contractor agrees to employ only orderly and competent workers skill- ful in the performance in the type of work required under this contract, to do the work; and agrees that whenever the Owner's Representative shall inform him in writing that any worker or workers on the work, are, in his opinion, in- competent, unfaithful, or disorderly, such worker or workers shall be discharged from the work and shall not again be employed on the work without the Owner's Representative's written consent. 19.

Contractor shall ascertain the scope of any observation which may be contemplated by Owner or Owner's Representative and shall give ample notice as to the time each part of the work will be ready for such observation. Owner or Owner's Representative may -reject any work found to be defective or not in accordance with the con- II-5 tract documents, regardless of the stage of its completion or the time or ! place of discovery of such errors, and regardless of whether Owner's Observer has previously accepted the work through oversight or otherwise. If any work should be'coveredwithout approval or consent of the Owner, it must, if requested by Owner or Owr:er's Representative be uncovered for examination at Contractor's expense. In the event that any part of the work is being fabricated or manu- factured at a location where it is not convenient for N-ner or Owner's Representa- tive go make observations of such work or require testing of said work, then in such event Owner or Owner's Representative may require Contractor to fur- nish Owner or Owner's Representative certificates of inspection, testing or approval made by persons competent to perform such tasks at the location where that part of the work is being manufactured or fabricated.

The cost of all such inspections, tests, and approvals shall be borne by the Contractor unless otherwise provided herein. Any work which fails to meet the requirements of any such tests, inspections or approval, and any work which meets the requirements of any such tests or approval but does not meet the requirements of the contract documents shall be considered defective. Such defective work shall be corrected at the Contractor's expense. Neither observations by the Owner or Owner's Representative, nor inspec- tions,. tests, or approvals made by Owner, Owner's Representative, or other persons authorized under this agreement to make such inspections, tests, or approvals, shall relieve the Contractor from his obligation to perform the work in accordance with the requirements of the contract documents. 22.

It is further agreed that any remedial action contemplated as hereinabove set forth shall be at Contractor's expense. 23. CHANGES AND ALTERATIONS The Contractor further agrees that the Owner may make such changes and alterations as the Owner may see fit, in the line, grade, form, dimensions, plans or materials for the work herein contemplated, or any part thereof, II-6 either before or after the beginning of -the construction, without affecting j. the validity of this contract and the accompanying bond. If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the basis for a claim for damages, or antici- pated profits on the work that may be dispensed with. If they increase the amount of work, and the increased work can fairly be classified under the specifications, such increase shall be paid according to the quantity actually done and at the unit price established for such work under this contract; otherwise such additional work shall be paid for as provided under Extra Work. In case the Owner shall make such changes or alterations as shall make useless any work already done or material already furnished or used in said work, then the Owner shall recompense the Contractor for any material or labor so used, and for any actual loss occasioned by such change, due to actual expenses in- curred in preparation for the work as originally planned. 24. EXTRA WORK The term "extra work" as used in this contract shall be understood to mean and include all work that may be required by the Owner or Owner's Repre- sentative to be done by the Contractor to accomplish any change, alteration or addition to the work as shown on the plans and specifications or contract documents and not covered by Contractor's proposal, except as provided under Changes and Alterations herein. . It is agreed that the Contractor shall perform all extra work under the direction of the Owner's Representative when presented with a written work order signed by the Owner's Representative, subject, however, to the right of the Contractor to require written confirmation of such extra work order by the Owner.

In the event said extra work be performed and paid for under Method (C), then the provisions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost of all workmen, such as foremen, time- keepers, mechanics and laborers, and materials, supplies, teams, trucks, rentals on machinery and equipment, for the time actually employed or used on such extra work, plus actual transportation charges necessarily incurred, together with all expenses incurred directly on account of such extra work, including Social Security, Old Age Benefits, Maintenance Bonds, Public Lia- bility and Property Damage and Workmen's Compensation and all other insurances as may be required by law or ordinances or directed by'the Owner or Owner's' Representative, or by them agreed to. Owner's Representative may direct the form in which accounts of'the actual field cost shall be kept and records of these accounts shall be made available to the Owner's Representative. The m II-7 Owner's Representative may also specify in writing, before the work commences, the method of doing the work and the type and kind of machinery and equipment to be used; otherwise, these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equip- ment shall be determined by using 100Y, unless otherwise specified, of the latest -Schedule of Equipment and Ownership Expenses adopted by the Associated General Contractors of America. Where practical, the terms and prices for the use of machinery and equipment shall be incorporated in the written extra work order. The fifteen per cent (15i) of the actual field cost to be paid to Contractor shall cover and compensate him for his profit, overhead, general superintendence, and field office expense, and all other elements of cost and expense not embraced within the actual field cost as herein defined, 'save that where the Contractor's Cam2 or Field Office must be maintained primarily on account of such Extra Work, then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for extra work of any kind will be allowed unless ordered in writing by the Owner's Representative. In case any orders or instructions appear to the Contractor to_involve extra work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the Owner's Representative for a written order authorizing such extra work. Should a difference of opinion arise as to what does or does not constitute extra work, or as to the payment therefor, and the Owner's Repre- sentative.insists upon its performance, the Contractor shall proceed with -the work after making written request for written order and shall keep adequate and accurate account of the actual field cost thereof, as provided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to arbitration as herein below provided. 25. DISCREPANCIES AND OMISSIONS It is further agreed that it is the intent of this contract that all work described in the proposal, the specifications, plans and other contract docu- ments, is to be done for the prices quoted by the Contractor and that such price shall include all appurtenances necessary to complete the work in ac- cordance with the intent of these contract documents as interpreted by Owner's Representative. If the Contractor finds any discrepancies or omissions in these plans, specifications, or contract documents, he should notify the R Owner's Representative and obtain a clarification before the bids are received, and if no such request is received by the Owner's Representative prior to the opening of bids, then it shall be considered that the Contractor fully under- stands the work to be included and has provided sufficient sums in his pro- posal to complete the work in accordance with these plans and specifications. It is further understood that any request for clarification must be submitted no later than five days prior to the opening of bids. 26.

Before final payment is made, Contractor shall satisfy Owner, by affidavit II-14 or otherwise, that there are no outstanding liens against Owner's premises by reason of any work under the contract.

FINAL PAYMENT Upon the issuance of the certificate of completion, the Owner's Repre- sentative shall proceed to make final measurement and prepare a final state- ment of the value of all work performed and materials furnished under the terms of the agreement, and shall certify same to the Owner, who shall pay to the Contractor on or before the 31st day after the date of certificate of completion, the balance due Contractor under the terms of this agreement, provided he has fully performed his contractual obligations under the terms of this contract; and said payment shall become due in any event upon said per- formance by the Contractor. Neither the certificate of acceptance nor the final payment, nor any provisions in the contract documents shall relieve the Contractor of the obligation for fulfillment of any warranty which may be _ i required in the special cenditior►s (if any) of this contract or required in the specifications made a part of this contract. 44. CORRECTION OF WORK BEFORE FINAL PAYMENT FOR WORK Contractor shall promptly remove from Owner's premises all materials con- demned by the Owner's Representative on account of failure to conform to the contract, whether actually incorporated in the work or not, and Contractor shall at his own expense promptly replace such condemned materials with other = materials conforming to the requirements of the contract. Contractor shall also bear the expense of restoring all wor'; of other contractors damaged by any such removal or replacement. If Contractor does not remove and replace any such condemned work within a reasonable time after a written notice by the Owner or the Owner's Representative, Owner may remove and replace it at Con -tractor's expense. 45. CORRECTION OF WORK AFTER FINAL PAYMENT Neither the final payment nor certificate nor any. provision in this contract shall relieve the Contractor of responsibility for faulty materials or workmanship, and he shall remedy any defects due thereto and pay for any damage to other work resulting therefrom, which shall appear within a period of one (1)'.year frcm the date of substantial completion. The Owner or the Owner's Representative shall give notice of observed defects with reasonable promptness. 46. PAYMENT WITHHELD • The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such,extent as may be necessary to protect himself from loss on account of: (a) Defective work not remedied. - (b) Claims filed or reasonable evidence indicating possible filing of claims. (c) Failure of the Contractor to make payments promptly to subcontractors or for material or labor. (d) Damage to another contractor. When the above grounds are removed, or the Contractor provides a surety bond satisfactory to the Owner, which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them. t 47. TIME OF FILING CLAIMS It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Owner's Representative within fifteen (15) days after the Owner's Repre- sentative has given any directions, order or instruction to which the Contractor desires to take exception. The Owner's Representative shall reply to such written exceptions by the Contractor and render his final decision in writing. In case the Contractor should appeal from the decision of the Owner's Repra- sentative, any demand for arbitration shall be filed with the Owner's Repre- sentative and the Owner in writing within ten (10) days after the date of delivery to Contractor of the final decision of the Owner's Representative. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claim by either party, except where noted otherwise in the contract documents. 48. ARBITRATION All questions of dispute under this agreement shall be submitted to arbi- tration at the request of either party to the dispute. The parties may agree upon one arbitrator, otherwise, there shall be three;'one named in writing by each.party and the third chosen by the two arbiters selected; or if the arbiters fail to.select a third within ten (10) days, he shall be chosen by the District Judge, 72nd Judicial District of Texas. Each arbiter shall be a resident of the City of Lubbock. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the Owner's Representative shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the Owner's Representative shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take Ex Parte Proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract, unless either or both parties shall appeal within ten (10) days from date of the award by the arbiters, and it is hereby agreed that each party shall have the right of appeal and all proceedings shall be according to and governed by Arbitration Statutes of Texas, being _ Article 224, et seq., Vernon's Annotated Civil Statutes. THE DECISION OF THE ARBITERS UPON ANY QUESTION SUBMITTED TO ARBITRATION UNbER THIS CONTRACT SHALL BE A CONDITION PRECEDENT TO ANY RIGHT OF LEGAL ACTION. The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation, unless otherwise pro- vided by agreement, and shall assess the costs and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writing and shall not be open to objection on account of the form of proceedings or award. II-17 J, �.. In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after written notification from the Owner or the Owner's Representative, or if the Contractor fails to comply with the orders of the Owner's Representative, when such orders are consistent with this contract, this Agreement, or the Specifications hereto attached, then the Surety on the bond shall be notified in writing and directed to complete the work and a copy of said notice shall be delivered to the Contractor. After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under the contract for work, may be held for use on the work by the Owner or the Surety of the Contractor, or another contractor, in completion of the work; and the Contractor shall not receive any rental or credit therefore (except when used in connection with Extra Work, kffiere credit shall be allowed as provided for under paragraph 24 of this contract); it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. In case the Surety should fail to com::,ance compliance with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (a) The Owner may employ such force of men and use of machinery, 1, equipment, tools, materials and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said Contractor, and the expense so charged shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said Contractor, then the Contractor and/or his Surety shall pay the amount of such excess to the Owner; or (b) The Owner, under sealed bids, after notice published as required by law, at least twice in a newspaper having a general circulation in the County of location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the Contractor and the Surety shall be and remain bound therefore. However, should the cost to complete any such new contract prove to be less than that which would have been the cost to complete the wcrk under this contract, the Con- tractor or his Surety shall be credited therewith. When the work shall have been substantially completed, the Con- tractor and his Surety shall be so notified and certificates of completion and acceptance, as provided in paragraph 42 hereinabove set forth, shall be issued. A complete itemized statement of the contract accounts, certified to be the Owner's Representative as being correct shall then be prepared and delivered to Contractor and his Surety, whereon the Contractor or his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement within 31. days after the date of certificate of completion. In the event the statement of accounts shows that the cost to com- plete the work is less than that which would have been -the cost to the Owner had the work beencompletedby the Contractor under the terms of this contract, or when the Contractor and/or his Surety shall pay the balance shown to be due by them to the Owner, then all machinery, equip- ment, tools, materials or supplies left on the site of the work shall be turned over to the Contractor and/or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor and/or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools,.materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract; provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the 'Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any ma:ninery, equipment, tools, materials, or supplies which remain on the jobsite and belong to persons other than the Con- tractor or his Surety, to their proper owners. 50. ABANDONMENT BY OWNER In case the Owner shall fail to comply with the terms of this contract, and should fail or refuse to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools, and equipment, and all materials on the ground that have not been included in payments to the Contractor and have not been incorporated into the work. Thereupon, the Owner's Representative shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor at the prices stated in the attached proposal, the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion, and which cannot be utilized. The Owner's Representative shall II-19 then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agreement, and shall 'certify same to the Owner who shall pay to the Contractor on'or before thirty (30) days after the date of the notification by the Contractor the balance shown by said final statement as due the Contractor, under the terms of this Agreement. 51. B0.\TS The successful bidder shall be required to furnish a performance bond and payment bond in accordance with Article 5160, Vernon's Annotated Civil Statutes in the amount of 100% of the total contract price, in the event said contract price exceeds $25,000.00. If the contract price does not exceed $25,000.00, the statutory bonds will not be required. All bonds, if required, shall be submitted on forms supplied by the Ou-ner, and executed by an approved Surety Company authorized to do business in the State of Texas. And it is further agreed that this contract shall not be in effect until such bonds are so fur- nished. 52. SPECIAL CONDITIONS In the event special conditions are contained herein as part of the con- tract documents and said special conditions conflict with any of the general conditions contained in this contract, then in such event the special conditions shall control. 53. LOSSES FROM NATURAL CAUSES Unless otherwise specified herein, all loss or damage to the Contractor arising out of the nature of the work to be done, or from the action of the elements, or from any unforeseen circumstance and the prosecution of the same, or from unusual obstructions or difficulties which may be encountered in the prosecution of the work, shall be sustained and borne by the Contractor at his own cost and expense. 54. INDEPENDENT CONTRACTOR Contractor is, and shall remain, an independent contractor, with full, complete and exclusive power and authority to direct, supervise, and control his own employees and to determine the method of the performance of the work covered hereby. The fact that the Owner or Owner's Representative shall have the right to observe Contractor's work during his performance and to carry out the other prerogatives which are expressly reserved to and vested in the Owner or Owner's Representative hereunder, is not intended to and shall not at any time change or effect the status of the Contractor as an independent contractor with respect to either the Owner or Owner's Representative or to the Contractor's own employees or to any other person, firm, or corporation. 55. CLEANING UP The Contractor shall at all times keep the premises free from accumulation of debris caused by'the work, and at the completion of the work he shall remove all such debris and also his tools, scaffolding, and surplus materials I I- 20 and shall leave the work broom clean or its equivalent. The work shall be left in good order and condition. In case of dispute Owner may remove the debris and charge the cost to the Contractor. - No Text 1. CHANGES IN THE WORK The Local,Public Agency may make changes in the scope of the work required to be performed by the Contractor under the Contract or making additions thereto, or by omitting work therefrom,without invalidating the Contract, and without relieving or.releasing the Contractor from any of his obligations under the contract or any .guarantee given by him pursuant to the Contract provisions, and without affecting the validity of the guaranty bonds, and without relieving or releasing the surety or sureties of said bonds. All such work shall be executed under the terms of the original Contract unless it is expressly provided otherwise. Except for the purpose of affording protection against any emergency endangering health, life, -limb or property, the Contractor shall make no change in the materials used or in the specified manner of constru- cting and/or installing the improvements or supply additional labor,' services or materials beyond that actually required for the execution of the Contract, unless in pursuance of a' -written 'order from the Local Public Agency authorizing the Contractor to proceed with the change I. No claim for an adjustment of the Contract Price will be valid unless so ordered. If applicable unit prices are contained in the agreement (established as a result of either a unit price bid or'a Supplemental Schedule of Unit Prices) the Local Public Agency may order the Contractor to pro- ceed with desired changes in the work, the value of such changes to': be determined by the measured quantities involved and the applicable 3 unit prices specified in the contract; provided that in case of a unit price contract the net value of all changes does not increase or de- crease the original total amount shown in the Agreement by more than ° twenty-five percent (25%). 2. SUPERINTENDENCE The Superintendent and/or his assistants will not be allowed to serve two functions simultaneously, such as operating machinery and acting as superintendent at the same time. The superintendent must be free of individual•responsibilities to enable him to give the entire project,' his constant attention to facilitate the progress thereof. 3. PROSECUTION OF WORK t The Contractor may proceed with subgrade preparation of earthwork on any schedule that he may select and on any location in the contract unless hindered by factors beyond his control. Not more than three (3) calendar days shall elapse between the time subgrade preparation is begun and the time of spreading and compaction of the caliche base. III-1 11 During the construction the Contractor is to close to traffic streets as directed by the Engineer. The Contractor will.before starting any work on any street, erect barricades and signs, or provide sufficient flagmen to give notice to vehicular traffic, also two special trailer mounted signs and arrows flash left, right or both at the same time at least 25 times per minute, see detail 2-S-126 and Section 6E-7 of the traffic control manual. During the period the contractor is directing traffic over the base, the surface shall be satisfactorily maintained by the use of sprinkling and blading as required so that no hazard will result. The base course shall be maintained -until the wearing surface if placed thereon. At no time during the period of construction shall driveways and/or alleys be left impassable between the night hours of 6 P.M. to 6 A.M. except during the construction of the curb and gutter for which the driveways and/or alleys shall remain closed not more than 4 days including 72 hours for curing. The contractor will be required to place and level the caliche as each block is subgradAd and in no case shall the caliche be permitted to remain as dumped overnight. The contractor will during the progress of the work erect and maintain for twenty-four hours a day such barricades and warnings necessary to give notice to vehicular and pedestrian traffic of any and all obstru- ctions and will insofar as possible keep the streets and/or alleys on which work is being done in a passable condition. During the time that the curb and gutter is being poured and cured and until the caliche is leveled, the Contractor shall have flares and warning signs placed at each end of the block. When the subgrade excavation causes an abrupt drop in the driving portion of the street the Contractor shall level the drop by dumping a sufficient amount of approved caliche on the ' subgrade. During the time the concrete is curing in the alleys and until it can be opened to traffic, the Contractor shall maintain warning signs on barricades with flares at each end of the block until this alley can be opened to traffic. The flagmen will be required to wear vest and use the type of flag as shown on flagging detail sheet in specifications. All equipment working on the streets will at all times have at least two (2) red, orange or flourescent red -orange flags at least 16" x 16" in size. These flags shall be mounted high enough on the equipment so that they will be visible to all traffic meeting or passing the equip- ment. Before work is started on any street it will be the responsibility of the Contractor to notify each property owner that has a car or cars parked in their driveways or garages so that each owner might have the opportunity to move their cars. MI 11 The contractor shall schedule his work on major thoroughfares at least 15 days in advance. This will give the Engineer time to give notice to business by letter, and so that business may have time to adjust their plans. Immediately after each application of asphalt, re -construction or black base construction the Contractor shall clean, remove paper, surplus agg- regate or paving materials from the gutters, rubbish and temporary struc- tures from the street, restore in an acceptable manner all property, both public and private which has been damaged during the prosecution of the work, and leave the site of the work in a neat and presentable condition throughout. The cost of the "cleanup" shall be included as part of the cost of the various items of work involved, and no direct compensation will be made for this work. The contractor should familiarize himself with the Texas Manual on UNIFORM TRAFFIC CONTROL DEVICES for Streets and Highways, Part VI, published August 31, 1979. 4. BARRICADES AND DANGER, WARNING AND DETOUR SIGNS AND TRAFFIC HANDLING The Contractor shall have the sole responsibility for providing, installing, moving, replacing, maintaining, cleaning and removing upon completion of work, all barricades, warning signs, barriers, cones, lights, signals and other such type devices for handling traffic control as indicated in the plans or as directed by the Engineer. All barricades, warning signs, barriers, cones, lights, signals and other such type devices shall conform to details shown on the plans and as indicated in the Texas Manual on Uniform Traffic Control Devices. The Contractor may provide special signs not covered by plans to protect the traveling public against special conditions or hazards, provided however, that such signs are first approved by the Engineer. Upon completion of the work, all barricades, warning signs, barriers, cones, 1-ights, signals and other such type devices and evidence thereof shall be removed by the Contractor. 5. MAINTENANCE OF DETOURS The Contractor shall do such work as may be necessary to maintain detours and facilities for safe, public travel in accordance with the Traffic Control Plan and these specifications. There shall be maintained in passable condition, such temporary roads and structures as may be necessary to accomodate public travel. Temporary approaches and crossings of intersecting highways shall be provided and maintained in a safe and passable condition by the Contractor at his entire expense. 6. PUBLIC SAFETY AND CONVENIENCE The safety of the public and the convenience of traffic shall be regarded as of prime importance. It shall be the entire responsibility of the Contractor to provide for ingress and egress to private property. III-3 t Ingress and egress to private property shall be provided as specified in the plans or as directed by the Engineer. - The Contractor shall plan and execute his operations in a manner that will cause the minimum interference with traffic. The Contractor shall secure the Engineer's approval of his proposed plan of operation, sequence of work and methods of providing for the safe passage of traffic before it is placed into operation. If at any time during construction the approved plan does not accomplish the intended purpose, due to weather or other conditions affecting the safe handling of traffic, the Contractor shall immediately make necessary changes therein to correct the unsatisfactory conditions. At night or otherwise, all equipment not in use shall be stored in such manner and at such locations as not to interfere with the safe passage of traffic. The Contractor shall provide and maintain flaggers at such points and for such periods of time as may be required to provide for the safety and convenience of public travel and Contractor's personnel, and as directed by the Engineer. Flaggers shall be English speaking, courteous, well in- formed, physically and mentally able to effectually perform their duties in safeguarding and directing traffic and protecting the work, and shall be neatly attired and .groomed at all times when on duty. When directing traffic, flaggers shall use standard attire, flags and signals and follow the flagging procedures set forth in the Texas Manual on Uniform Traffic Control Devices for Streets and Highways. _ 7. WATER Water for this project will be furnished by the City of Lubbock at fire hydrants designated by the Contractor for which -there will be no charge. The Contractor will'be furnished loading racks by the City Water and Street Superintendent at no charge for the first rack but for each additional rack there will be a charge of ten dollars. The Contractor will also be charged ten dollars for each move of each loading rack after the first set-up. The loading rack will be equipped with a valve which will be pad -locked at all times except when the Contractor's truck is loading. The valve on the loading rack shall be used by the Contractor and -at no time will the Contractoruse the fire hydrant valve. The padlock on the rack valve shall be furnished by the Contractor. The Con- tractor shall not use any fire hydrants for water loading unless there is an authorized rack on the fire hydrant. The Contractor will not be allowed to use water from authorized loading racks except on City approved projects. Water, which is supplied by the City, is intended for use in compacting subgrade and base and maintaining dust control. It is not the intention of the City to furnish water for use in mixing concrete. 8. RESTRICTIONS AND REQUIREMENTS FOR CONSTRUCTION A. The contractor will need special permission to be permitted to work on weekends or legal holidays and shall do no work on any contract item before daylight or later than one hour after sundown. (see exception in General Instructions to Bidders.) No work will be allowed between Nov- ember 1 and January 2, unless approved by the Engineer. ,B. All paving or work performed by the paving contractor, shall be guaranteed by a one year Maintenance Bond from the Contractor before final acceptance of the work. The guarantee is for one year after final acceptance by the owner. III-4 C. A 1:2 dilute emulsion treatment at a rate of .10 gallon per square yard will be applied to the A.C. surface within ten days of the placement of the A.C. surface. D. The contractor will not be allowed to place the A.C. surface when the ambient temperature is less than 550F. The Contractor may apply the A.C. paving surface when the ambient temperature is 550F or above and wind velocity is equal to or less than 10 miles per hour or when the ambient temperature is 60OF or above. The engineer may use his discretion to require a cover over the asphaltic mixture when being hauled from the plant to the job site. E. The asphaltic surface will have a minimum temperature of 300 degrees F. immediately after.placement by the lay -down machine unless other- wise approved by the Engineer, F. Standby rollers shall be located at the job site for immediate use if needed. G. Proof rolling will be required on subgrade, caliche base, black base, embankment or surface. After rain showers if deemed necessary by the Engineer each item that was approved will be re -rolled. The proof rolling will be performed with six passes over the area using a self- propelled 35 ton pneumatic roller with certified weight certificate. H. Preliminary approval, by the Engineer, of aggregate at the pit and crusher location shall be required, prior to delivery to the plant. Final approval of the stockpile material, at the hot mix plant or concrete plant, or stockpile locations will be required by the Engineer, after which no additional aggregate will be added to the approved stock- pile prior to entering the mixing plant, or used in two -course surface. I. During the period of re -construction and two course construction the contractor will not use private driveways for turning or parking his equipment any damage to sidewalks, driveways, slabs or curb and gutter will be replaced at the Contractor's expense. J. During the re -construction, the black base and two -course construction at no time will the contractor completely close any street to alltraffic without the Engineer's approval. On most major thoroughfares only one- half will be reworked at a time and on some narrow streets the full width will be reworked. On the two -course streets one-half will be closed and the traffic will be detoured on the other side. When business are on one or both sides, shorter shots will be made to cause less incon- venience to the public and the businesses. K. Before any portion of any street is closed to traffic the Contractor will be required to have sufficient equipment on the site to start the re- construction, and at no time will any section of the closed area be left three (3) days without some type of work being performed. If there is a shortage of equipment to work on all areas of the closed section then the Contractor will be required to provide additional equipment before the next area is closed. After the work is started, no equipment will be moved from this site to another. It is the intent of these requirements to reconstruct and place the two -course on the streets as listed in this con- tract with the least inconvenience to the property owners and the traveling public. III-5 (Contd.) K. In the event damage occurs to pavement in the area of the fire hydrant, which was caused by the Contractor's employees negligence to shut off the valve on the loading rack, it will be'the Contractor's responsibility and expense to repair the paving and replace curb and gutter if required by • the Engineer. L. At no time during the construction, re -construction or two -course main- tenance will any equipment be taken across any curb or gutter, valley • gutter, alley return sidewalk without first placing -a dirt or caliche fill of at one foot above the existing concrete, any broken or damaged concrete because of equipment will be removed and replaced at the contractor's expensc 9. REMOVING OBSTRUCTIONS The Contractor shall familiarize himself with the existing obstructions inclu- ding sidewalks, trees, poles, etc., prior to building. It shall be the Con- tractor's responsibility to remove these obstructions at the direction of the Engineer except that the utility companies will move their equipment at no - cost to the contractor. The contractor will receive no compensation for delay caused by the Utility Companies in relocating or removing their equipment. 10. TESTS OF MATERIALS In general, the contractor will bear the cost of all material tests, some of which are listed: 1. Caliche Base Materials: Before materials can be used on any street, current not older than 45 days) test reports will be submitted to the Engineer for approval. 2. Concrete mix design and at least three compression test made by a com- mercial laboratory submitted to Engineer for approval. 3. Cement certified mill test on each car for cement. 4. Asphalt certified lab test. 5. Concrete Aggregate all crushed stone or gravel shall have a minimum of eighteen percent(18%) loss when tested by five (5) cycle magnesium sulfate soundness test A.S.T.M. C-88-76 and Test Method Tex. - 411-A and 413-A. Paving Aggregate all gravel, pre -coated gravel or pre -coated crushed stone shall have a maximum of twenty percent (20%) loss when tested by the four (4) cycle magnesium sulfate, soundness test A.S.T.M. C-88-76. Pre -coated or crushed gravel shall have a minimum of 85 percent of particles retained on the No. 4 sieve with at least one crushed ,face, as determined by Test Method Tex.-413-A. 6. Base Density Test The City of Lubbock Testing Laboratory will provide density test on the caliche base or black base. Should the contractor question the results of these test, the contractor may, at his own expense, obtain a commercial, laboratory for testing and comparison. NOTE: See Section IV-10-D page 25 (laboratory) control for retesting material where irregularities occur and the limits of the specifications are exceeded • for aggregate, base materials, black base and hot -mix and concrete construction. III-6 A copy of all test reports, obtained and submitted to a commercial laboratory by the contractor, shall be sent to the Engineer for file and record irre- gardless of the outcome or results of the tests. 11. SUBCONTRACTOR The Contractor shall not award any work to any subcontractor without prior written approval of the Owner, which approval will not be given until the Contractor submits to the Owner a written statement concerning the proposed award to the subcontractor, which statement shall contain such information as the Owner may require. The Contractor shall be as fully responsible to the Owner for the acts and omissions of his subcontractors, and of persons either directly or indirectly employed by them, as he is for the acts and omissions of persons directly employed by him. The Contractor shall cause appropriate provisions to be inserted in all subcontracts relative to the work to bind subcontractors to the Contractor by the terms of the General Conditions and other contract documents insofar as app- licable to the work of subcontractors and to give the Contractor the same power as regards terminating any subcontract that the Owner may exercise over the Contractor under any provision of the contract documents. Nothing contained in this contract shall create any contractual relation between any subcontractor and the Owner and said subcontractor will look exclusively to contractor for any payments due subcontractor. 12. UNDERGROUND UTILITIES The contractor's attention is directed to the fact that pipelines and other underground installations as may be shown on the plans have been taken from the best available information. There may be other pipelines or installations. The Contractor shall save harmless the City from any and all suits or claims resulting from damage by his operations to any pipeline or underground installa- tion. It is the Contractor's responsibility, during the period of street construction, to insure that all utility cuts in the limits of street construction have been properly backfilled, compacted and the top 6" inches backfilled with 3-sack concrete. It is not the intent to require the contractor to provide for the utility cut repair but for the individual utility company making the cut to provide their own repairs. In the case of a City underground installation, the Contractor may be required, at the Engineer's option, to repair the cut with 3 sack cement stabilized caliche at the unit price bid. 13. LABOR The Contractor must abide by the Wage and Hour Laws of the State of Texas, or the U.S. Department of Labor, and must not pay less than the rate legally prescribed or as set forth herein, whichever is higher. Payment for time worked over forty -hours per week shall be made at one and one-half (1-1/2) times the above prevailing rates. Payment for time worked on legal holidays shall be paid at two (2) times the regular governing per diem wage rates. Any laborer, workman or mechanic required or permitted to work in excess of TTT_7 eight (8) hours per calendar day, under the emergency exceptions to House Bill No. 115 of the 44th legislature invoked by HCR No. 201 of the 47th legislature shall be paid on the basis of eight (8) hours constituting a days work. The prevailing wage rates for this contract are shown in the following pages. 14. DISPOSITION OF ASPHALT AND BASE MATERIALS The existing asphalt surface on streets to be reconstructed with 6 (six inches) or 9 (nine inches) of black base shall remain the property of the City of Lubbock.

Care will be taken to prevent dusty conditions in the stockpile area from any sources. IV-1 C. Water Water shall be clean, clear, free from oil, acid or organic matter and free from injurious amounts of alkali, salts or other chemicals. D. Concrete Materials Test Pre -Construction Tests The contractor will submit testcertificates from an approved commercial laboratory on all 'aggregates proposed for use on this work. Tests should be made approximately 20 days before beginning the concrete operation. The contractor will submit in advance of construction the design mix and the result of compression tests made by a commercial lab- oratory. These will be made on each type of concrete mix design proposed for.use on this project. Tests shall be made on 6 cylinders for each mix, 3 tested in 3 or 7 days, 3 tested at 7 or 28 days. Additional tests shall be furnished if material source is changed or if concrete used varies from the original design. Construction Tests Tests of the aggregates and the concrete will be made by the Engineer during construction to determine conformity with the specifications. Test cylinders will be made in accordance with - the Method.of Making and Curing Concrete Compression and Flexure Test Specimens in the Field (ASTM Designation C-31). The specimens shall be cured under standard moisture and temperature conditions in'accordance with the requirements of ASTM C-31. Strength tests shall be made, in general, for each day's run or. for each 50 cubic yards of concrete if a day's run greatly exceeds this amount but these tests may be made entirely at the discretion of the Engineer. The costs of all such testing will be borne by the City but the Contractor shall cooperate in securing and storing samples and shall furnish all materials required for sampling. A strength test shall consist of five standard test cylinders made from a composite sample obtained in accordance with the requirements of ASTMM Designation C-172. Two of the cylinders shall be tested at 3 or 7 days and two at 7 or 28 days. The fifth cylinder shall be held available for subsequent testing, if determined necessary by the Engineer." The test result shall be the average of the two 7 or 28 day specimens, except that, if one specimen in the test shows manifest evidence of improper sampling, molding, or testing, s it shall be discarded and the remaining two strengths averaged. Should more than one specimen representing a given test show definite defects, due to improper sampling, molding or testing, the entire test shall be discarded. The result of the 7 or 28 day strength tests shall be used as the basis for accepting or rejecting the concrete represented. IV-2 The results of the 3 or 7 day strength testis will be compared with the.3 Qr 7 day s.trength_of the preconatruction test cylinders for the type and slump of the concrete being produced. Should the 3 or 7 day strengths indicate a deficiency in the 7 or 28 day strengths,. the Engineer may require a temporary change in proportions to correct such deficiency. Such change shall remain in effect until the 7 or 28 day strength of the material in question is determined, at which time the change shall become permanent or shall be rescinded, depending upon the results of the 7 or 28 day test. The engineer shall record the delivery ticket number for the concrete and the exact location in the work at which each load represented by a strength 'test is deposited. E. Concrete Design Concrete conforming to these specifications may be "Ready Mix" but transporting vehicles shall be operated such as to insure delivery and placement in forms without loss or segregation of ingredients and within one hour of mixing time.

The sequence of compacting shall be such that undue displacement of the edge of the course does not occur. On deep lifts, the edge of the course may be rolled with a motor grader wheel or similar' equipment or supported by blading a roll of earth against the edge of the course prior to compacting the surface. When the asphaltic mixture is placed in a narrow strip along the edge of an existing pavement, or used to level up small areas of an existing pavement or placed in small irregular areas where the use of a finishing machine is not practical, the finishing machine may be eliminated when authorized by the Engineer, pro- vided a satisfactory surface can be obtained by other approved " methods. I. COMPACTING (1) As directed by the Engineer, the asphalt stabilized base shall be compacted thoroughly and uniformly with the specified rollers. In lieu of the rolling equipment specified, the Contractor may, upon written permission from the Engineer, operate other compacting equipment that will produce equivalent relative compaction .as the specified equipment.

When directed by the Engineer, the initial compaction shall be accomplished with the pnuematic tire roller. (2) When rolling with the three wheel, tandem, or vibratory rollers, rolling shall start longitudinally at the sides and proceed toward the center of the pavement, overlapping on successive trips by at least half the width of the rear wheel unless otherwise directed by the Engineer. Alternate trips of the roller shall be slightly different in length. On super -elevated curves, roll- ing -shall begin at the low side and progress toward the high side unless otherwise directed by the Engineer. When rolling with vibratory steel wheel rollers, the manufacturer's recomm- endation shall be followed unless directed otherwise by the Engineer. Rolling with pneumatic -tire roller shall be done as directed by the Engineer. Rolling shall be continued -until no further increase in density can be obtained and all roller marks are eliminated. The motion of the roller shall be slow enough at all times to avoid displacement of the mixture. If any dis- placement occurs, it shall be corrected at once by the use of a rake, and of fresh mixtures where required. The -roller shall not be allowed to stand on any portion of the mixture pavement which has not been fully compacted. To prevent adhesion of the mixture to the roller, the wheels shall be kept thoroughly moistened with water, but an excess of water will not be per - witted. All rollers must.be in good mechanical condition. Nec- essary precautions shall be taken to prevent the dropping of gasoline; oil, grease or other foreign matter on the roadway, either when the rollers are in operation or when standing. IV-20 Hand Tamping. e The edges of the pavement along curbs, headers and similar structures, and all places not accessible to the roller, or in such positions as will not allow through compaction with the rollers, shall be thoroughly compacted with lightly oiled tamps. J. SURFACE FINISH The compacted material shall conform to the typical cross sections,. lines and grades as 'shown on plans and directed by the Engineer and shall have a smooth surface with a reasonably uniform texture acc- eptable to the Engineer. Unacceptable finished surfaces may be corrected by the placement of additional mixture, all at the expense of the Contractor. K. PROTECTION'OF THE WORK AND OPENING TO TRAFFIC The completed asphalt stabilized base course shall be opened.to traffic as provided by the plans and as directed by the Engineer. All construction traffic allowed on the base course shall comply with the State laws governing traffic on highways unless other- wise authorized by the Engineer. When another roadway surface is provided for the traveling public and construction traffic through the project, the Engineer may prohibit traffic on the completed base course. L.

This -design will stay in the limifs of the above Type."C" b-ut may vary from th-e upper limits of certain sieve designations to the lower limits of other -sieve designations. LABORATORY CONTROL If the Contractor or supplier wish to use a material or location not pre- viously approved by the City of Lubbock, he will be required to furnish a complete suite of tests, as requested by the Engineer, -on the mix design for acceptance and approval. The City of Lubbock will utilize its own testing laboratory to monitor the plant mixing for Black Base and Hot Mix. This laboratory control will be provided by the City of Lubbock. A representative of -the City Engineer will be at the plant with full authority to control the mixing operation.. In those instances where irregularities occur and the limits of the spec- ificationstare exceeded for.aggregate, black base, or hot mix, appropriate corrections will be required. Should the contractor question the results of City laboratory test, four samples will be tested, at the Contractor's expense in the following manner: one by the City laboratory, one by a local comm- ercial lab, and two by two separate out of town labs. The results of such testing to be evaluated by the City Engineer. E. TOLERANCES The Engineer will designate the exact grading of the aggregate and asphalt content to be used in the mixture. The paving mixture produced shall not vary from the designated grading and asphalt content by more than.the_toler- ances allowed herein and shall remain within the limitations of the -master grading specified. The respective tolerances, based on the percent by weight of the mixture, are listed as follows: Per Cent by weight Passing 5/8" sieve, retained on 3/8" sieve. . . . . . . . + or -3 Passing 3/8" sieve, retained on No. 4 sieve . . . . . . . . . + or -3 Passing No. 4 sieve, retained on No. 10 sieve . . . . + or -3 Total retained on No. 10 sieve. . . . . . . . . . . . . . + or -3 Passing No. 10 sieve, retained on No. 40 sieve. . . . . . + or-2 Passing No. 40 sieve, -retained on No. 80-sieve. . + or -2 Passing No. 80 sieve, retained on No.'200 sieve . . . . . + or -2 Passing No'. 200 sieve .

EXTRACTION AND GRADATION TESTS , Samples of the mixture when.tested in accordance with Test Method Tex-210-F shall not vary from the grading proportions of the agg- regate and the asphalt content,designated by the Engineer by more than the respective tolerances specified above. (See Section Its-7-C (1) for methods of extraction.of asphalt) During construction, if grading or asphalt content exceeds the tolerances stated herein, production will be discontinued until such time as the Hot -Mix Asphaltic Conctete mixture has been corrected and subsequent grading and extraction tests indicate results within the tolerances stated herein. All Hot Mix Asphaltic Concrete mxiture so constructed, which exceeds the tolerances as stated herein, will be removed and replaced at no cost'to the Owner. (1) Sampling and Testing It is the intent of this specification that the mixture will be designed to produce a mixture of optimum density and stability, as determined by the Engineer, when tested in accordance -with these specifications and applicable ASTM procedures. Thoroughfare Residential Traffic Traffic .(2) Design Method Min. Max. Min. Max.

'If the -laboratory stability and/or density of the mixture produced has a value lower than that specified, and in the opinion of the Engineer is not due' to change in source or quality of materials, production may proceed, and the mix shall be changed until the laboratory stability and density equals or exceeds the specified values. If there is, in the opinion of the Engineer, an apparent change in any material from that used in the design mixtures, production will be dis- continued until a new design mixture is determined by trial mixes. 11. SILO STORAGE A silo storage system may be used during the normal day's operation. The mixture coming out of the silo storage must be of equal quality and temperature -to that coming out dr the mixing plant. Any operation that has a tendency to segregate the mixture ae fails to maintain a thorough and uniform mixture and temperature shall not be used. If any load of mixture coming out of the silo storage sys-:err fails to meet the asphalt specifications or gradation requirements, then the total contents of the silo storage system shall be condemned. EARRICADES'AND SIGHTS Barricades shall be constructed of clean, sound lumber, shall be of first- class workmanship, and all surfaces above ground shall be painted with an approved brand of white paint to secure thorough coverage and a uniform white color. In no case shall less than two coats be used. The paint for barricade stripes shall be reflective orange and reflective white. All dimension striping,. ; lighting, painting, coloring and placement of barricades shall be in accordance to the details and design as set forth in the Texas Manual on UNIFORM TRAFFIC CONTROL.DEVICES for Streets and Highways, Part VI, issued in May, 1983. The contractor shall maintain each barricade in a neat and acceptable condition and furnish replacements when necessary or requested by the Engineer. Each sign shall'be displayed only for the specific purpose prescribed for it. Before any detour or temporary route is opened to traffic all necessary Reg •ulatory, Warning and Guide signs shall be in place., Signs required by temporary conditions or restrictions shall be removed immed- iately_ when those conditions cease to exist or the restrictions are withdrawn. Guide -signs directing traffic to and on temporary routes or detours shall be removed when no longer applicable. Important as is standardization with respect to design and placement, uni- formity of application is equally important. Identical conditions should always be marked with the same type of sign, irrespective of where those particular conditions occur. All signs that are to convey their message during hours of darkness shall be re- flectorized or illuminated. Signs for daytime use only may be non-reflectorized but a flourescent background material will be used for increased daytime visi- bility if requested by the Engineer. Where there is serious interference from extraneous light sources, and a re- _ flectorized sign is not likely to be effective, an illuminated sign will be used. Construction warning signs shall have'a black legend .on an orange background and shall conform to the standards.as to size, shape and color as outlined in the Texas Manual on UNIFORM TRAFFIC CONTROL DEVICES mentioned Barricades, flares, and signs are a necessity in the construction involved in this contract. The provision of these items by the contractor should be considered in the -bid prices submitted, as no separate compensation trill be made,. unlessindicated otherwise in the plans or the proposal. No work will be'permitted on any project prior to installation`of barricades or other warning devices at beginning and end of construction area. IV-2 7 f DETAILS OF CONSTRUCTION DETAILS FOR PATCHING WITH BLACK BASE AND 6"-OF THREE (3) SACK CEMENT STABILIZED CALICHE PATCHING WITH BLACK BASE Patching shall include removing the existing surfacing, six (6) inches of the caliche base, if sub -grade is unstable it.will be removed and replaced with black base. Six (6) inches of black base will be placed in lifts and each lift will be compacted until the next lift is placed. The edges of the patch shall be vertical and shall be tacked before placing the black base and the 1-1/2 inches of type "C" hot -mix. The black base and hot -mix shall be rolled until the required density is obtained. All hot -mix edges will meet the grade of the existing surface. PATCHING WITH 6" OF THREE SACK CEMENT STABILIZED CALICHE Same as above except six (6) inches of three (3) sack cement stabilized caliche will be used in lieu of six (6) inches of black base. At all times the patched area will be barricaded, if open to traffic before the Type "C" mix is placed the edges of the patch will be leveled up with mix to eliminate the bumps. V- la • SECTION V DETAILS OF CONSTRUCTION SEALING AND TWO -COURSE SURFACE TREATMENT 1. PREPARATION OF SURFACE Before the sealing operation is started the Contractor will be required 'to patch all areas that have failed or raveled as marked by the Engineer. The City of Lubbock Street Department will sweep the streets before the two -course operation is started. Asphalt shall not be applied when general weather conditions, in the opinion of the Engineer, are not suitable. 2. HANTLING AND APPLYING ASPHALT All storage tanks, piping, retorts, booster tanks and distributors used in storing or handling asphalt shall be kept clean and in good operating condition at all times, and they shall be operated in manner that there will be no contamination of the asphalt with foreign material. Asphalt is not to be heated above 400 degrees F at any time, and when applied, a it shall be at a temperature which will insure a Furol Viscosity of between 50 and 60 at the time of application. The Engineer will select the temperature of application, and the contractor shall apply the asphalt at a temperature within 15 degrees of the temperature selected. All asphalt material heated above 400 degrees F will be rejected. • Recirculating tank car heating equipment shall be equipped with an approved type recording thermometer. Asphalt shall be applied to the clean surface by an approved type of self propelled hydro -statically controlled pressure distributor so operated as to distribute the material in the quantity specified, evenly and smoothly, under pressure necessary for proper distribution. The Con- tractor shall provide all of the heating equipment and in the distributor, for determining the rate at which it is applied, and for securing uniformity at the junction bf two distributor loads. The beginning and ending of each shot of asphalt shall start and stop on a strip of heavy kraft paper _ of not less than thirty inches in width. Asphalt for pre -coated seal coat and two -course applications shall not be applied unless covering with aggregate is assured within ten (10) minutes. No asphalt shall be applied when wind velocity is 25 M.P.H. or more. Any block or blocks that receives a seal coat or two -course asphalt application that exceeds the rate set by the Engineer by .04 or more will not be accepted until the bleeding is stopped. The Contractor will be, required at his expense to furnish extra rock and equipment necessary to control this bleeding. After the bleeding is stopped, the City will then assume the maintenance of the block or blocks that were shot heavy. 11 V-lb m Application of asphalt on street returns shall be accomplished by the. distributor bars unless otherwise directed by the Engineer. In areas regarded by the Engineer as inaccessible to the distributor, asphalt shall be applied by means of a hose and spray nozzles attached to the distributor. Care shall be taken during application of any asphalt to shield the curb and gutter from asphalt spray. Manholes and valve boxes will be covered before each application of asphalt and immediately uncovered after the application of aggregate and before rolling operations. Successive applications of asphalt shall be made in the same manner after application aggregate. 3. RATE OF APPLICATION OF MATERIALS S. H. D. Gals. Spread Grade No. of Asphalt/S.Y.

Pre -coated crushed stone or crushed gravel) #2 Special 0.25 1:60 #4 0.35 1:88 4. HANDLING AND APPLYING AGGREGATES Immediately after making the first application of asphalt over the full width of the street, the surface shall be covered with aggregate, spread with an approved type self-propelled aggregate spreader on which the rate of application of rock and the speed of travel may be contorlled by the operator. Applications shall be at the rates herein specified or at rates as directed by the Engineer. After the aggregate has been spread, it shall be bladed with an approved blade grader and broomed with a heavy drag broom. If necessary to obtain a uniform distribution of aggregate or to fill low areas, hand spotting and hand brooming of the aggregate shall be required. Care shall be taken in dip sections to maintain an accurate flow line. Considerable hand work may be required at intersections and at joints in order to maintain a uniform distribution of the aggregate, to prevent the incorporation of foreign materials such as caliche and dirt, and to construct smooth joints. In any event, care shall be taken to avoid pulling the drag broom over dirt or caliche surfaces or over wasted aggregate at the edges of the area being surfaced. V :lc a After the first and second application of aggregate on the two -course it will be thoroughly rolled with pneumatic rollers, bladed, dragged and all thin spots spotted with extra aggregate then bullwheeled with an approved three -wheeled roller weighing not less than ten (10) tons. Aggregate on seal coat will be dragged with a drag broom and all thin spots covered with extra aggregate and thoroughly rolled with pneumatic rollers. In all cases, rolling shall be continued until the surface presents a smooth appearance. Gutter edges shall be cleaned of aggregate before such application of asphalt and this aggregate will not be "ridged" along the gutter edge but if placed back on the surface area shall be well scattered. There should be a slight excess of aggregate on the surface after completion of the work as specified above. Care shall be taken in loading aggregates from the.stockpiles to. pre- vent getting dirt and other foreign matter into the aggregates. Loads of aggregate containing dirt will be rejected. 4 5. HANDLING AND APPLYING ASPHALT AND AGGREGATES FOR NIGHT WORK Application of asphalt and aggregates at night shall be applied by the same methods as for daylight application except that all equipment that is to be used on the streets after dark shall have sufficient lights in compliance with State vehicle code. Additionallights will be required on the back end of the asphalt distributor, the aggregate spreader and at the aggregate stock pile area. (No night work will be authorized unless approved by the Engineer.) a 6. REQUIRED ROLLING (1 HOUR PER 1000 S.Y. OF SURFACE SEALED) The completed asphalt surface shall be broomed and rolled with pneumatic rollers immediately after the asphalt is covered with aggregate. The .entire surface that is sealed will receive on hour rolling for each 1000 S.Y. the same day that the asphalt is applied no back rolling will be permitted (unless a rain storm occurs during the day then that sur- face may be rolled the next day). AT least three pneumatic rollers will roll directly behind the aggregate spreader and drag broom, each roller making several complete passes across the entire width of the street, additional pneumatic rollers will follow approximately one block behind the first three rollers of which each additional roller will make several complete passes across the entire width of the street until one hour of rolling has been obtained for each 1000 S.Y. before moving on to the next block. The City will assume maintenance on these streets ' the following day after the rolling has been completed. V-ld 7. CLEANUP I Immediately after each application of asphalt, the Contractor shall clean, remove paper, piles of asphalt from manholes and water valves, extra aggregate that is in the gutter, rubbish and temporary structures from the street, restore in an acceptable manner all property, both public and private, which has been damaged during the prosecution of the work, and leave the site of the work in a neat and presentable condition throughout. The cost of the "cleanup" shall be included as part of the cost of the various items of work involved, and no direct compensation will be made for this work. This work shall be done before final acceptance. s I V-le s DETAILS OF CONSTRUCTION 1. CONCRETE A. Curb and Gutter ( C1:ass A -'Concrete) Descriytion This item shall consist of Portland Cement 30" concrete curb and gutter or 30" separate gutter as shown on the plans or as directed by the Engineer, and shall be constructed of Class A concrete, Included in the curb and gutter item is the subgrade preparation and the filling and shaping of the area behind the curb. ` (1) Curb Openings Separate gutter sections will be placed only across alleys and driveways presently in use or where definitely planned for future property improvements. It shall be the responsibility of the contractor to contact the property owner and determine the proper location of driveways before curb and gutter is constructed. All gutters across new or proposed driveways must meet the requirements set forth in the City Sidewalk and Driveway Regulations, Ordinance Number 14'66 and amendments thereto and gutters across existing driveways will be required to conform to said regulations if no. hardship to the existing property improvements is involved. In any event, all curb and gutter to be poured must have the engineer's approval as to driveway widths and location, in addition to the section, line and grade approval, before any pour is started on any curb and gutter unit. (2) Excavation and Subgrading (See Page V-24)r:_-,- - Excavation for the curb and gutter shall be made with the excava- tion of the entire street. The excavation shall be done to the lines and grades set by the engineer and in such a manner as to require a maximum 1/2" (inch) of fill to bring the subgrade to the correct elevation. Subgrade that is undercut 1" (one inch) or more shall be brought to the correct elevation by scarifying, wetting, disking, blading, rolling and compacted to 95% Standard Proctor Density (A.S.T.M. D-698) with pneumatic rolling to correct elevation prior to setting forms. Before completion of curb and gutter, ALL traffic signs and street name markers found in the way of paving will i=mediately be relocated behind the proposed curb and gutter by the Contractor. V-1 (3) Setting Forms Forms for concrete curb and gutter shall be set to the lines and' grades established by the engineer after the subgrade has been prepared. The forms shall be held together and in place in such a manner that they will not move during the placing and working of the concrete. The forms shall be cleaned and oiled prior to pouring concrete. Face forms and construction joints (removable metal plates) shall be set to hold the concrete for the curb in place until it is to be finished. Y Forms for radii shall be set in the same manner as the straight - forms -except that no face form will be required .if a true section is obtained by other methods. The.radii forms shall be.set in such a manner that the curve will be true. (4) Placement (Including Making Joints) Sufficient concrete shall be placed to allow for shrinkage and extra material for finishing, and the concrete shall be floatad and troweled to the approximate section, and only after the concrete receives a partial set shall the face forms be removed. The section shall then be shaped to the true cross-section by the use of a metal -screed which is shaped to the true cross-section. A "mule" screed shall be used only to shape to true cross-section when topping material is provided and pushed along on the front edge of the mule. Curb and gutter shall be constructed with an expansion joint at the tangent point of each return at intersections and at intervals of not more than forty'(40) feet between the intersections. Forty feet intervals may be waived if curb and gutter machine is used. Expansion joints shall be of the material hereinbefore specified. Construction joints formed by removable metal plates (templates) accurately shaped to the cross-section of the curb and gutter shall be located at the mid -point of each section between expansion joints.or as directed by the Engineer. Contraction joints shall be,placed at ten foot intervals. All joints shall be perpendicular to the surface of the concrete and to the axis of the section. (S) Finishing A ten (10) foot metal "straight -edge" shall be used to strike the flow line to grade, continuously along the flow line of the gutter. This operation shall be followed with a four (4) foot spirit level to assure the continuous grade down the flow -line the length of the gutter. V-2 13 Curb and gutter shall be finished uniformly by steel trowelling to an accurate cross-section.. The final finish will be accomplished with a brush,_ the last stroke being one from the back of curb to the lip of gutter. Both sides of all joints, the lip of gutter, and the back edge of the curb shall be finished with a 1/4" radius edging tool before the final brushing:. Curves at the top and bottom of the curb section shall present a uniform appearance without "waves" in the fact of the curb or "pockets" in the gutter. Concrete shall not be poured during sand storms: Concrete shall be -protected to maintain temperatures of not less than 50 degrees F. for five days after placement. If aggregate and water are heated, they shall not be heated above 90 degrees F. Concrete shall not be placed when the ambient temperature is less than 40 degrees F. ` It shall be the responsibility of the contractor to anticipate as nearly as possible changes in weather conditions which would affect the placement and protection of the concrete, and to be prepared to protect freshly placed concrete when sudden changes in the weather make such protection necessary. (6) Removing Forms Special care is required of the contractor in his removing of pins and moving of forms. Pins shall be pulled from the ground to free forms. If hammering is found to be necessary, a light, one (1) pound hammer shall be used. The contractor shall not place forms or pins on newly finished concrete. Loading and unloading of forms from a truck shall be executed by two workmen. It is the duty of the contractor to remove any warped forms found in any section of forms, before it is poured. When forms are pointed out as defective, those forms shall then be removed from the job site and not returned until they have been inspected by the Engineer. (7) Machine Laid Curb and Gutter Class A concrete shall be used for machine laid curb and gutter. The slump of the concrete shall be as directed by the Engineer. Reinforcing -steel, if required, shall conform to Section 3 under Materials of Construction. The curb and gutter shall be laid by an extrusion machine approved by the Engineer. Immediately prior to placing the curb and gutter, • the previously approved foundation -shall be thoroughly cleaned. The line for top of curb shall be maintained from a guideline set • by the Contractor from survey marks established by the Engineer. Curb outline shall strictly conform to the details shorn on the s plans. V-3 • The approved mix shall be fed into the machine in such a manner and at such consistency that the finished curb will present a well compacted mass with a surface free from voids and -honeycombs and true to established shape, line and grade. Additional surface finishing shall be performed immediately after extrusion. Unless otherwise specified by the Engineer, joints shall be constructed as follows: Expansion joints shall be located at each end of radius at intersections and alley returns and at the beginning of the pour,"and dummy grooved joints shall be spaced at 10 foot intervals between the expansion joints. (8) Curin All concrete work shall be.covered with heavy water -proof type paper to prevent loss of moisture and.to-prevent direct sunlight from striking the concrete, as soon.as as it has set sufficiently enough to prevent marking. In lieu of this method of curing, the curb and gutter may be cured by applying a liquid membrane coating to all exposed surfaces, provided such material and method is first approved by the Engineer. (9) Filling Behind Curb After the forms are removed and the concrete has cured, the contractor shall fill the area behind the curb with top soil. The area between the sidewalk and the curb or property line and curb, if no sidewalk exists, shall be leveled and sloped toward the curb in a manner satisfactory to the property owner and/or Engineer. Fill should be done prior to dumping caliche. (10) Replacement of Damaged Curb and Gutter or Gutter No patching of any nature shall be allowed in repairing any damage to curb and gutter or gutter which occurs during the construction process of paving improvements in any unit prior to the acceptance of said unit. Where damage occurs, the section of curb and gutter or -gutter containing the damaged portion shall be removed to -the nearest joints and shall be replaced with new construction, prior to surfacing of that section of street. ' Concrete surface finish marred by vandals, rain or sand during setting time shall be immediately repaired with an approved epoxy material; all abused concrete surface, along withstructural damage and defective flow line found at time of surfacing shall be handled as described in sentence 2 above.

The mats may be clamped or wired so that the mats will retain the horizontal and vertical alignment as specified by the plans or as approved by the Engineer. Deformed wire may be used for tie bars and load transfer bars that require bending. V-12 When fabricated steel bar or rod mats are specified, the mats shall meet the requirements of ASTM.Designation: A-184. (11) Mechanical Vibratory Equipment All concrete placed for pavement'shall be -consolidated by approved mechanical vibrators and designed to vibrate the concrete internally. The internal type will be used for full -depth placement. Vibratory members shall extend across the pavement practically to, but shall not come in contact with the side forms. Mechanically -operated vibrators shall be operated in such manner as to not interfere with the transverse or longitudinal joints. Separate vibratory units shall be operatedat sufficiently close intervals to provide uniform vibration and consolidation to the ' entire width of the pavement. The frequency in air of the internal spud type vibratory units shall be not less than 8,000-cycles per minute and not less than 5,000 cycles pei minute for tube types and the method of operation shall be as directed by the Engineer. The Contractor shall have a satisfactory tachometer available for checking the vibratory elements. The pavement vibrators shall not be used to level or spread the concrete but shall be used only for purposes of consolidation. The vibrators will not be operated where the surface of the concrete, as spread, is below the elevation of the finished surface of the pavement, except for the first lift'of concrete where the double strike off off method of placement is employed, and the vibrators shall not be operated for more than 15'seconds while the machine • upon which they are installed is standing still. Approved hand manipulated mechanical vibrators shall be furnished in the number required for provision of proper consolidation of the concrete along forms, at joints and in areas not covered by mechanically controlled vibrators. These vibrators shall be sufficiently rigid to insure control of the operation position of the vibrating head. Complete and satisfactory consolidation of the concrete pavement is a a most important requirement of this specification. Cores taken shall be carefully examined for voids, honeycombing or other evidence of incomplete consolidation. If such evidence is present, changes in the consolidation procedures.and/or equipment will be made to insure satisfactory consolidation. (12) Finishing Equipment a Where hand finishing is permitted under this specification, the Contractor shall provide a strike template and tamping template both -of 4 by 10 inch lumber or equivalent metal section and at least 2 feet longer than the width of the pavement. Both templates shall c. conform to the crou*n section of the pavement, and the tamp, if of wood, shall have a steel face not less than 3/8 inch in thickness. The Contractor shall also provide a longitudinal float of approved design and not less than 14 feet in length. Unless otherwise specified.on plans, the Contractor shall furnish a seamless burlap drag for finishing the pavement. The burlap drag shall consist of four or more plies of 10-ounce burlap fastened to a bridge to form a continuous strip of burlap the full width of the pavement and with approximately three feet of its width in contact with the pavement surface. To increase texture depth, the Engineer may require removal of transverse threads from the trailing six to twelve inches of the drag. Burlap drags shall be maintained clean and free of encrusted mortar The contractor shall furnish, operate and maintain at least two standard 10-foot steel s traigh tedges . The Contractor shall furnish a sufficeint number of bridges equipped to span the pavement for finishing operations and for the installation and finishing of joints and center stripes. All necessary finishing and edging tools shall be furnished as may be required to complete the pavement in accordance with plans. (13) Proportioning of Concrete Concrete shall be composed of Portland cement, fine aggregate, coarse aggregate, mineral filler and/or admixture if used and water, mixed in the proportions designed by the Engineer and in the manner set forth in this specification. On the basis of job and laboratory investigations of the proposed materials, the Engineer will fix the. proportions by weight of water, coarse aggregate, fine aggregate, cement, admixture and mineral filler where required, in order to produce concrete of the specified strength and workability. (14) Concrete Strength The concrete mix will be designed with the intention of producing a minimum average flexural strength (Modulus of rupture) of 600 pounds per square inch and compressive strength of 3000 psi at 7 days aftd/or a H day compressive strength of 3,600 pounds per square inch. The coarse aggregate factor (dry, loose volume of coarse aggregate per unit volume of concrete) shall not exceed 0.85. Unless otherwise shown on plans the concrete shall contain not less than six sacks of cement per cubic yard of concrete. The water -cement ratio t.(net gallons of water per sack of 94 pound cement) shall not exceed 6.0 gallons/sack. Concrete specimens shall be prepared, cured and tested as outlined in T.VD Bulletin C-11. V-14 a - (15) Workability of Concrete _ Concrete shall be uniformly plastic, cohesive and workable. Workable concrete is defined as concrete which can be placed without honey- comb and without voids in the surface of the pavement. workability shall be obtained without -producing a condition such that free water appears on the surface of the slab when being finished as specified. Where water appears on the surface of the concrete - after finishing and this condition cannot be corrected by reasonable adjustment in the batch design, the bleeding will be immediately corrected by one of the following measures or a combination of two or more of the following listed measures: (a) Redesign of the batch a (b) Addition of mineral filler to fine aggregate (c), increase of cement content In the event tha= the measures taken do not eliminate the bleeding immediately, concrete placement operations will be suspended, as directed to the Engineer, and will remain suspended, until such time as additional trial mixes demonstrate that a non -bleeding batch design has been achieved. Failing to achieve a satisfactory laboratory batch design the Contractor will be required to use different materials and to submit samples thereof for additional _ trial mixes and pilot bears as specified in THD Bulletin C-11. The mix will be designed with the intention of producing concrete which will have a slump of 1-1/2 inches when tested in accordance with THD Bulletin C-11. The slump shall not be less than 1 inch nor more than 3'inches. (16) Mix Design Prior to the beginning of concrete placement, and thereafter before any change in'source or characteristics of any of the ingredients except mineral filler, sufficient compression tests using various quantities of cement and aggregates proposed for use shall be supplied the Engineer for consideration. Piis:es will be designed and made in sufficient number to represent a wide range of water -cement ratios.. These mixes shall comply with the requirements herein prescribed for workability. From these preliminary tests the water -cement ratio required to produce concrete of the specified strength will be selected by the Engineer. The Contractor may at any time present in writing a suggested mix design and the Engineer will make the test necessary to determine its acceptability under these specification requirements. V-15 For mixing the concrete to be used in making the preliminary test specimens, the Contractor shall furnish and operate the .mixer approved for use on this project. A minimum one cubic yard batch shall be mixed or a batch of sufficient size to afford proper mixing, whichever is the greater. In lieu of the above mixer and procedure, the Contractor may furnish a portable mixer of sufficient rated capacity to mix a minimum three -sack batch; in which case, the batch mixed for the preliminary test shall not be less than the rated capacity of the mixer furnished. No additional compensation will be allowed for equipment, materials or labor involved in making preliminary test specimens. After the mix proportions and wa ter -cement ratio -required to produce concrete of the specified strength have been determined, placing of the concrete may be started. Type I cement shall have a specific surface area within a range of 1,600 to 1,900 square centimeters per gram. A change in the specific surface of the cement of more than 100 square centimeters per gram may require a new mix design. (17) Subgrade and Forms Preparation of Subgrade . Rolling and sprinkling shall be performed when and to the extent directed, and the roadbed shall be completed to or above the plane of the typical sections shown on plans and the lines and grades established by the Engineer. Drainage of the roadbed shall be maintained;;at all times. Sealed or treated subgrade cut in the preparation of the subgrade or setting of pavement forms shall be resealed or the subgrade restored to the original condition as directed by, -the Engineer. See Page V-24. The subgrade shall be maintained in a smooth, compacted condition in conformity with the required section and established grade until the pavement is placed and shall be kept thoroughly wetted down sufficiently in advance of placing any pavement to insure its being in a firm and moist condition for at least 2 inches below the pre- pared surface. Sufficient subgrade shall always be prepared in advance to insure satisfactory prosecution of the work. No equip- ment or hauling shall be permitted on the prepared subgrade, except by special permission of the Engineer, which will be granted only in exceptional cases and only where suitable protection in the form of two-ply timber mats or other approved material is provided. V-16 • (18) Placing and Removing Forms • The subgrade under the forms shall be firm and cut true to grade so that each form section when placed will be firmly in contact ' for its whole length and base width, and exactly at the established grade. Forms shall be staked with at least three pins for each 10-foot section. A pin shall be placed at each side of every joint. Form sections shall be tightly joined and keyed to prevent relative displacement. Forms shall be cleaned and oiled each time they are used. Forms shall be set for a sufficient distance in advance of the point where concrete is being placed to permit a finished and approved subgrade length of not less than 300 feet ahead of the mixing. Conformity of the grade and alignment of forms shall be checked immediately prior to placing concrete, and all necessary corrections made by the Contractor. Where any form has been disturbed or any ` subgrade becomes unstable, the form shall be reset and rechecked. In exceptional cases, the Engineer may require stakes driven to the grade of the bottom of the forms to support the equipment operated thereon and to withstand its vibration without springing or settle - went shall be required. If forms settle and/or deflect over 1/8 inch under finishing operations, paving operations shall be stopped and the forms shall be reset to line and grade. Forms shall remain in place for not less than 12 hours after the concrete has been placed. They shall be carefully removed in such a manner that little or no damage will be done to the edge of the pavement. Any damage resulting from this operation shall be imme- diately repaired. After the forms have been removed, the ends of all joints shall be cleaned, and any honeycombed areas pointed up with approved mortar. Immediately after pointing is complete, the form trench, if used, shall be filled with earth from the shoulders in such manner as to shed water from rainfall or curing away from the edge fo the pavement. On completion of the required curing, the sub - grade or shoulders adjacent to the pavement shall be graded in a condition to maintain drainage. Allowable grade revisions shall in no way affect the governing finishing and surface requirements of the completed pavement. All grade revisions shall be established by the Engineer. No additional payment over the contract unit price will be made for any pavement of a thickness exceeding that required on the plans as a result of adjustment of the forms. a. V-17 I. Concrete Mixing and Placing (1) Mixing The aggregates, mineral filler if required, cement and water shall be measured separately, -introduced into the mixer, and mixed for a period of not less than 50 seconds nor more than 90 seconds, measured from the time the last aggregate enters the drum to the time discharge of the concrete beings. The required water shall be introduced into the mixing drum during the first 15 seconds of mixing. The entire contents of the drum shall be discharged before any materials of the succeeding batch are introduced. The Engineer may increase the minimum mixing time to that necessary to produce thoroughly mixed.concrete based on inspection or appropriate uniformity tests. The mixing time may be varied at any time as necessary to produce acceptable concrete. If Ready -Mix concrete is used, the concrete shall be discharged into the specified hauling equipment and delivered to the road site. If truck agitators are used, the concrete shall be continuously agitated at not less than one nor more than six rpm as directed by the Engineer. The initial batch of concrete mixed after each time the mixer is washed out shall be enriched by additional mortar. The additional mortar shall be one sac- of cement and three parts of sand. (2) Placin? Any concrete not placed as herein prescribed within 30 minutes after mixing shall be rejected and disposed of as directed except as provided otherwise herein. Except by specific written authorization of the Engineer•,•concrete shall not be placed when the temperature is below 40 F, the temperature being taken in the shade and away from artifical heat. When such permission is granted, the Contractor shall furnish an approved enclosure, such as canvas -covered framework, to enclose and protect all pavement so placed, and shall maintain the temperature of the air surrounding the concrete at not less than 50 F for not less than 5 days. When concrete is being placed in cold weather, other than under the conditions stated above, the w V-18 11 .Contractor shall have available a sufficient supply of an approved covering material to.im,-ediately protect concrete if the air temperature falls to 32 F, or below, before concrete has been placed 4 hours. Such protection shall retain in place during the period the temperature continues below 32 F or for a period of not more than-5 days. Neither salt nor other chemical admixtures shall be added to'the concrete to prevent freezing. The Contractor shall be responsible for the quality and strength of concrete under cold weather conditions and any concrete damaged by freezing shall be removed and replaced at his expense. Concrete shall not be placed before sunrise and shall not be placed later than will permit the finishing of the pavement during sufficient natural light. Concrete shall be placed only on approved subgrade or subbase, and unless otherwise indicated on plans, the full width of the pavement shall be constructed monolithically. The concrete shall be deposited on the subgrade or subbase in such manner as to require as little rehandling as possible. Where hand spreading is necessary, concrete shall be distributed to the required depth by use of shovels. The use of rakes will not be permitted. Work- men will not be permitted to walk in the concrete with any earth or foreign material on their boots or shoes. The placing of concrete shall be rapid and continuous. • Concrete shall be distributed to such depth that when consolidated and finished, the slab thickness required by plans will be obtained at all points and the surface shall not, at any point, be below the established grade. Special care shall be exercised in placing and spading concrete against forms and at all joints to prevent the forming of honeycombs and voids. If in the opinion of the Engineer, the temperature, wind and/or _humidity conditions are such that the quality of the concrete will not be adversely affected, the specified placing time may be extended to a maximum of 45 minutes. (3) Reinforcing Steel All reinforcing steel, including steel wire fabric reinforcement, tie bars, and dowel bars shall be accurately placed and secured in position in accordance with details shown on plans. Reinforcing bars shall be securely wired together at alternate intersections, following a pattern approved by the Engineering, and at all splices, and shall be securely wired to each dowel intersected. When wire .fabric is used, it shall be securely wired together at all splices and to each dowel intersected. Tie bars shall be installed in the required position by the method -and device shown on plans or by approved method and device equivalent thereto. C-19 Tightly adhered scale or rust which resists removal by vigorous wire brushing need not be removed except that excessive loss of section to the reinforcement due to rust shall be caused for rejection. Excessive loss of section shall be defined as loss of section to the extent that the reinforcement will no longer meet the physical requirements for the size and grade of steel specified. Where plans require an assembly of parts at pavement joints, the assembly shall be completed, placed at required location and elevation, and all parts rigidly secured in required position by the method and devices shown on plans. Dowel bars shall be' accurately installed in joint assemblies in accordance with plans, each parallel to the pavement surface and to the centerline of the pavement, and shall be. rigidly secured in required position by -such means (as shown on plans) that will prevent their displace- ment during placing and finishing of the concrete. (4) Joints When the 'placing of concrete is stopped, a bulkhead of sufficient cross sectional area to prevent deflection, accurately notched to receive the load transmission devices or dowels if required, and shaped accurately to the cross section of the pavement shall be provided and installed as a back-up for the joint filler and rigidly secured in required position to permit accurate finishing of the concrete up to the joint. After concrete has been finished to the joint, formation of the joint seal space and finishing of the joint shall be executed. The back-up bulkhead shall remain in place until immediately prior to the time when concrete placing is resumed, when it shall be carefully removed in such manner that no element of the'joint assembly will be disturbed. The exposed portion of the joint assembly shall be free of adherent concrete, dirt or other material at the time placing of concrete is resumed. If necessary for proper installation of joint sealer, excessive spalling of -the joint groove shall be repaired to the satisfaction of. the Engineer in the manner which he prescribes. Careful workmanship shall be exercised in the construction of all joints to insure that the concrete sections are completely separated by an open joint or by the joint materials and to insure that the joints will be true to the outline indicated. (5) Weakened Plane Joints Weakened plane joints shall consist of transverse contraction joints and longitudinal joints and shall be formed or sawed as specified on the plans or as directed by the Engineer. When the joints are sawed, the saw shall be power driven, shall be manufactured .especially for the purpose of sawing concrete, and shall be capable V-20 of performing -the work. Saw blades shall be designed to make a clean smooth cut having a width and depth of cut as detailed on the plans. Tracks adequately anchored, chalk, string line or other approved methods shall be used to provide true alignment of the joints. The concrete saw shall be maintained in good operating condition and the Contractor shall keep.a.stand-by power saw on the project at all times when concrete operations are under way. If membrane curing is used, the portion of the seal which has been disturbed by sawing operations shall be restored by the Contractor by spraying the areas with additional curing seal. (6) Contraction Joints Transverse contraction joints shall be formed or sawed joints perpendicular to the centerline and surface of the pavement. Where sawed joints are used, contraction joints at approximately 15-f6ot intervals shall be sawed as soon as sawing can be accomplished without damage to the pavement and before 24 hours after the concrete has been placed, the exact time to be approved by the Engineer. The remaining contraction joints shall be sawed in a uniform pattern as directed by the Engineer, and they ' shall be completed before uncontrolled cracking of the pavement takes pla-ce. All joints shall be completed before permitting traffic to use the pavement. . (7) Longitudinal Joints Longitudinal joints shall be sawed when required by the plans from two -to seven days after construction of the pavement. Sawing shall not cause damage to the pavement and the groove shall be cut with a -minimum of spalling. No traffic (including construction traffic) shall be permitted on the pavement until the longitudinal ioint is cut. (8) Joint Sealers After the joints in the.hardened concrete have been repaired (if necessary) and cleaned to the satisfaction of the Engineer. The ' joints will be the filled with the W. R. Meadows sof-seal. After the sealant is installed it will effectively seal the joints against water, dirt and stones throughout repeated cycles of expansion and contraction. (9) Asphalt Board Premolded materials, wherever used, shall be anchored to the concrete on one side of the joint by means of copper wire or nails not lighter than No. 12 B S S gage. Such anchorage shall be sufficient to overcome the tendency of the material to fall out of the joint. V-21 (10) Spreading and Finishing All concrete pavement shall be consolidated by a mechanical vibrator. As soon as the concrete has been spread between the forms, the approved mechanical vibrator shall be operated to consolidate the concrete and remove all voids.. Hand manipulated vibrators shall be used for areas not covered by the mechanical vibratory unit. After finishing is complete and the concrete still workable, the surface shall be tested for trueness with an approved 10-foot steel straightedge. The straightedge shall be operated from the side of the pavement, placed parallel to the pavement centering and passed across the slab to reveal any high spots or depressions. The straightedge shall be advanced along the pavement in successive stages of not more than one-half its length. Practically perfect contact of the straightedge with the surface will be required, and the pavement shall be levelled to this condition, in order to insure conformity with the surface test required after the pavement has fully hardened. Any correction of the surface required shall be accomplished by adding concrete if required and by operating the longitudinal float over the area. The surface test with the straightedge shall then be repeated. After completion of the straightedge operation, the first pass of the burlap drag shall be made as soon as construction operations permit and before the water sheen has disappeared from.the surface. This shall be'followed by as many passes as required to produce , the desired texture depth. There shall be no unnecessary delays between passes. The drag shall be wet during use and maintained clean and free from encrusted mortar. It is the intent that the average texture depth resulting from the number of tests directed by the Engineer be not'less than 0.025 inches with a minimum texture depth of 0.020 inches for any one test. Should the texture depth fall below that intended, the finishing procedures shall be revised to produce the desired texture. The Contractor shall have available at all times hand brooms with stiff bristles for the purpose of providing textures when the pave- ment surface is in such a condition that the burlap drag or other methods being employed will not provide the desired texture. After completion of dragging and about the time the concrete becomes hard; the edge of the slab and joints shall be carefully finished as directed by the Engineer, and the pavement shall be left smooth and true to line. V-22 ' (11) . Protection of -Pavement and Bening to Traffic • The Contractor shall erect and maintain the barricades required by plans and such other standard and approved devices as will exclude public traffic and traffic of his employees and agents from the newly placed pavement for -the periods of time and -at locations hereinafter prescribed by the Engineer. Portions of the roadway, • or crossings of the roadbed required to be maintained open for' use by traffic; shall not be obstructed by the above required barricades. The pavement shall be closed to all traffic, including vehicles of the Contractor, until the concrete is at least 7 days old. This period of closure to all traffic may be extended if, in the opinion of the Engineer, weather or other conditions make it advisable to provide an extension of the time of protection. At the end of the 7 day period and.as long thereafter as ordered by the Engineer, and if so desired by the Contractor, the pavement may be opened for use by vehicles of the Contractor provided the gross weight (vehicle plus load) of such vehicles does not exceed 14,000 pounds. Such opening, however, shall in no manner relieve the Contractor from his responsibility for the work. on those sections of the pavement thus opened to traffic, all joints shall first be sealed, the pavement cleaned and earth placed against the • pavement edges before permitting vehicles thereon. After the concrete in any section is 14 days old, or as long thereafter as ordered by the Engineer, such section of pavement may be opened to all traffic'as required by plans or when so directed by the Engineer. On those sections of the pavement thus opened to traffic, all joints shall first be sealed, the pavement cleaned, earth placed against the pavement edges and all other work performed r as required for the safety of traffic. When High Early Strength Concrete, resulting from the use of Type III cement as'required by plans or special provisions, is used, the pavement may be opened to all traffic after the concrete is 7 days old; -or as long thereafter as ordered by the Engineer, subject to the same provisions.governing the opening after 14 days as above prescribed. UThere the Contractor desires to move.any equipment not licensed for • operating on public streets, on or across any pavement opened to traffic, he shall protect the pavement from all damage by means of two-ply timber mats of 2 inch stock or runways of heavier .material laid on a layer of earth, all as approved by the Engineer. V-23 The Engineer may require the opening of pavement to traffic prior to the minimum time specified above under conditions of emergency which in his opinion require such action in the interest of the public. In no case shall the Engineer order opening of the pavement to traffic within less than 72 hours afterthe last con- crete in the section is placed. The Contractor shall remove all obstructing materials, place earth against the pavement edges and perform other work involved in providing for the safety of traffic as required by the Engineer in ordering emergency opening. Orders for emergency opening of the pavement to traffic will be issued by the Engineer in writing. EARTH WORK A. Subgrade Preparation for curb .and gutter, streets, paving (asphalt and concrete) a1ley returns, alley paving, valley gutters, and earth work. Description Sub -grade preparation shall include the removal, haul and disposal of all obstructions, including existing curbs, gutters, paving mat- erials, base materials, concrete slabs and other obstructions shown on the plans or as designated by the Engineer and all scarifying, pulverizing, wetting, disking, blading and rolling with compactors to a.depth of at least G'.' gn.residential streets and to a depth of 19" on major thoroughfares and collector -streets. Compactors will be; used from the bottom ,to the finished sub -grade elevation -to compact the subgrade to 95% Standard Proctor Density (A.S.T.M. D-698) in conformity to the line, grade and sections as shown on the plans or as established by the Engineer. After the obstructions have been removed, or in conjunction with such removal, the street bed and/or alley return foundation and/or. sidewalk foundation shall be excavated and shaped in conformity with the typical sections and to the line and grades as shown on the.plans or as established by the Engineer. All unstable or otherwise objectionable material shall be removed from the subgrade and replaced with approved material. The excavation shall be don; in such a manner as to require a minimum of fill to bring the subgrade to the correct elevation. When the subgrade is too low as initially excavated, the contractor shall place additional soil or caliche in layers not exceeding four (4") inches and compact each laver by moistening and rolling. (1) Scraper Work The utilization of a scraper for excavation and shaping of subgrade and base is permitted with exceptions which are determined by depths of utility lines. Unless othe rMise specified by the engineer, the scraper shall not exceed 23 cubic yards capacity as rated loaded flush by the manufacturer. M V-24 (2) Compaction (See Section V, - Item 2 A ) The subgrade will be wetted and roller to secure 95% Standard Proctor Density. Before placement of the base and/or curb and gutter and/or concrete valley gutter and/or alley return slab and/or sidewalk, the subgrade will be checked by test rolling six (6) times or more if required by -the Engineer with a self-propelled roller weighing not less than 35 tons: Any soft of unstable spots ' found by test rolling will be corrected by removing the soft or unstable material and replacing it with suitable soil compacted to 95% Proctor Density. The areas so corrected shall be test rolled as specified above. (3) Intersection Special care shall be exercised in grading street intersections where dips are located so that the cross profiles present a smooth riding surface and so that the compacted base thickness will not be less than six (6") or nine (9"). Crown section shall begin to decrease 60 feet back of end of radius for residential streets. For wider streets dips will be blue topped as shown on the detail sheet. (4) Prosecution of the Work The contractor may proceed with subgrade preparation on any schedule he may select except that, unless hindered by factors beyond his control, not more than seven (7) calendar days shall elapse between the time subgrade preparation is begun and the spreading and compacting of the caliche base. Measures shall ' be taken by the contractor not to leave driveways impassable during the night hours. (5) Excess Materials Materials excavated in excess of that needed in fill and backfill behind curb and shall be wasted by the contractor. Care shall be taken by the -contractor to use only topsoil in the backfill behind the curbs. The contractor -may dispose of the surplus excavated material in. any manner not objectionable to the public, -and it is his responsibility to located a suitable site for dumping the waste excavation. In any event, the contractor shall not dispose of the surplus materials in any of the lake areas either outside or within the city limits. Location of disposal sites near any lake area must be approved by the Engineer. V-25 L . (6) Subgrade for Alley Paving (See page IV-24),. The preparation of the subgrade for concrete alley paving shall be done in the same manner as other subgrade excavation which requires scarifying, wetting, disking, blading, rolling, and compacting. The contractor will be required to excavate around existing improvements such as gas meter, water meters, poles, etc. Each of these obstructions shall: be the responsibility of the Contractor. Trees that conflict -with the improvements shall , be removed by the contractor upon approval of the engineer. The contractor shall shape to subgrade for the cross-section shown on the plans and to the lines and grades established by the engineer. After the forms are set and before the reinforcing is placed the contractor shall finally shape the subgrade so that there'will be a minimum thickness of concrete of five (5") inches at the centerline and seven and one-half incyes (7-1/2") inches at the outside edges. All areas where fill material is required shall be compacted. The subgrade shall be wetted and rolled to secure 90% Proctor Density in the upper six (6") making a -firm foundation for the alley paving. The contractor will be required to shape the portion of the alley outside of the limits of the concrete slab so that all drainage in the alley will be to the invert of the concrete slab. Excess excavated materials shall be hauled to any approved location. B. Embankment Description Prior to placing any embankment, all "Preparing Right -Of -Way" and/or "Clearing and Grubbing" operation shall have been completed on the excavation sources and areas over which the embankment is to be placed. Stump holes or other small excavations in the limits of the embankments shall be backfilled with suitable material and thoroughly tamped by approved methods before commencing embankment construction. The surface of the ground, including.plowed loosened ground, or surface roughened by small washes or otherwise, shall be restored to approximately its original slope by blading or other methods and, where indicated on plans or required by the engineer, the ground surface thus prepared shall be compacted by sprinkling and rolling. Where embankments are to be placed adjacent to or over existing e roadbeds, the roadbed slopes shall be plowed or scarified to a depth of not less than six (6") inches and the embankment built up in successive layers, as hereinafter specified, to the level of the old roadbed before its height is increased. 'Then, if directed, the top of the old roadbed shall be scarified and recompacted with the next. layer of the new embankment. The total depth of the scarified and added material shall not exceed the permissable depth of layer. V-26 • Trees, stumps, roots, vegetation, or other unsuitable materials shall not be placed in embankment. Except as otherwise required by the plans, all embankment shall be constructed in layers approximately parallel to the -finished grade of the roadbed and unless otherwise specified each layer shall be so constructed as to provide a uniform slope of 1/4" inch per foot from the center line of the roadbed to the outside. Embankments shall be constructed to the grade established by the engineer and completed embankments shall correspond to the general shape of the typical sections shown on the plans and each section of the embankment shall -correspond to the detailed section or slopes established by the engineer.. After completion of the road- way, it shall be continuously maintained to its finished section ' and grade until the project is accepted. Except as otherwise specified, earth embankments shall be ` constructed in successive lavers for the full width of the individual roadway cross section and in such lengths as are best suited to the sprinkling and compaction methods utilized. Layers of embankment may be formed by utilizing equipment which will spread the material as it is dumped, or they may be formed by being spread by blading or other acceptable methods from piles or windrows dumped from excavating or hauling equipment.in such amounts that Material is evenly distributed. Minor quantities of rock encountered in constructing earth embank- ment shall be incorporated in the specified embankment layers, or may be placed in accordance with the requirements for the construction of rock embankments in the deeper fills within the* • limits of haul shown on the plans, provided such -placement of rock is not immediately adjacent to structures. Also, rock may be placed in the portions of embankments outside the limits of the completed roadbed width where the size of the rock prohibits their incorporation in the normal embankment layers. Each layer -of embankment shall be uniform as to material, density and moisture content before beginning compaction. Where layers of unlike materials abut each other, each layer shall be feather - edged for at least 100 feet or the material shall be so mixed as to prevent abrupt changes in the soil. No material placed in the embankment by damping in a pile or windrow shall be incorporated in a laver in that position, but all such piles or windrows shall be moved by blading or similar methods. Clods or lummps of material V-,2 7 shall be broken and the embankment material mixed by blading, disking, or similar methods to the end that a uniform material or uniform density is secured in each layer. t•?ater required for sprinkling to bring the material to the moisture content necessary for maximum compaction shall be evenly applied and it shall be the responsibility of the .contractor to secure a uniform moisture content throughout the layer by such methods as may be necessary. In order to facilitate uniform wetting of the embankment material, the contractor shall water at the material source if the sequence and methods used are such as not to cause an undue waste of water. Such procedure shall be subject to the approval of the engineer. (1) Compaction The compaction method shall require that each layer shall' be compacted to the required density by any method, type., and size of equipment which will give the required compaction. The depth of layers, prior to compaction, shall depend upon the type of sprinkling and compacting equipment used. Prior to and in conjunction with the rolling operation, each layer shall be brought to the moisture content necessary to Obtain the required density and shall be kept leveled with suitable equipment to insure uniform compaction over the entire layer. For each layer of earth embankment and select material, it is the intent of this specification to provide the density as required herein, unless otherwise'shown on the plans. The required compaction shall be 95% Standard Proctor Density A.S.T.M D-698. After each section of earth embankment or select material is complete, tests as necessary will be made by the engineer. If the material fails to meet the density specified, the course shall be reworked as necessary to obtain the specified compaction, or the compaction method shall be altered on subsequent work to obtain specified density. Such procedure shall be determined by, and subject to, the approval of the engineer. At any time, the .Engineer may order proof rolling to test the uniformity of compaction of the embankment subgrade. All irregularities, depressions, weak or soft spots which develop shall be corrected immediately by the contractor. Should the subgrade,.due to any reason or cause, lose required stability, density, or finish before the pavement structure is ` placed, it shall be recompacted and refinished at the sole expense of the contractor. Excessive loss of moisture in the subgrade shall be prevented by sprinkling, sealing,.or covering ' with a subsequent layer of granular material. Excessive loss of moisture shall.be construed to exist when the subgrade soil moisture content is more than 4 percent below the optimum for compaction to Standard Proctor Density. (Also see Section t, Item 2 [A] Compaction.) ° s At Culverts Embankments adjacent to culverts which cannot be compacted by { use of the blading and rolling equipment used in compacting the adjoining sections -of embankment shall be compacted in the manner prescribed below. The following requirements shall apply to the backfilling of pipe culverts in addition to the pertinent portions of the general requirements given in the preceding section. After the bedding has been prepared and the pipes installed as required by the pertinent specifications, selected materials from excavation or borrow shall be placed along both sides of the pipe equally, in uniform layers not to exceed six (6") inches in depth (loose measurement), wetted and thoroughly compacted so that on each side of the pipe there shall be a berm of thoroughly compacted materials at least as wide as the external diameter of the pipe, except insofar as undisturbed material obtrudes into this area. The method and degree of compaction shall be same as specified above. Filling and/or backfilling shall be continued in this manner to the elevation of the top of the pipe. Special care shall be taken to secure thorough compaction of the material placed under the haunches of the pipe. All fill or backfill below the top of the pipe shall be compacted mechanically in the manner and to the density pre- scribed above; regardless of whether or not such material is . placed within the limits of the embankment or roadbed. In the case of embankments, the remainder of the fill above the top of pipe shall be placed in accordance with the provisions fof placing roadway embankment as prescribed in the pertinent specifications included in the contract. No construction traffic will be permitted to cross any pipe culvert until the specified minimum depth of fill above the pipe has been placed and consolidated in accordance' with these provisions. 3. BASE COURSE The base course.shall consist of a minimum of six (611) or nine (9") inches of compacted approved caliche, black base or combination of caliche and black base material shaped in --accordance with the typical cross - sections provided in the plans and to the grades established by the Engineer. V-29 4 A. Hauling and Placing Approved base material shall be hauled in vehicle nf. uniform capacity to the site and dumped evenly so that an ada- quate quantity of material will be placed to provide a minimum of six (6") inches of compacted ease material on all units except major thoroughfare streets. On these'streets the contractor will construct nine (9") inches of compacted base material. B. Processing Processing shall be accomplished in multiple lifts of three (3") inches in compacted depth. Each lift or layer shall be thoroughly moistened and rolled as it is cut from the windrow. After all of the material is cut from the windrow to the sides, it shall be cut back to the center in lifts of three (3") inches 'and thoroughly moistened and rolled again. Succeeding layers shall then be placed similarly until the caliche base course is completed and 95% Proctor Density has been attained. All nine (9") inches compacted caliche base shall be accomplished in three (3") inch lifts. The caliche course shall then be sprinkled as required and rolled with compactors as directed until a uniform compaction of 95% of "Standard Proctor Density" is secured. Throughout this entire operation, the shape of the course shall be maintained by blading; and the surface.upon completion shall. besmooth -and in conformity with the typical sections shown on plans and to the established lines and grades. Processing of asphaltic base shall be as directed by the Engineer and similar to that described under Hot Mix Asphaltic Concrete Surface. Lift thickness will be indicated by the Engineer or as shown on the paving plans: Electronic screed controls will be _ required for placing black base on grade. The density required will be determined by the Engineer after material to be used has been approved. ,All areas and "nest" of segregated course or fine material shall be corrected or removed and replaced with well graded material as directed by the Engineer. Each layer of black base will be test rolled six (6) times with a 35 ton roller and approved by the Engineer before succeeding layers,are placed. A delay in construction of the next succeeding layer of black base caused by rain, snow, etc. will require re -rolling and approval prior to construction of the next layer.. L V-30 T The utiliziation of the traffic to compact and bind the base 'is an essential part of the construction, and wherever possible s= the base course shall be opened to traffic, and the contractor - shall direct and distribute the traffic uniformly over the entire width of the base course. During the period of at least seven (7) days that traffic is being directed over the base, the caliche base shall be satisfactorily maintained by the use of water trucks, blades, drags and such other equipment as is required. The base course shall be so maintained until the wearing surface is placed thereon. The 'surface shall not be placed on base course that exceeds optimum moisture by two (2%) two per cent. C. Finishing Description The compacted base shall be finished and shaped immediately preceding the application of the surface treatment. All loose or unconsolidated material shall be removed and the surface moistened and rolled with a steel wheel roller. All irregularities, depres- sion or weak spots which develop during compaction shall be corrected by scarifying the areas affected, adding or removing material as required, reshaping and recompacting by sprinkling and rolling. (1) Weak Spots in Base or Subgrade The finished base shall.be checked by a minimum of six (6) test rollings with a 35 ton roller. Any weak spots found shall be remedied before the surface is applied. The weak spots may be remedied by reprocessing the area in which the weak spot is found in which case the base will be allowed to cure for 72 hours before the surface is applied. If the contractor chooses, he may repair the weak spot by removing the material involved and replacing it with type "C" hot mix or asphalt stabilized base. In this case the surface may be applied as soon as the hot mix patch has been compacted and cooled to ambient.temperature. (2) Allowable Deviation in Finish Immediately prior to placing of surfacing, the base shall be checked and any deviation in excess of three -eights (3/8) inch from the established grade or true cross section shall be corrected as provided above for defects. Longitudinally a straight edge 10 feet long shall be used to detect any deviation which shall be corrected as defects. V-31 n r N -4. HOT MIX ASPHALTIC CONCRETE SURFACE A. Description This item shall consist of 1'-1/2" compacted T.H.D. Type "Cr' hot mix asphaltic concrete surface, using approved crushed stone aggregate, constructed over a compacted base. The base shall be primed and a tack coat applied as required. (1) General (Test Method Ter,-207-F It is the intent of this specification that the material be . placed and compacted to a density of 95 to 100 percent of that density developed in the laboratory test method of molding stability specimens with a minimum compacted thickness of one and one half inches (1-1/2"). Sufficient density- tests will be made in order to determine that the compaction procedure used by the contractor is adequate and proper to accomplish the intent as stated above. If the mixture produced does not have the specified qualities, it shall be changed until it does. The pavement shall be constructed on the previously completed and approved subgrade, base, existing pavement, bittrninous surface or in the case of a bridge, on the prepared floor slab, as herein specified and • in accordance with the details shown.on the plans. r The contractor will not be allowed to place the A.C. surface when the ambient'terperature is 55p.F or -less and wind velocity exceeds 10 miles per hour'. The contractor may apply the A.C. paving surface when the ambient temperature is 550F or above and wind velocity is equal to or less than 10 miles per hour or when the ambient' temperature is 60OF or above 'regardless of wind velocity. The engineer may use his discretion to require a cover over the asphaltic mixture when being hauled from the plant to the job site. If the temperature of a load of asphaltic concrete measured while passing through the lay -down machine is 25 degrees F less than the mixing temperature, the load may be rejected by the Engineer and payment will not be made for the -rejected material. (2) Preparation of Base and Areas Borderinj The compacted base upon which the hot mix asphaltic concrete surface is to be placed shall be prepared and cleaned, as required by the Engineer, before the prime coat is applied. V-32 i it (3) Prime Coat The prime coat shall consist of an application of .25 gallons per square yard of MC asphalt. (4) Tack Coat Before the asphaltic mixture is laid, the surface upon which the tack coat is to be placed shall be cleaned thoroughly to the satisfaction of the engineer. The surface shall be given a uniform applieation'of tack coat using asphaltic materials of this specification. This tack coat .shall be applied, as directed by. the engineer, with an approved sprayer. Where the mixture will adhere to the surface on which it is to be placed without the use of a tack coat, the tack coat may be eliminated by the engineer. All contact -surfaces of curbs and structures and all joints shall be painted with a thin uniform coat of the asphaltic material meeting the requirements for tack coat. The tack coat shall be'rolled with a pneumatic tire roller as directed by the engineer. (5) Transporting Asphalt Concrete The asphaltic mixture, prepared as specified above shall be hauled to the work site in tight vehicles previously cleaned of all foreign .material. The dispatching of the vehicles shall be arranged so that all material delivered may be placed, and all rolling shall be completed during day -light hours. The inside of the truck body may be given a light coat of oil, lime slurry or other. material satisfactory to the Engineer, if necessary, to prevent mixture from adhering to the body. In cool weather or for long hauls, canvas covers and insulating of truck bodies may be required vehicles of the semi -trailer type are prohibited. (6) Placing Generally the asphaltic mixture shall be -dumped and spread on the approved prepared surface with the specified spreading and finishing machine in such manner that when properly compacted. the finished pavement will be smooth, of uniform density and will meet the requirements of the typical cross sections and the surface tests. During the application of asphaltic material, - care shall be taken to prevent splattering of adjacent pavement, curb and gutter, and structures. V-33 The surface course shall be laid in a compacted layer with a minimum compacted thickness of one and one half inches (1-1/2"). A level -up course, 1/2" or more in thickness, shall require the use of black base or acoarse grade of hot mix approved by the engineer. It shall be spread and compacted to lines and grades as established by the engineer. When the asphaltic mixture is placed in a narrow strip along the edge of an existing pavement, or used to level up small areas of an existing pavement or placed in small irregular areas where the use of a finishing machine is not practical, the finishing machine may be eliminated when authorized by the engineer, provided a staisfactory surface can be obtained by other.approved methods. Flush structures, adjacent to flush curbs, gutters, linears and structures, the surface shall be finished uniformly high so that when -compacted it will be slightly above the edge of the curb and- <' flush structure. Joints. A11 joints shall present the same texture density, and smoothness as other sections of the course. The joints between old and new pavements or between successive day's work shall be carefully made to insure a continuous bond between old and new sections of the course. a The transverse edges of old pavement and, if required by the engineer, the successive days pavement'shall be sawed with an approved concrete saw to -expose an even vertical surface for the full thickness of the course. All contact surfaces of previously constructed pavement shall be painted with a thin uniform coat of hot bituminous material before the fresh mixture is placed. (i) Compacting As directed by the engineer, the pavement shall be compacted thoroughly and uniformly to the required density. The specified rollers shall be used, except as provided in paragraph (3) below. Rolling with the three wheel and tandem rollers shall start longitudinally at the sides and proceed toward the center of the pavement, overlapping onsuccessive.trips by at least half the width of the rear wheels unless otherwise directed by the engineer. Alternate trips of the roller shall be slightly different in length. on super -elevated curves, rolling shall begin at the low side and progress toward the high side unless otherwise directed by the engineer. Rolling with pneumatic roller shall be done as directed by the engineer. Rolling shall be continued until required compaction is obtained and all roller marks are eliminated. One tandem roller, two pneumatic rollers and at least one three wheel roller, as specified above, shall be.pro- vided for each job. Additional rollers shall be provided if V-3= needed. The motion of the roller shall be slow enough at all times to avoid displacement of the mixture. If any displacement occurs, it shall be corrected at once by the use of rakes and of fresh mixture where required. The roller shall not be allowed to stand on pavement which has not been fully compacted. To prevent adhesion of the surface mixture to the roller, the wheels shall be kept thoroughly moistened with water, but an excess of water will not be permitted. All rollers must be in good mechanical condition. Necessary precautions shall be taken to prevent the dropping of gasoline, oil, grease or other foreign matter on the pavement, either when the rollers are in operation or when standing. When indicated on the plans or permitted by the engineer. in writing, the pavement may be compacted to the required density by the use of compacting equipment other -than that specified herein. Hand tamping. The edges of the pavement along curbs, headers and similar structures, and all places not accessible to the roller, or in such positions as will not allow thorough compaction with the roller, shall be thoroughly compacted with lightly oiled tamps. Rolling with the trench type roller will be required on widening areas in.trenches and other limited areas where satisfactory compaction cannot be obtained with the three wheel and tandem rollers. (8) Surface Tests' The surface of the pavement, after compaction, shall be smooth and true to the established line, grade and cross section, and when tested with a 10 foot straight edge placed parallel to the center- line of the roadway or'tested by other equivalent and acceptable means, except as provided herein, the maximum deviation shall not exceed 1/8 inch in 10'feet, and any point in the surface not meeting this requirement shall be corrected as directed by the engineer. kT^en placed on existing surfaces, the 1/8 inch deviation in 10 feet 1 requirement may be waived by the engineer. (9) Surface Density Test See Section IV, Item 10-D. Laboratory Control. (10) Equipment Spreading and Finishing Machine. The spreading and finishing machine shall be of a type approved by the engineer, shall be capable of producing a surface that will meet the requirements of the typical cross section and the surface test, when required, and shall have adequate power to propel the delivery vehicles in a staisfactorymanner when the mixture is dumped into the finishing miachine. The finishing machine shall be equipped faith a flexible spring and/or hydraulic type hitch sufficient in design and capacity to maintain contact -between the rear wheels of the hauling V-35 equipment and -the pusher rollers of the finishing machine while the mixture is being unloaded: The finishing machine shall be operated in a low gear, or as directed by the engineer, at a speed to produce a surface that will meet the requirements of the typical cross section and surface test. Any vehicle which the finishing machine cannot push or propel in such a manner as to obtain the desired lines and grade without resorting to hand finishing will not be allowed to dump directly into the finishing machine. Vehicles dumping into. the finishing machine can be mechanically and/or automatically operated in such a manner that overloading the finishing machine being used cannot occur and the required line and grade will be obtained . without resorting to hand finishing. Dumping of the asphaltic mixture in a windrow and then placing the mixture in the finishing machine with loading equipment will be approved by the Engineer, provided that the loading equipment is constructed and operated in such manner that substantially all of the mixture deposited on the roadbed is picked up and placed in the finishing machine without contamination by foreign material of the mixture. The loading equipment will be so designed and operated that the finishing machine being loaded will obtain the required line, grade and surface without resorting.to hand finishing. Any operation of the loading equipment resulting in the accumulation and subsequent shedding of this accumulated material into the asphaltic mixture will not be permitted. Forms. The use of forms will not be required except where necessary to support the edges of the pavement during rolling. If the pavement will stand rolling without undue movement, binder twine or small rope may be used to align the edges. Motor Grader. The motor grader, if used, shall be self-propelled power motor grader; it shall be equipped with pneumatic tired wheels; shall have a blade length of not less than 12 feet; shall have a wheel base of not less than 16 feet; and shall be tight and in good operating condition and approved by the engineer.

A.11 tires of the .-same roller shall be smooth tread -of equal sie and diameter and shall be arranged in such.a manner that the gap between the tires of one axle will be covered by the tires of the other. The tire pressure of each tire shall be adjusted as directed by the engineer and this -pressure shall not vary by more than S pounds per square inch. Two Axle Tandem Roller.- This roller shall be an acceptable' poker driven tandem roller weighing not less than 8 tons. Three Wheel' Roller. This roller shall be an acceptable power driven three wheel roller weighing not less than 10 tons. Trench Roller. This roller shall be an acceptable power driven trench roller equipped with sprinkler for keeping the wheels wet and adjustable road wheel so that roller may be kept level.during rolling. The drive wheel shall be not less than 20 inches wide. The roller under working conditions shall produce 325 pounds per linear inch of roller width and be so geared that a speed of -1.8 miles per hour is obtained in,low gear._ Straightedges and Templates.. +'hen directed by the engineer, the contractor shall provide acceptable 10 foot straightedges for • surface testing. Satisfactory.templates shall be provided as required by the engineer. A11 equipment shall be maintained in good repair and operating condition and shall be approved by the engineer. The Contractor shall furnish such suitable machinery, equipment, a and construction forces as may be necessary, in.the opinion of the Engineer, for the proper prosecution of the work, and failure to. do so may cause the Engineer to withhold all estimates which have or may become due or the Engineer may suspend the work until his requests are complied with. (11) Opening to Traffic The pavement shall be opened to traffic when directed by the engineer. All construction traffic allowed on the pavement " shall comply with City Ordinance governing traffic on City Streets. If the surface ravels, it will be the contractor's responsibility to correct this condition at his expense. V-37 5. CLEANUP Within three days after completion of any Sub -Unit of paving the contractor shall clean, remove rubbish and temporary structures from the street, restore in an acceptable manner all property, both public and private, which has been damaged during the prosecution of the work, and leave the site of the work in a neat and presentable condition throughout. The cost of the "cleanup" shall be included as a part of the cost of the various items of work involved, and no direct compensation will be made for this work. This work shall be done before final acceptance of the Sub -Unit will be considered. The cleanup shall include the sloping, filling and shaping of the area between the curb and property line. This area shall be ,filled with good top soil. When the ground behind the curb is higher than the top of the curb, the Contractor will be required to cut this area ' down to provide a smooth, even slope between the property line and the curb. 6. .PROTECTION OF EXISTING UTILITIES A. Adiustment of Valves and Manholes The City Forces will place valve boxes and manholes on finished grade after the base has been finished to grade. The Contractor • shall allow the City Forces at least 3 days to do this work after finishir_g•the base and before application of asphalt. It shall be , the responsibility of the Contractor to notify the Public Works Department 48 hours after curb and gutter has been completed so that the City Forces can'properly schedule their work. In all alleys the City Forces will set the valve boxes and manholes to grade after the forms are in place. Any variation in this procedure that causes expense to the City shall have the approval of the Engineer, and such expense shall be borne by the Contractor. B. Installation, Adjustments, and Protection of Utilities and Traffic Installations r The plans show only approximate locations of utilities as obtained from the various utility companies and shall not relieve the Contractor from familiarizing himself with all -underground utilities. It is not implied that all existing utilities are shown on the plans. The City of Lubbock does not assume any responsibility for any utility lines which are not shown on the plans. The utility companies will attempt to move all utilities that can be reasonably removed prior to beginning of construction; however, this does not relieve the Contractor from any damage that he might do to any utility property. In case of any damage, the Contractor shall immediately notify the affected utility company. -38 City Water and Sewer 762-6411; Ext. 2595 . Lubbock Power and Light 762-6411, Ext. 2554 City Traffid Shop 762-6411,-Ext. 2140,2144 Ener Gas Traffic Shop 74T-4240 ' Southwestern Public Service 763-2381 Southwestern Bell Telephone 741-6101 Cox Cable of Lubbock 793-2222 City Traffic Engineering 762-6411, Ext. 2132 Sequence: The sequence of utility adjustments has been mutually agreed upon by the utility companies in the City of Lubbock and will attempt to follow the following schedule: Plans for contract projects will be delivered to all utility companies two weeks prior to opening bids. As a general rule, .these projects will have been staked. The utility companies will relocate all items necessary, locate and flag all meters, valves, manholes, underground cables, etc., prior to the date the Contractor is to begin construction. After the subgrade is completed on alley paving projects, and after the base is completed onall street paving projects, all manholes, valve boxes, etc., will be set to finished grade by the utility companies. The site shall be left in a clean condition. On all projects, including private contracts, the Contractor shall exercise care not to damage any sanitary sewer pipe or manholes, storm sewer pipe or manholes, or telephone cable or manholes, water or gas lines, valve boxes, meter boxes, nor any other pipe or utility. If necessary; the Contractor shall call the department or company concerned and make arrangements for adjusting the manhole, valve box, meter box, or other utility to grade. On all projects for which he is awarded a contract, the Contractor will be responsible during the construction period for any damages to manholes, valve boxes, meter•boxes, and other utilities. Should any item be damaged during the process of construction, the Contractor is to notify the affected utility company and the City inspector. The utility company will immediately repair the damaged item. Any bills for damage will be sent through the Department of Engineering. The Department of Engineering will process all bills and fix responsibility for damage and govern the extent of repair. V-39 e f Private contracts do not have plans, but utility companies will r be furnished cut sheets and notified of impending construction by letter. Other items such as adjustments, damages, etc., will be handled the same as for bid let projects. The utility companies will schedule their work with the Contractor.
