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 applicable to the work of subcontractors and to give the Contractor the same power as regard 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 of 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 installation. .� 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. TWO -COURSE MAINTENANCE AND OVERLAY ON 70TH STREET The Contractor's attention is directed to the fact that a two -course surface treatment, followed by a hot -mix overlay, is to be constructed on 70th Street from Slide Road to Albany Ave. This work must be accomplished during periods of lowest traffic volume. The Contractor shall anticipate this portion of the project being accomplished between 9:00 A.M. and 4:00 P.M. with all work being closely coordinated between the adjacent property owners, the Owner's Representative, and the Contractor. This coordination must be accomplished at least 72 hours before any work begins in this area. The Contractor shall receive no extra compensation for extra effort required at each property owner's driveway. The extent of overlay on each property owner's driveway shall be as directed by the Engineer. 14. PARTIAL PAYMENTS On or before the tenth day of each month, the Contractor shall submit to Owner's Representative an application for partial payment. Owner's Representative shall review said application for partial payment and the progress of the work made by the Contractor and if found to be in order shall prepare a certificate for partial payment showing as completely as practical the total value of the work done by the Contractor up to and including the last day of the preceding month. 15. 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 and defects due thereto and pay for any damage to other work resulting therefrom, which shall appear within a period of one (1) year from date of final acceptance of the project. The Owner or the Owner's Representative shall give notice of observed defects with reasonable promptness-. 16. 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) time the regular governing per diem wage rates. Any laborer, workman or mechanic required or permitted to work in excess of 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.

GENERAL The following paragraphs give the specifications on the various materials which are to be used in this project. On minor items a certificate from the manufacturer may be required, certifying that the material or equipment meets the specifications for such material as specified herein. All materials shall be subject to the approval of the Engineer before being used. 2. CONCRETE A. Cement Cement shall conform to "Standard Specifications and Test for Portland Cement, "A.S.T.M." Serial Designation C150, Type I and Type III, and shall be an approved brand. B. Aggregate Description r„ Concrete aggregates shall consist of natural, washed and screened sand, and washed and screened gravel or clean crushed stone conforming to "Standard Specification for Concrete Aggregate, "A.S.T.M. Serial Description C-33-39 and item No. 360 of the Texas State Highway Specifications. Coarse aggregate for Class "C" Concrete Street Paving shall be crushed limestone (Brownwood Type). The aggregate shall be well graded from coarse to fine and shall be free from injurious amount of clay, soft or flaky materials, loam or organic impurities. All aggregate shall be approved by the Engineer before use. Maximum size of aggregate shall be 1-1/2 inches. 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 A.S.T.M. Designation C-88- 76. 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 -- by drift fences of any suitable material approved by the Engineer, when sandstorm possibilities exist. Care will be IV-1 taken to prevent dusty conditions in the stockpile area from any sources. 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 design mix 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 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 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. IV-2 A strength test shall consist of five standard test cylinders made from a composite sample obtained in accordance with the requirements of ASTM Designation 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 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. The results of the 3 or 7 day strength tests will be compared with the 3 or 7 day strength of the preconstruction 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. Continuous mixing during transit will be insisted �- upon. Mix Design All concrete for curb and gutter, valley gutters, fillets and alley stubs, alley slabs, drainage channels, inlet boxes, headwalls, and medians shall be Class A concrete IV-3 with 5% air entrainment (±1-1/2% tolerance). The concrete mix design shall be based on water -cement ratio, and shall be as follows for the different classes of concrete. Minimum Sacks Max. Gal. Max. Slump Class Cement per C.Y. Water per sack in inches A 5 6.5 4 C 6 6 3 E 5.5 5.5 3 F 6 5.5 2 The concrete mix design for the different classes shall also be such that the compressive and flexural strength for each class shall not be less than the following: Class 3 day 7 day A --- 2100 C --- 3000 E 2500 3000 F 2900 3500 Minimum Average for any test beam strength 600 28 day 3000 3600 Any concrete failing to meet these strength requirements or air content shall be removed and replaced. Low Strength Concrete Any class of concrete incorporated in any part of the project which does not meet the strength requirements specified above, shall be considered low strength concrete. Low strength concrete shall be removed and replaced at the expense of the Contractor. The Engineer shall determine the exact limits of any low - strength concrete required to be removed and replaced under the provisions of this paragraph. The methods to be used in removing and replacing such concrete shall be approved by the Engineer. F. Classification Unless otherwise shown on the plans: Class A concrete shall be used for curb and gutter, drainage channels, medians, inlet boxes, headwalls and sidewalks; Class C concrete shall be used for concrete paving and valley gutters constructed in thoroughfare and collector streets; Class E concrete shall be used for valley gutters on IV-4 streets other than thoroughfares and collectors and for alley returns, alley paving and reinforced gutter sections; Class F concrete is used for railroad sections. G. Mixing All aggregates shall be accurately weighed or measured by volume. The concrete shall be mixed in an approved batch mixer equipped with an accurate water measuring tank, and shall be mixed for one and one-half minutes after all material is in the mixer. "Ready Mixed" or "Transit Mixed" concrete may be used. If used it shall conform to these specifications and the "Standard Specifications for Ready Mixed Concrete," A.S.T.M. Serial Designation C94-38 and Item No. 502 of the Texas State Highway Specifications. After mixing, the concrete shall be transported to the forms in a manner which will prevent separation or segregation of the aggregates and shall be placed without undue delay. It shall be deposited as nearly as practicable in its final position in order to avoid rehandling or flowing of the concrete. No water shall be added to the concrete to facilitate finishing. H. Curing Compounds Compounds used to form an air tight membrane over fresh concrete surface for curing purposes shall conform to Item 526, Texas State Highway Specifications and "A.S.T.M." Serial Designation C-309. 3. STEEL REINFORCING A. Wire Mesh Wire mesh reinforcing shall conform to "Standard Specifications for Welded Steel Fabric for Concrete Reinforcement" ASTM Designation A-185. Mesh reinforcement shall be of the size shown on the plans. All reinforcement shall be permanently marked with grade identification marks or shall, on delivery, be accompanied by a manufacturer's guarantee of grade and compliance with these specifications. Reinforcement stored on the site shall be protected from accumulations of grease, mud or other foreign matter and from rust producing conditions and shall be free from rust, scale, oil, mud or structural defects when incorporated into alley slab, or valley gutters. IV-5 B. Bar Reinforcing Reinforcing steel to be used on this project shall conform to A.S.T.M. Designation A-432 and shall be deformed to A.S.T.M. 305 requirements unless otherwise shown on the plans. 4. JOINT MATERIAL A. Expansion Joint Materials Bituminous premolded expansion joint material shall conform to Item No. 420.2 (a) of the Texas State Highway Department Specifications. Expansion joints shall be placed as shown on the plans or as directed by the Engineer. B. Joint Sealing Material Joint sealing material shall be W.R. Meadows sof-seal.or approved equivalent 5. FORMS Forms for curb and gutter and alley paving may be of wood or metal, of a section satisfactory to the Engineer, straight, free of warp, and a depth equal to the depth of the concrete section formed. Forms shall be constructed accurately to the line and grade as established in the field, shall be adequately braced so that they will not move during the placing of the concrete, and shall remain in place at least twelve (12) hours after placing concrete. Forms shall be oiled with a light oil before each use and forms which are to be re -used shall be cleaned immediately after each use and maintained in good condition. Curb forms shall be such that the face of the curb can be formed by use of a face form held in place by steel templates. Forms used for curb shall meet all of the above specifications, except that face forms on curb radii may be omitted if a true section and an accurate flow can be obtained by other methods approved by the Engineer. In no case will a concrete pour be started without the approval of the Engineer. No forms shall be placed until the subgrade is within inch (111) of its finished grade. Forms for alley slabs may be used as a guide for screeding. Where longitudinal construction joints are required, the form shall be so constructed as to provide a 1-1/8 inch "V" shaped groove in the face. IV-6 p-- 6. FLEXIBLE BASE (CALICHE) A. Description "Flexible Base (Caliche)" shall consist of a foundation course for surface course or for other base courses. It shall be composed of caliche and stone materials and shall be constructed as herein specified in one or more courses in conformity with the typical sections shown on plans and '~ to the lines and grades as established by the Engineer.

The roller shall not be allowed to stand on any portion of the pavement mixture 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 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 roadway, either when the rollers are in -, operation or when standing. IV-25 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 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 acceptable to the Engineer. Unacceptable finished surfaces may be corrected by the placement of additional mixture, all at the expense of the Contractor. K.

Aggregate General The mineral aggregate shall be composed of coarse aggregate, a fine aggregate, and if required, a mineral filler. Samples of coarse aggregate, fine aggregate and mineral filler shall be submitted to the City of Lubbock Testing Laboratory for testing and approval by the Engineer. Approval of other material and of the source of supply must be obtained from the Engineer prior to delivery. The combined mineral aggregate, after final processing by the mixing plant, and prior to addition of asphalt and mineral filler, shall have a sand equivalent value of not less than 34, unless otherwise shown on the plans when tested in accordance with Test Method Tex.-203-F. The percent of flat or elongated slivers of stone for any course shall not exceed 25%. A flat or elongated sliver is hereby defined as one whose minimum thickness is less than one-half its length. Prior to stockpiling of aggregates the area shall be cleaned of trash, weeds and grass and be relatively smooth. Aggregates shall be separated into stockpiles of different gradation, such as a large coarse aggregate and a small coarse aggregate stockpile and such that the grading requirements of the specified type will be met when the piles are combined in the asphaltic mixture. No coarse aggregate stockpile shall contain more than 10 percent by weight of materials that will pass a No. 10 sieve except as noted on the plans or provided for by special provision. Fine aggregate stockpiles may contain small coarse aggregate in the amount of up to 15 percent by weight, 100 percent of which shall pass a 1/4 inch sieve, however, the coarse aggregate shall meet the quality tests specified herein for "Coarse Aggregates." Suitable equipment of acceptable size shall be furnished by the Contractor to work the stockpiles and prevent segregation of the aggregates. If the Contractor utilizes an asphalt continuous mix plant, the various aggregate stockpiles of different gradation will be stockpiled in the same manner as described for stockpiling of aggregate for asphalt stabilized base. That is the stockpiling of the aggregate shall be made up of layers of material not to IV-27 exceed two feet in height of each layer. The edge of each succeeding layer shall extend inward so as not to overlap the edge of the layer below. In loading from the stockpile, the material shall be loaded by making successive vertical cuts through the entire depth of the stockpile. (1) Coarse Aggregate The coarse aggregate shall be that part of the aggregate retained on a No. 10 sieve; shall consist of clean, tough, durable fragments of crushed stone of uniform quality throughout; mixing or combining crushed gravel and crushed stone will not be permitted. The aggregate shall be crushed to the extent that produces a minimum of 90% crushed faces when tested in accordance with Test Method (Tex.-413-A). The aggregate shall have a maximum of 15% loss when subjected to 4 cycles of the Magnesium Sulfate Soundness Test (A.S.T.M. C-88-73). When coarse aggregate is tested in accordance with Test Method Tex.-217-F, the amount of organic matter, clays, loams or particles coated therewith or other undesirable materials shown on the plans shall not exceed 2 percent. When it is specified that the coarse aggregate be sampled during delivery to the plant, from the stockpile, or from the cold bin, the material removed when tested in accordance with test method Tex.-217-F (Part II, Decantation), shall not exceed 2 percent. The plasticity index of that part of the fine aggregate contained in the coarse aggregate passing the No. 40 sieve shall not be more than 6 when tested by the Test Method Tex.-106-E. However, where the coarse aggregate contains less than 5 of fine aggregate and the fine aggregate is of the same or similar material as the coarse aggregate., the P.I. requirements for the material passing the No. 40 sieve may be waived by the Engineer in writing. When it is specified that the coarse aggregate be sampled from the hot bins and tested in accordance with Test Method Tex.-217-F (Part II Decantation), the amount of material removed shall not exceed 1 percent. Tests performed as specified herein represent material processed or placed until a subsequent test is performed. The coarse aggregate shall have an abrasion of not more than 40 percent loss by weight when subjected to the Los IV-28 Angeles Abrasion Test, Test Method Tex-410A. Coarse aggregate from each source shall meet the abrasion requirements specified. ( 2 ) Fine Aggregate The fine aggregate shall be that part of the aggregate passing the No. 10 sieve and shall consist of sand or screenings or a combination of sand and screenings. The plasticity index of that part of the sand passing the No.40 sieve shall not be more than 6 when tested by Test Method Tex-106-E. The plasticity index of that part of the screenings passing the No. 40 sieve shall be not more than 9, unless otherwise shown on plans, when tested by Test Method Tex-106-E. Fine aggregate from each source shall meet plasticity requirements. Sand shall be composed of durable stone particles free from injurious foreign matter. Screenings shall be of the same or similar material as specified for coarse aggregate. (3) Mineral Filler The mineral filler shall consist of thoroughly dry stone dust, slate, dust, portland cement or other mineral dust approved by the Engineer. The mineral filler shall be free from foreign and other injurious matter. When tested by Test Method Tex-200-F (Dry Sieve Analysis), it shall meet the following grading requirements: Passing a No. 30 sieve Per Cent By Weight 100 -- Passing a No. 80 sieve, not less than 90 I- Passing a No. 200 sieve, not less than 65 (B) ASPHALTIC MATERIAL (1) Asphalt for Paving Mixtures Asphalt for the paving mixtures shall be of the types of oil asphalt as determined by the Engineer. IV-29 The grade of asphalt used shall be as designated by the Engineer after design tests have been made using the mineral aggregates that are to be used in the project. If more than one type of asphaltic concrete mixture is specified for the project, only one grade of asphalt will be required for all types of mixtures, unless otherwise shown on plans. The -- Contractor shall notify the Engineer of the source of his asphaltic material prior to production of the asphaltic mixture and this source shall not be changed during the course of the project except on written permission of the Engineer. (2) Tack Coat The asphaltic material for tack coat shall meet the requirements for Cut -Back Asphalt RC-2, or shall be a Cut -Back Asphalt made by combining 50 to 70 percent by volume of the asphaltic material as specified for the type of paving mixture with 30 to 50 percent by volume of gasoline and/or kerosene. If RC-2 Cut -Back Asphalt is used, it may, upon instructions from the Engineer, be diluted by addition of an approved grade of gasoline and/or kerosene, not to exceed 15 percent by volume. (C) PAVING MIXTURES Types The paving mixture shall consist of a uniform mixture of coarse aggregate, fine aggregate and asphaltic material. The grading of each constituent of the mineral aggregate shall be such as to produce, when properly proportioned, a mixture which, when tested in accordance with Test Method Tex-200-F (Dry Sieve Analysis), will conform to the limitations for master grading given below for the type specified. IV-30 (1) Type "C" (Coarse Graded Surface Course) Passing 7/8" sieve ............................ 100 Passing 5/8" sieve.......................98 to 100 _Passing 5/8" sieve, retained on 3/8" sieve....................................12 to 25 Passing 3/8" sieve, retained on No. 4 sieve....................................15 to 30 Passing No. 4 sieve, retained on No. 10 sieve .................................... 12 to 30 Total retained on No.10 sieve.....................................53 to 65 Passing No. 10 sieve, retained on No. 40 sieve.................................... 10 to 20 Passing No. 40 sieve, retained on No. 80 sieve ..................................... 5 to 15 Passing No. 80 sieve, retained on No. 200 sieve......................................5 to 15 Passing No. 200 sieve ..................... .1 to 6 (2) Modified Type "C" (Coarse Graded Surface Course) The Engineer may designate the use of a modified Type "C" Surface Course. This design will stay in the limits of the above Type "C" but may vary from the upper limits of certain sieve designations to the lower limits of other sieve designations. (D) LABORATORY CONTROL If the Contractor or supplier wish to use a material or location not previously approved by the City of Lubbock, he will be required to request approval in writing of the material not less than 60 days prior to anticipated use of the material. The City of Lubbock laboratory test results shall be the sole consideration for approval of materials, mix designs, adequacy of procedures, etc.. The results of such testing shall be evaluated and final approval given by the City Engineer. The City of Lubbock will utilize its own testing laboratory to monitor the plant mixing for Black Base and IV-31 0- 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 specification are exceeded for aggregate, black base, or hot mix, appropriate corrections will be required. (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 tolerances allowed herein and shall remain within the limitation 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.......................................+ or -2 Asphalt Material ..........................+ or -0.2 IV-32 0- (F) 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 aggregate and the asphalt content - designated by the Engineer by more than the respective tolerance specified above. (See Section IV-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 Concrete mixture has been corrected and subsequent grading and extraction tests indicate results within the tolerance stated herein. All Hot Mix Asphaltic Concrete mixture 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. Marshall No. of compaction blows, each end of specimen 75 50 Stability, Lbs. 1200 --- 1000 --- Flow, units of 0.01 in 8 16 8 18 % Air Voids Surfacing or Leveling 3 5 3 5 Stability and density tests are control tests. 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 IV-33 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. 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 Street and Highways, Part VI, issued in May, 1983. 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 open to traffic all necessary Regulatory, Warning and Guide signs shall be in place. Signs required by temporary conditions or restrictions shall be removed immediately 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 is standardization with respect to design and placement, and uniformity of application is equally IV-34 r-- 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 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. 13. SEAL COAT AND TWO -COURSE MAINTENANCE A.

Curb and Gutter (Class A -Concrete) Description 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 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's approval as to driveway widths and location, in addition to the section, and line and grade approval before any pour is p- started on any curb and gutter unit. (2) Excavation and Subgrading (See Section V-2) 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 r-- inch) or more shall be brought to the correct elevation by scarifying, wetting, disking, blading, rolling and compacting 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 immediately be relocated behind the ^- proposed curb and gutter by the Contractor. V-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. 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. V-2 (5) Finishing r` 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. Curb and gutter shall be finished uniformly by wood trowelling 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. V-3 (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 shown on the plans. 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. Extra water will not be added for finishing. Unless otherwise specified by the Engineer, joints shall be constructed as follows: Expansion joints shall be located at each end 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) Curing 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 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 V-4 0 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 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 with structural damage and defective flow line found at time of surfacing shall be handled as described in sentence 2 above. B.

Reinforced Alley Paving Slab and Alley Returns (Class E Concrete) Description This item shall consist of reinforced concrete paving of variable thickness (5" to 7-1/211) constructed in the center 10 feet of alleys and shall be constructed of Class E concrete. All alley paving and alley returns shall be constructed in accordance to the Alley Paving Details. (1) Forming Forms for alley slab shall be placed where necessary to form the outside edge of slab (where slab is not bordered by concrete curb and gutter or other permanent improvements such as building, docks, etc.)and where necessary to form construction and expansion joints (See "Alley Paving Details" on plans). On all edges, joints, etc. to be formed, the forms shall extend the entire depth of concrete. (2) Subgrade Preparation (See Section V-2) W= (3) Reinforcing Care shall be taken to securely hold the welded wire mesh 3" above the bottom of the slab by use of high chairs or pre -cast concrete blocks. Concrete shall not be poured during sandstorms. Concrete shall be protected to maintain temperature of not less than 50 degrees F. for five (5) days after placement. If aggregate and water are heated, they shall not be heated above 90 degrees F. Concrete shall not 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 could effect 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. (4) Finishing Concrete shall be deposited so as to conform roughly to the finished cross-section. Sufficient concrete shall be placed to allow for shrinkage and extra material for finishing. Extra water will not be added for finishing. The shape and flow line of the alley paving slab may be established by the use of two (211) inch by four (411) inch wood screeds, or other approved removable devices, accurately staked to line and grade. If such devices are used they shall be in place before the final finishing of the subgrade and the subgrade shall be finished so that the concrete slab will be of the proper depth. The concrete shall be "struck off" to the true section and finished smooth by floating and troweling. The final finish shall be provided by brushing to provide a nonskid surface for traffic. Particular care shall be taken in the final troweling and finishing so that the -� finished slab presents a smooth straight surface without waves in the edge and without pockets in the flow line. "~ (5) Curing and Protection All concrete work shall be covered with burlap or other suitable material as soon as it has set sufficiently to prevent marking and kept wet V-7 continuously for at least (4) days. Care shall be taken to prevent mechanical injury to concrete work during this period and until the work is accepted. Any work damaged prior to acceptance shall be repaired by the Contractor at his own expense and to the satisfaction of the City Engineer. The City Sanitation Department shall be notified of all alley return and alley paving construction, and if possible, the length of time said return and/or alley shall be closed to traffic. The Contractor shall properly flare and barricade alley returns and alleys during the period of construction and as long afterward as the Engineer may require for curing and achieving strength. Before opening alley returns to traffic, the contractor shall properly fill and level by hand, (no maintainer shall be used until full strength of concrete is achieved), the adjacent approaches from the street and alley. In all cases, no alley or alley return shall be opened to traffic without the approval of the City Engineer.

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) Replacement of Damaged Concrete or Concrete Surface Only patching of very minor nature will be allowed in alley paving. Any substantial damage occurring to the alley paving prior to the acceptance of the unit in which the damage occurs will be remedied by removal and replacement of the entire section or sections of V-8 alley paving that has been damaged. Any slab removed to a joint other than a doweled expansion joint will be replaced using joint section B-B in the Special Detail Sheets of these specifications. Extreme care shall be taken by the Contractor during "Setting -Up" _ period to prevent vandals, sand or rain from marring the surface finish to avoid being 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. When fabricated steel bar or rod mats are specified, the mats shall meet the requirements '^ of ASTM Designation: 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. V-15 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 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. V-16 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 be held to a minimum. 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 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 V-17 metal tines with clear spacing between the tines being not less than 1/4 inch nor more than l/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. (13) 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 and/or a 28 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 (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 THD Bulletin C-11. V-18 (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 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 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. .� (15) Mix Design Prior to the beginning of the 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. V-19 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 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. 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 plans and the lines and grades established by the Engineer. V-20 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 V-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 V-21 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 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 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 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 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 (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 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. V-22 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. 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 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 40F, 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 500 F 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 320 F, or below, before concrete has been placed 4 hours. Such protection shall remain in place during the period the temperature continues below 320 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 V-23 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 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 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 V-24 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 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 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. V-25 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 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 be sawed in a uniform pattern as directed by the Engineer, and they shall be V-26 completed before uncontrolled 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 or approved equivalent. 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 Finishin 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 completed 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 V-27 P-- 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 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. V-28 (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 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 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. 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 V-29 ordered by the Engineer, subject to the 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. 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 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. V-30 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 r- 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 (411) 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 The subgrade will be wetted and rolled 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 "^ (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 P- on the detail sheet. V-31 (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 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 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) Subgrade for Alley Paving 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 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. V-32 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" 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) 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 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. 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 r., 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 to the general plans and each to the detailed Engineer. After and completed embankments shall correspond shape of the typical sections shown on the section of the embankment shall correspond section or slopes established by the completion of the roadway, it shall be V-33 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 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 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. V-34 (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 950 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, 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 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 V, Item 2 [A] Compaction.) V-35 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 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 (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. 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 ,Po 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 and 95% Proctor Density has been attained. 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 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 be smooth and in conformity with the typical sections shown on plans and to the established lines and grade. 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 r- 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 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. The utilization of the traffic to compact and bind the base is an essential part of the construction, and whenever V-37 possible 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%) 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, depression 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 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 (3L) inch from the established grade or true cross section shall be corrected as provided above for defects. Longitudinally a straightedge 10 feet long shall be used to detect any deviation which shall be corrected as defects. ►�3 4. HOT MIX ASPHALTIC CONCRETE SURFACE A. Description This item shall consist of 1-1/2" compacted T.H.D. Type "C" 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. r„ (1) General ---(Test Method Tex-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 (1-1/211). 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, 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. Temperature Requirements A. November 1 until April 1 1. The asphaltic mixture shall not be placed when the air temperature is below 550 degrees F and falling. 2. The asphaltic mixture may be placed when the air temperature is above 500 degrees F and rising. B. April 1 till November 1 1. The asphaltic mixture shall not be placed when the air .., temperature is below 500 degrees F and falling. 2. The asphaltic mixture may be placed when the air temperature is above 450 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). V-39 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 Bordering 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. (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 application of tack coat 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. (5) Transporting 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, lime slurry or other material satisfactory to the Engineer, if necessary, to prevent mixture from V-40 adhering to the body. hauls, canvas covers be required. Vehicles prohibited. (6) Placing In cool weather or for long and insulating of truck bodies may of the semi -trailer type are 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 (1-1/21). 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 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 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. 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 V-41 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. (7) 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 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 droppings 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 V-42 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 centerline 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. When placed on existing surfaces, the 1/8 inch deviation in 10 feet 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 vehicle in a satisfactory manner when the mixture is dumped into the finishing machine. The finishing machine shall be equipped with a flexible spring and/or hydraulic type hitch sufficient in design and capacity to maintain contact between the rear wheels of the hauling 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 shall be V-43 mechanically and/or automatically operated in such a manner that overloading the finishing machine being used cannot occur and the required lines 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 a 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. Pneumatic Tire Rollers. The pneumatic tire roller shall be an acceptable self-propelled roller mounted on pneumatic tired wheels, with the weight capable of being varied uniformly from 275 to 550 pounds per inch width of tire tread, so constructed as to be capable of being operated in both a forward and a reverse direction and shall have suitable provision for moistening the surface of the tires while operating. All tires of the same roller shall be smooth tread of equal size 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 5 pounds per square inch. V-44 Two Axle Tandem Roller. This roller shall be an acceptable power 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 the roller may be kept level during rolling. The drive 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. When 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. All 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, 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 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,corrugates or shoves, it will be the contractor's responsibility to correct this condition at his expense. 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 V-45 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. Adjustment 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 finishing the base and before application of asphalt. It shall be the responsibility of the Contractor to notify the Water and Sewer 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 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 utility company.

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 project 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 on all 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 V-47 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. Private contracts do not have plans, but utility companies will 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. When utility adjustments commence before the contract is awarded, it will be the responsibility of the utility company to barricade the project. Unless otherwise agreed upon by the City and the utility companies involved, the sequence of installation of underground utilities shall be as follows: Utility Sewer Electric (Primary) Electric (Secondary) Telephone T.V. Cable Water Gas Sequence First Second Third Fourth (last if no power or T.V.) Fifth Sixth Seventh Traffic Engineering Eighth On all projects, including private contracts, the Contractor shall not place curb and gutter or base material at points where underground utilities cross or propose to - cross until such utilities have been adjusted or installed. V-48 0- 7. SALVAGING AND REPLACING BASE A. Description "Salvaging and Replacing Base" shall consist of removing the existing base material where shown on plans, such temporary storage as is necessary, and the replacement of this material on the prepared roadbed as herein specified and in conformity with the typical sections shown on plans and to the lines and grades as established by the engineer. B. Construction Methods (1) Salvaging Existing Base .-, The existing base, including any bituminous mat not shown on plans to be salvaged, shall first be cleaned of all dirt or other objectionable material by blading, brooming or other approved methods, then scarified to the width and depth as may be required to provide the estimated amount of salvaged material per station as shown on the plans. Subgrade shall be reworked, if necessary, as directed by the Engineer. Any bituminous mat encountered shall be broken into particles not more than two inches in size, and incorporated uniformly with the existing base. The material thus salvaged shall be placed in stockpiles or windrows until sufficient subgrade has been prepared to receive the salvaged material; then, if the Contractor so elects, the remaining old base material as salvaged may be placed directly upon the prepared subgrade as directed by the Engineer, thus eliminating the necessity of stockpiling. It shall be the responsibility of the Contractor that all the available material shall be salvaged and replaced and shall be kept reasonably free of soil from the subgrade or roadbed during the salvaging and replacing operations. When material is windrowed or stockpiled, it shall be so placed not to interfere with traffic, proper drainage or the general progress of the work. (2) Preparation of Subgrade Preparation of subgrade shall be in accordance with Section V, Item 2 Earth Work of these specifications. (3) Replacement of Salvage Material The salvage material shall be in accordance with Section V, Item 2 Earth Work of these specifications. V-49 8. Salvaging and Stockpiling Base Material A. Description This item shall consist of salvaging base material from places shown on the plans or as directed by the Engineer and of stockpiling that material where shown on the plans or directed by the Engineer. B. Construction Methods Trash, wood, brush, stumps and other objectionable material at the storage site shall be removed and disposed of as directed by the Engineer prior to the beginning of work required by this item. The base material, including any asphalt mat, which may not be shown on the plans, shall be cleaned of all dirt or other objectionable material. Asphaltic materials shall be broken into pieces not more than two inches in size and incorporated uniformly with the salvaged base material. Material to be salvaged shall be worked into stockpiles or windows and loaded by approved equipment into approved equipment for hauling to the stockpile site. It shall be the responsibility of the Contractor that all the available material shall be salvaged and kept reasonably free of soil from subgrade or road bed during the salvaging operations. The operation shall be conducted in'such manner as not to interfere with traffic, drainage or the general requirements of the work. After the material is deposited in the stockpile area, it shall be worked into a neat compact stockpile. 9. SEALING AND TWO -COURSE SURFACE TREATMENT A. 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 sealing and two -course operation is started. Asphalt shall not be applied when general weather conditions, in the opinion of the Engineer, are not suitable. B. HANDLING 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 a manner that there will be no contamination of the asphalt with foreign material. V-50 Asphalt is not to be heated above 4000 F at any time, and when applied, 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 4000 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 Contractor 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 of the 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 application 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. Asphalt shall not be applied if the ambient temperature is below 65 F. 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. 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. 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. V-51 C. RATE OF APPLICATION OF MATERIALS S.H.D. Gals Spread Grade No. of Asphalt/S.Y. Ratio 1. Seal Coat (Pre -coated crushed stone or pre -coated gravel) #4 0.28 2. Two -Course P.B. Pre -coated crushed stone or Pre -coated gravel (a) Thoroughfares 1:100 #2 Special 0.28 1:62 #4 0.38 1:90 (b) Collectors #2 Special 0.28 1:62 #4 0.38 1:90 D. 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 controlled 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 requires 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. After the first and second application of aggregate, on the two -course it will be thoroughly rolled with pneumatic V-52 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 cleansed 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 specified above. r., Care shall be taken in loading aggregate from the stockpiles to prevent getting dirt and other foreign matter into aggregates. Loads of aggregate containing dirt will be rejected. E. HANDLING ASPHALT AND AGGREGATE FOR NIGHT WORK Application of asphalt and aggregate at night shall be applied by the same methods as for daylight application except that all equipment that is to be used on the street after shall have sufficient lights in compliance with State vehicle code. Additional lights 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.) F. 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 surface 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 V-53 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. G. PATCHING AHEAD OF SEAL OR TWO -COURSE MAINTENANCE The black base and cement stabilized caliche material to be used in patching ahead of the seal coat or two -course maintenance shall be used at locations as directed by the Engineer. No substitutions shall be permitted without prior approval from the Engineer. The areas to be patched shall be only as marked and measured by the Owner's Representative. The area to be patched shall be barricaded at all times during patching operations. However, if the Owner's Representative permits the patched area to be opened to traffic prior to placing the final hot -mix surface, the Contractor shall taper the edges of the patch with mix to minimize any bumps or inconvenience to traffic. (1) PATCHING WITH BLACK BASE Patching shall include removing the existing surfacing, six (6) inches of the caliche base, and if the 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 before the next lift is placed. The surface course, 1-1/2" of type "C" hot -mix, shall then be placed and rolled until the required density is obtained. 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. (2) 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 patching 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-54 (3) PATCHING WITH 1-1/2" OF TYPE "C" HOT -MIX Same as above (patching with black base) except only the existing asphalt surface will be removed. Both black base and cement stabilized caliche are anticipated being used, with locations of each type of material to be directed by the Engineer. H. CLEANUP 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. I.

A .. separate asphalt cement feed pump and finished product pump are required. This until shall have both an asphalt cement totalizing meter in gallons and a flow rate meter in gallons per minute. J. ASPHALT -RUBBER MIXING AND REACTION The percentage of granulated rubber shall be 22 percent plus or minus 3 percent by weight of total asphalt -rubber mixture, the exact granulated rubber content shall be as determined by the mix design submitted by the asphalt - rubber supplier. During placement the granulated rubber percentage shall not fluctuate by more than 1 percent by weight of total asphalt -rubber mixture. The temperature of the asphalt cement shall be between 350 and 425° F at the addition of the granulated rubber. The asphalt and rubber shall be combined and mixed together in the asphalt -rubber blending unit and reacted in the V-55 r-. distributor for a period of time as required by the Engineer which shall be based on laboratory testing by the asphalt -rubber supplier. The temperature of the asphalt - rubber mixture shall be above 3250 F during the reaction period. After the reaction between asphalt cement and granulated rubber has occurred, the viscosity of the hot asphalt - rubber mixture may be adjusted for spraying and/or better "wetting" of the cover material by addition of a diluent. The diluent shall comply with the requirements of Item 13.F of "Materials of Construction" and shall not exceed 7.5 percent by volume of the hot asphalt -rubber mixture. When a job delay occurs after full reaction, the asphalt - rubber may be allowed to cool. The asphalt -rubber shall be reheated slowly just prior to application but not to a temperature exceeding 350° F. An additional quantity of diluent not exceeding 3 percent by volume of the hot asphalt -rubber mixture may be added after reheating. K. APPLICATION OF ASPHALT -RUBBER MATERIAL The asphalt -rubber mixture shall be applied at a temperature of 3200- 340°F at the rate specified by the Engineer.
