If the Contract or the Architect cannot agree on a revised amount, the Architect will promptly issue a Certificate for Payment for the amount for which he is able to make such representations to the Owner. The Architect may also decline to certify payment or, because of subsequently discovered evidence or subsequent observations, he may nullify the whole or any part of any Certificate for Payment previously issued, or the Owner may withhold or nullify the whole or part of any Certificate of Payment, to such extent as may be necessary to protect the Owner from loss because of. a s, r r 1. defective work not remedied, 2. - third party claims filed or reasonable evidence indicating probable filing of such claims, 3. failure to the Contractor to make payments properly to subcontractors, or for labor, materials, or equipment, 4. reasonable evidence that the work cannot be completed for the unpaid balance of the Contract Sum, 5. damage to the Owner or another contractor, 6. reasonable evidence that the work will not be completed within the Contract time, 7. persistent failure to carry out the work in accordance with the Contract Documents, or 8. failure to comply with contractual obligations to meet all federal requirements concerning labor standards.

In case the Surety should fail to commence 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 enjoy such force of men and use of machinery, 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.

When the work shall have been substantially completed, the Contractor and his Surety shall be so notified and certificates of completion and acceptance, as provided in Section 57 hereinabove set forth, shall be issued. A complete itemized statement of the Contract accounts, certified by the Owner's F4resentative as being correct, shall then be prepared and delivered to the 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 sixty days after the date of certificate of completion. f. .

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 65 supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety.

The Architect shall 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 retained by the Owner under the terms of this Agreement, and shall certify same to the Owner's Representative. If the Owner's Representative finds the statement to be satisfactory, he shall submit it 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. 66.

Aggregate for concrete construction proposed to be used in this project shall have a loss not to exceed 18% when subjected to 5 cycles of the Magnesium Sulfate soundness test ASTM C-88. Stockpiles The location of all stockpiles of aggregate shall be approved by the Engineer prior to unloading as to zoning requirements, smoothness and compaction of the ground, and traffic conditions. Stockpiles of aggregate to be incorporated into the project shall be protected from dust r" by drift fences of any suitable material approved by the Engineer, when sandstorm possibilities exist. Care will be taken to prevent dusty conditions in the stockpile area from any sources. E, 7 M-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 test certificates 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 mix design and the result of compression tests made by a- -- commercial laboratory. 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 The Engineer shall approve the mix design after the pre - construction tests have been completed. 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 ASTM C-31. The specimens shall be cured under standard moisture and temperature conditions in accordance with 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. Strength tests on Class ,C° Concrete shall be made for approximately each 30 cubic yards, or every third truck on each day's run. 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 standardtest cylinders made from a composite sample obtained in accordance with the 'requirements of ASTM C-172. Two of the cylinders shall be tested at 3 or 7 days and 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 M-2 s manifest evidence of improper sampling, molding, or testing, 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. r # The results of -the 3 or 7 day strength tests will be compared with the 3 or 7 day strength of the preconstruction C 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 r concrete and the exact location in the work at which each load represented by'a strength test is deposited. C E.

Samples of the completed pavement shall be removed from locations designated by the Engineer to enable him to determine the composition, compaction, and density of the pavement. Samples for each day or fraction thereof shall be taken by City personnel. The Contractor shall replace the pavement removed from core holes at no cost to the City. If the pavement is deficient in composition, compaction, or thickness, satisfactory correction shall be made as directed by the Engineer. Tests on Marshall specimens shall be made twice daily or as directed by the Engineer to retain job control. The mixture shall comply with the requirements of Table (2) above when tested in accordance with the Marshall method procedures contained in Chapter III of the Asphalt Institute's Manual Series No. 2 (MS-2), current addition. If the laboratory stability and/or field tests of the M-34 t. 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/field tests 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 discontinued 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 of the mixing plant. Any operation that has tendency to segregate the mixture or 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 system fails to meet the asphalt specifications or gradation requirements, then the total contents of the silo storage system shall be condemned. 12. BARRICADES AND SIGNS 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.

The Contractor shall maintain each barricade in a neat 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 r open to traffic all necessary Regulatory, Warning and Guide signs shall be in place. r Signs required by temporary conditions or restrictions shall be removed immediately when those conditions cease to exist or r., the restrictions are withdrawn. Guide signs directing traffic j to and on temporary routes or detours shall be removed when no ` longer applicable. Standardization is important with respect to design and placement, and uniformity of application is equally important. Identical conditions should always be marked with the same type of sign, regardless of where those particular conditions occur. 7 M-35 All signs that are to convey their message during hours of darkness shall be reflectorized or illuminated. Signs for daytime use only may be non-reflectorized but a fluorescent background material will be used for increased daytime visibility if requested by the Engineer. Where there is serious interference from extraneous light sources, and a reflectorized 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 above. 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 will be made, unless indicated 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 the beginning and end of the construction area. M-36 DETAILS OF CONSTRUCTION 1. CONCRETE r A. CURB AND GUTTER (CLASS A -CONCRETE) Description This item shall consist of Portland Cement 24" concrete curb and gutter or 24" 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 Openincrs 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 anddeterminethe 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 1466 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'sapproval as to driveway widths and location, in addition to the section, and line and grade approval before any pour is started on any curb and gutter unit. 2. Excavation and Subcrade Excavation for the curb and gutter shall be made with the excavation 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 compacting to 95t Standard Proctor Density (ASTM 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 immediately be relocated behind the proposed curb and gutter by the Contractor. ,,, D-1 3. Setting Forms Forms for concrete 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. 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 floated 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. 5 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 no.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. 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 D-2 rcontinuous grade down tF el flo: w-line the length of the gutter. Curb and gutter shall be finished uniformly by wood troweling to an accurate cross-section. Extra water will not be added for finishing. 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 section shall present a uniform appearance without "waves" in the face of the curb or "pockets" in the gutter. Concrete shall not be poured during sand storms. Concrete shall be protected to maintain temperature 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 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 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.

Where prefabricated wire mats are specified or permitted, the wire shall be cold worked steel wire conforming to the requirements of ASTM A-496, except that steel shall be made by open-hearth, electric-furnace,,or basic oxygen processes. The prefabricated wire mats shall conform to the requirements of ASTM A-497. Mats that have been bent or wires dislocated or parted during shipping or project handling shall be realigned to within one-half inch of D-12 r the original horizontal plane of the mat. Mats with any portion of the wires out of vertical alignment more than r. one-half inch after realignment and/or wires dislocated or mutilated so that, in the opinion of the Engineer, they do not represent the original mat, shall be rejected. The mats may be clamped or wiredlso 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. When fabricated steel bar or rod mats are specified, the .., mats shall meet the requirements of ASTM A-184. 10. Mechanical Vibratory Equipment All concrete placed for pavement shall be consolidated by approved mechanical vibrators 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 a manner as to not interfere with the transverse or longitudinal joints. Separate vibratory units shall be operated at 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 per 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 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. D-13 Complete and satisfactory consolidation of the concrete pavement is 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. 11. Finishing Machine -Finishing. All concrete pavement shall be finished mechanically with approved power -driven machines, except as herein provided. Hand -finishing will be permitted on the transition from a crowned section to a superelevated section without crown or curves, and on straight line superelevation sections less than 300 feet in length. Hand -finishing will also be permitted on that portion of a'widened pavement outside the normal pavement width, on sections where the pavement width is not uniform, or required monolithic widths are greater than that of available finishing machines. Machine -finishing of pavement shall include the use of power'- driven spreaders, power -driven vibrators, power - driven transverse strike -off, and screed, or such alternate equipment as may be substituted and approved by the Engineer. All concrete 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. The transverse finishing machine shall first be operated to compact and finish the pavement to the required section and grade, without surface voids. The machine shall be operated over each area as many times and at such intervals as directed.At least two trips will be required and the last trip over a given area shall be a continuous run of not less than 40 feet. -After completion of finishing with the transverse finishing machine a'transverse drag float may be used. The consistency of the concrete as placed should allow the completion -of all finishing operations without the addition of water to the surface. When field conditions are such that additional moisture is needed for the final concrete surface finishing operation, the required water shall be applied to the surface by fog spray only and shall beheld to a minimum. D-14 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 centerline and passed across the slab to reveal any high spots or depression. The r` 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 leveled to this condition, in order to insure conformity " with the surface test required below, 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. For one -lane pavement placement and uniform widening, the equipment for machine -finishing of concrete pavement shall be as directed by the Engineer but shall not exceed the requirements of these specifications. After completion of the straightedge operation, as soon as construction operations permit, texture shall be applied with 1/8-inch wide metal tines with clear spacing between the tines being not less than 1/4 inch nor more than 1/2 inch. If approved by the Engineer, other equipment and methods may be used, provided that a surface texture meeting the specified requirements is obtained. The texture shall be applied transversely. It is the intent that the average texture depth resulting from the number of tests directed by the Engineer be not less than 0.060 inch with a minimum texture: depth of 0.050 inch for any one test when tested in accordance with Test Method Tex-436-A. Should the texture depth fall below that intended, the finishing procedures shall be revised to produce the desired texture. 12. 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 proportions as approved by the Engineer in the mix design as submitted by a commercial laboratory 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. F13. Concrete Strength D-15 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 and/or a 28 day compressive strength of 3,600 pounds;per,square inch. The coarse aggregate factor A 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 (net gallons of water per sack of 94 pound cement) shall not exceed 6.0 gallon/sack. Concrete specimens:shall be prepared, cured and tested as outlined in TxDOT Bulletin C-11. 14. Workability of Concrete Concrete shall be uniformly plastic, cohesive,and workable. Workable concrete is defined as concrete which can be placed without honeycomb and without voids in the surface of the pavement. Workability shall be obtained r 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 — b. Addition of mineral filler to fine aggregate C. Increase of cement content -' In the event that the measures taken do not eliminate the bleeding immediately,.concrete placement operations will be suspended, as directed by 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 beams as specified in TxDOT 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 TxDOT Bulletin C-11. The slump shall not be less than l inch nor more than 3 inches. D-16 I 15. Mix Design Prior to the beginning of the concrete placement, and rthereafter 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. Mixes 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 tests necessary to determine its acceptability under these specification requirements. 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 k specimens. After the mix proportions and water -cement ratio required to produce concrete of the specified strength have been determined, placing of the concrete may be started. r' Type I cement shall have a specified 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. 16. 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 the D-17 r 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 conditions as directed by the Engineer. See Section D-2. 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 prepared surface. Sufficient subgrade shall always be prepared in advance to insure satisfactory prosecution of the work. No equipment 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. 17. 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 forms have been disturbed or any subgrade becomes unstable, the forms shall be reset and rechecked. In exceptional cases, the Engineer may require stakes driven to the grade of the bottom of the forms. Sufficient stability of the forms to support the equipment operated thereon and to withstand its vibration without springing or settlement 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 D-18 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 immediately rrepaired. 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 completed, the form trench, if used, shall be filled with earth from the shoulders in such a manner as to shed water from rainfall or curing away from the edge r of the pavement. On completion of the required curing, the subgrade 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. I. CONCRETE MIXING AND PLACING i. 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 begins. 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 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. f The initial batch of concrete mixed after each time the mixer is washed out shall be enriched by additional r`R F i D-19 mortar. The additional mortar shall be one sack of cement and three parts of sand. 2. Placing 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 400F, the temperature being taken in the shade and away from artificial 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 50OF`for not less than 5 days. When concrete is being placed in cold weather, other than under the conditions stated above, the Contractor shall have available a sufficient supply of an approved covering material to immediately protect concrete if the air temperature falls to 320F, or below, before concrete has been placed 4 hours. Such protection shall remain in place during the period the temperature continues below 320F 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 damage 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 sub -base, 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 sub -base 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. Workmen 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 spreading D-20 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 Engineer, 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. 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 cause 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 w 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 center line ,., of the pavement, and shall be rigidly secured in required position by such means (as shown on plans) that will prevent their displacement 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 �,. D•21 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. S. Weakened Plane Joints Weakened plane joints shall consist of transverse contraction joints and longitudinal joints and shall be 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 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 area 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 10 to 15-foot intervals shall be sawed as soon as sawing can be accomplished without damage to the pavement and before 12 hours after the concrete has been placed, the exact time to be approved by the Engineer. The remaining contraction joints shall D-22 be sawed in a uniform pattern as directed by the Engineer, and they shall be completed before uncontrolled r cracking of the pavement takes place. All joints shall be completed before permitting traffic to use the pavement. 7. Longitudinal Joints Longitudinal joints shall be sawed within two days after construction of the pavement. Sawing shall not cause damage to the pavement and the grooves shall be cut with a minimum of spalling. No traffic (including construction traffic) shall be permitted on the pavement until the longitudinal joint 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 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 gage. Such anchorage shall be sufficient to overcome the tendency of the material to fall out of the joint. 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. f After finishing is completed and the concrete still workable, the surface shall be tested for trueness with an approved 10-foot steel straightedge. The straightedge r- 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 leveled to this condition, in order to insure conformity pM '.�, D-23 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. Extra water will not be added for finishing. 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 pavement 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. 11. Protection of Pavement and Opening 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 D-24 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,OOO pounds. Such opening, however shall :in no manner relieve the Contractor from his responsibilities 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 as required for the safety of traffic. r 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 a' same provisions governing the opening after 14 days as above prescribed. Where 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. 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 after the last concrete 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. 2.EARTH WORK A. SUBGRADE PREPARATION FOR CURB AND GUTTER, STREETS, PAVING (ASPHALT AND CONCRETE) ALLEY RETURNS, ALLEY PAVING, VALLEY GUTTERS AND EARTH WORK. r D-25 L Description Sub -grade preparation shall include the removal, haul and disposal of all obstructions, including existing curbs, gutters, paving materials, 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 6" on residential streets and to a depth of 12" on major thoroughfares and collector streets. Compactors will be used from the bottom to the finished sub -grade elevation to compact the subgrade to 9511 Standard Proctor Density (ASTM D-698) in conformity to the line, grade and sections as shown on -the plans or as establishedbythe 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 section 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 done 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 (41) inches and compact each layer 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 otherwise specified by the Engineer, the scraper shall not exceed 23 cubic yards capacity as rated loaded flush by the manufacturer. 2. Compaction Subgrade shall be compacted to 95% Standard Proctor Density (ASTM D-698) for all improvements except thoroughfare and collector street paving. Subgrade shall be compacted to 100% Standard Proctor Density for thoroughfare and collector street paving. — Density tests (ASTM D-2922) will be performed and test rolling will be observed by City inspectors. Swelling subgrade (soils with plasticity index of 20 or more) shall be sprinkled as required to provide not less than optimum moisture during compaction. Other subgrade D-26 i soils will be compacted at a moisture content of plus or minus 2% of optimum moisture or other moisture content .• directed by the Engineer. Test rolling will be accomplished with a 25 ton pneumatic tire roller or other pneumatic tire, roller approved by the tw Engineer. The Engineer may require up to six passes of the roller in 'determining the condition of the subgrade. Any soft or unstable areas found by test rolling will be corrected by removing the soft or unstable material and replacing it with suitable material compacted to specified .,, 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 ••e profiles present a smooth riding surface and so that the compacted base thickness will not be less than six (611) or nine (911). Crown section shall begin to decrease 60-feet back of end of radius for residential streets. Wider street 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 base has started. 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 shall be wasted by the Contractor. �., Care shall be taken by the Contractor to use only topsoil in j 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 locate 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. 6. Subcrrade for Alley Paving The preparation of the subgrade for concrete alley paving shall be done in the same manner as other subgrade x excavation which requires scarifying, wetting, disking, D-27 t 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 to 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 (511).inches-at the centerline and seven and one-half inches (7-1/211) 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 (611) 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 Describtion "Prior to placing any embankment, all "Preparing,Right-Of- Way" and/or "Clearing and Grubbing" operations 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 embankment 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 roadbeds, the roadbeds slopes shall be plowed or scarified to a depth of not less than six (611) inchesand 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 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 permissible depth.of layer. D-28 roll 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 roadway, 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 layers 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 embankment 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 C 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 featheredged 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 dumping in a pile or ,.. windrow shall be incorporated in a layer in that position, but all such piles or windrows shall be moved by blading or similar methods. Clods or lumps of material shall be broken and the embankment material mixed by blading, disking, or similar methods to the end that a uniform material or D-29 uniform density is secured in each layer. Water 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 compaction 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 ASTM 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, and the compaction method may 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 areas 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 D-30 optimum for compaction to Standard Proctor Density. (Also see Section D, Item 2.A.2. Compaction.) E 2. 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 pipe 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 (611) 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 same manner and to the density prescribed 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 for placing roadway embankment as prescribed in the pertinent specification included in the contract. No construction traffic will be permitted to cross any pipe culvert until the minimum depth of fill above the pipe as determined by the Engineer has been placed and consolidated. 3. BASE COURSE The base course shall consist of a minimum of six (611) or nine (911) 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. D-31 A. HAULING AND PLACING Approved base material shall be hauled in vehicles of uniform capacity to the site and dumped evenly so that an adequate quantity of material will be placed to provide a minimum of six (611) inches of compacted base material on all -units except major thoroughfares streets. On these streets the Contractor will construct nine (911) inches of compacted base material. B. PROCESSING Processing of caliche base shall be accomplished in multiple lifts of three (311) 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 (311) inches and thoroughly moistened and rolled again. Succeeding layers shall then be placed similarly until the caliche base course is completed. Caliche base shall be compacted to 9511 Standard Proctor Density (ASTM D-698) for all improvements except thoroughfare street paving shall be compacted to 100i Standard Proctor Density. Density tests (ASTM D-2922) will be performed and test rolling for base will be observed by City inspectors. Caliche base shall be compacted at a moisture content of plus or minus 211 optimum moisture or other moisture content directed by the Engineer. The finished caliche base shall be test rolled with a 25 ton pneumatic tire or other approved roller. The Engineer may require up to six passes of the roller in determining the condition of the base. All nine (911) inch compacted caliche base shall be accomplished in three (311) inch lifts. The caliche course shall then be sprinkled as required and rolled with compactors as directed until a uniform compaction of specified "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 be smooth and in conformity with the typical sections shown on plans and to the established lines and grade. Traffic may be allowed to travel on the caliche base, as directed by the Engineer, during construction. During this period, the caliche base shall be satisfactorily maintained by the use of water trucks, blades, drags and such other equipment as may be required. The base course shall be so maintained until the wearing surface is placed thereon. The D-32 surface shall not be placed on base course that exceeds optimum mixture by two percent (2k). 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 "nests" of segregated coarse or fine material shall be corrected or removed and replaced with well graded material as directed by the Engineer. Each layer of black base may be test rolled, as directed by the Engineer, with a 25 ton pneumatic tire or other approved roller requiring up to six passes before succeeding layers are placed. A delay in construction of a black base mat or surface will require test rolling and approval. prior to construction of the next layer. C. FINISHING Description ti 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. 1. Failed Density or Weak Spots in Base The finished caliche base shall be checked for density requirements and by test rolling. Materials that fails the density requirement shall be reworked as necessary until passing. The full depth of caliche base shall be compacted to the extent necessary to remain firm and stable under test rolling. All irregularities, depressions or weak spots which develop shall be corrected immediately by scarifying the areas affected, adding suitable material as required, reshaping and recompacting by sprinkling and rolling. 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-eicthths (3/8) inch from the established grade or true cross section shall be corrected as provided above for defects. D-33 Longitudinally a straightedge 10 feet long shall be used to detect any deviation which shall be corrected as defects. 4.HOT MIX ASPHALTIC fONCRETE SURFACE Description This item shall consist of 1-1/2" compacted C.O.L.

A.Samplinct and Testing Hot Mix Asphaltic Concrete for Compaction Hot mix asphaltic concrete will be accepted on a lot basis. A lot will consist of 1000 tons or each days production and will be divided into three (3) equal_sublots. Pavement density will be determined by taking the average density for each lot, from the three sublots, the average Maximum Theoretical Density, taken from trucks delivering hot mix asphaltic concrete to the site. The samples will be tested in accordance with ASTM D-2041. Each lot of compacted pavement will be accepted, with respect to density, when the average field density is within the below listed specifications. Four field density determinations will be made for each lot. Cores taken from the pavement will be used to test the field density. The density of the cored samples will be determined in accordance with ASTM D-2726. Density Specifications Based on Maximum Theoretical Density Minimum _ 92.50 Optimum - 96.011 Maximum = 97.51-a If the mixture produced does not have the specified qualities, it shall be adjusted until it does. The pavement shall be constructed on the previously completed and approved subgrade, base, existing pavement, bituminous 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. B. Temperature Requirements 1.November 1 until April 1 D-34 r a. The asphaltic mixture shall not be placed when the air temperature is below 55 degrees F and falling. b. The asphaltic mixture may placed when the air temperature is above 50 degrees F and rising. 2. April 1 till November 1 a.

The asphaltic mixture may placed when the air temperature is above 45 degrees F and rising. 3.Asphalt Stabilized Base a. The asphaltic mixture shall not be placed, when the air temperature is below 45 degrees F and falling. b. The asphaltic mixture may be placed when the air temperature is above 40 degrees F and rising. The air temperature shall be taken in the shade away from artificial heat or as reported by the National Weather Service on their hourly report (Telephone No. 762-0141). 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. 4. Preparation of Base and Areas Borderincr 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. 5. Prime Coat The prime coat shall consist of an application of 0.25 gallons per square yard of MC asphalt. 6.

The surface shall be given a uniform application of tack coat r-,D-35 using asphaltic materials of this specification. This tack coat shall be applied, as directed by the Engineer, with 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. 7. Transportincr Asphaltic 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, limeslurryor 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. 8. Placinct 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. - 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 a coarse 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 D-36 when authorized by the Engineer, provided a satisfactory surface can be obtained by other approved methods. Adjacent to flush curbs, gutters, liners 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. All joints shall present the smoothness as other sections between old and new pavements work shall be carefully made between old and new sections The transverse e the Engineer, th with an approved surface for ,the contact surfaces be painted with material before 9 Compactinq same texture density, and of the course.

All of previously constructed pavement shall a thin uniform coat of hot bituminous the fresh mixture is placed. 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 on successive 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 provided for each job. Additional rollers shall be provided if 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 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 D-37 droppings of diesel, 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. 10.
