Final approval will be given only after full-scale production has begun. 2.1 MIXING PLANT: Mixing plants shall meet the requirements of the applicable local State Highway Department specifications for Hot Mix Plants. 2.2 Bituminous-Materials Spreaders: Bituminous-materials spreaders shall be the self-propelled type equipped with hoppers, tamping, or vibrating devices, distributing screws, adjustable screeds operated either manually or automatically, equipment for hea ting the screeds and equalizing devices. The spreader shall be capable of spreading hot bituminous mixtures without leaving indented areas, tearing, shoving, or gouging and capable of producing a finished surface conforming to the smoothness requirements specified hereinafter and placing the course to the required thickness. If an automatic grade control device is used on the spreader for two-lane paving operations, it shall consist of sensing device for control of one end of the screed and a slope-control mechanism for control of the other end of the screed, or a sensing device on each side of the paving machine. Where the paver is used on multiple paving lanes (more than two paving lanes), sensing devices shall be used on each side of the spreader for co ntrol of the screed. The slope-control mechanism shall not be used for grade control in multiple paving lane operations. 2.3 Steel-Wheel Rollers: Steel-wheel rollers shall be self-propelled, three-wheel, (two-axle) and tandem (two-axle) types, weighing not less than 20,000 pounds each. The three-wheel rollers shall have a minimum weight of 300 pounds per inch of width of rear wheel. Wheels shall be equipped with adjustable scrapers, water tanks, and sprinkling apparatus for keeping the wheels wet; thereby preventing the bituminous mixture from sticking to the wheels. Rollers shall be capable of reversing without backlash and free from worn parts. Roller wheels with flat and pitted areas or projections that leave marks in th e pavement will not be permitted. Three-axle tandems will be permitted in lieu of two-axle tandems if approved by the Contracting Officer. 2.4 Heavy Pneumatic-Tired Rollers: Heavy pneumatic-tired rollers shall be self-propelled and shall consist of two axles on which are mounted multiple pneumatic-tire wheels in such manner that the rear group of wheels will not follow in the tracks of the f orward group but spaced to give essentially uniform coverage with each pass. Axles shall be mounted in a rigid frame provided with a loading platform or body suitable for ballast loading. Tires shall be smooth and capable of being inflated to at least 90 p.s.i. Construction of the roller shall be such that each wheel can be loaded to a minimum of 4,500 pounds. 2.5 Blowers and Brooms: Blowers and brooms shall be power type and suitable for cleaning the surface to be paved. 3.0 EXECUTION: 3.1 WEATHER LIMITATIONS: Bituminous courses shall be constructed only when the base course or intermediate course is dry and when the weather is not rainy. 3.2 PREPARATION OF SURFACE: Bituminous mixtures shall not be placed with-out ample time to complete spreading and rolling during daylight hours, unless approved satisfactory artificial lighting is provided. Immediately prior to placing the bituminous b ase or surface course, all loose material, dirt, clay, or other objectionable material shall be removed from the surface. An asphalt tack coat shall be applied to all existing asphalt concrete surfaces in advance of the asphalt concrete overlay placement. The asphalt tack shall be placed at an asphalt residue coverage rate of 0.05 gal/sq yd. 3.3 TRANSPORTATION OF BITUMINOUS MIXTURE: The bituminous mixture shall be transported from the mixing plant to the site in trucks having tight, clean, smooth beds coated with a minimum amount of a concentrated solution of hydrated lime and water to preve nt adhesion of the mixture to the truck beds. Each load of mixture shall be covered with canvas, or other suitable material of ample size to protect the mixture from the weather and to prevent loss of heat. Deliveries shall be scheduled so that spreading and rolling of all mixture prepared for one day's run can be completed during daylight. The mixture shall be delivered in such manner that the temperature at the time of dumping into the spreader will be not less than hereinafter specified. Loads that h ave crusts of cold, unworkable material or have become wet by rain will be rejected. Hauling over freshly placed material will not be permitted. 3.4 Installation: 3.4.1 PLACING: Any layer of surface source shall not be left uncovered by the subsequent course for more than 5 days, weather permitting. Material trucks hauling materials other than asphaltic concrete or tack coat shall not travel on previously constru cted layers of asphaltic concrete until the final surface course is constructed. 3.4.2 Joints: 3.4.2.1 General: Longitudinal joints of the overlay shall be offset at least 1 foot from existing joints. Transverse joints shall be offset at least 2 feet from existing transverse joints. Joints between old and new pavements or between successive day' s work, or joints that have become cold because of delay, shall be tacked and shall be made carefully to insure continuous bond between old and new sections of the course. All joints shall have the same texture, density, and smoothness as other sections o f the course. The tack shall be overlapped onto the previous pavement 1 or 2 inches. Contact surfaces of previously constructed pavements, curbs, gutters, manholes, etc., shall be tacked. If these surfaces have become coated with dust, sand, or other ob jectionable material shall be cleaned by brushing or cut back with an approved power saw, as directed. The surface against which new material is to be placed shall be sprayed with a thin, uniform tack coat. The material shall be applied far enough in adv ance of placement of the fresh mixture to insure adequate curing. Care shall be taken to prevent damage or contamination of the sprayed surface. 3.4.2.2 Transverse Joints: The roller shall pass over the unprotected end of freshly placed mixture only when placing of the course is discontinued or when delivery of mixture is interrupted to the extent that unrolled material may become cold. In all c ases, the edge of the previously placed course shall be cut back to expose an even, vertical surface the full thickness of the course. In continuing placement of strip, the mechanical spreader shall be positioned on the transverse joint so that sufficient hot mixture will be spread to obtain a joint after rolling which conforms to the required density and smoothness specified herein. When required, the fresh mixture shall be raked against the joints, thoroughly tamped with hot tampers, smoothed with hot i rons and rolled. 3.4.2.3 Longitudinal Joints: Longitudinal joints in surface course or intermediate course shall be offset as stated above. Procedures outlined in specification paragraph: Special Requirements for Placing Strips Succeeding Initial Strips shall be follow ed when making longitudinal joints. Edges of previously placed strips that have cooled or are irregular, honeycombed, poorly compacted, damaged, or otherwise defective, and unsatisfactory sections of the joint shall be cut back to expose a clean, sound su rface for the full thickness of the course as directed. When required, fresh mixtures shall be raked against the joint, thoroughly tamped with hot tampers, smoothed with hot irons and rolled. 3.5 General Requirements for Use of Mechanical Spreader: The range of temperatures of the mixture, when dumped into the mechanical spreader shall be as determined by the Contractor. Asphalt mixtures having temperatures less than 235 degrees F. when dum ped into a mechanical spreader will be rejected. The mechanical spreader shall be so adjusted and its speed so regulated that the surface of the course being placed will be smooth and continuous without tears and pulling, and of such depth that, when comp acted, the surface will conform with the cross section, grade, and contour shown on the drawings. Unless otherwise directed, placing shall begin along the centerline of areas paved on a crowned section or on the high side of areas with a one-way slope, an d shall be in the direction of the major traffic flow. The mixture shall be placed in consecutive adjacent strips having a minimum width of 10 feet, except when edge lanes require strips less than 10 feet to complete an area. Each strip placed before a s ucceeding strip shall be of such length that sufficient heat will be retained to make the strip readily compactable so that a joint can be obtained conforming to the requirements for texture, density, and smoothness specified in the paragraph: JOINTS. Th e length of any strip to be laid prior to the succeeding strip shall be as directed and may be decreased or increased as dictated by changes in climatic conditions. Longitudinal joints and edges shall be constructed to true line markings. The Contractor shall establish lines parallel to the centerline of the area to be paved and shall place string lines coinciding with established lines for the spreading machine to follow. Number and location of lines shall be as directed. Placing of the mixture shall b e as nearly continuous as possible, and the speed of placing shall be adjusted, as directed, to permit proper rolling. 3.6 Special Procedures to Prevent Segregation: The wings of the spreader hopper shall not be emptied (flipped) between truckloads. The screed auger shall be operated approximately three-fourths (3/4) full and the hopper conveyor shall not be allowed to run out of material. 3.7 Special Requirements for Placing Strips Succeeding Initial Strips: In placing each succeeding strip after the initial strip has been spread and compacted as specified hereafter, the scre ed endgate of the mechanical spreader shall overlap the previously placed strip slightly and shall be 1.25 times thicker than the existing compacted strip in order to produce a smooth compacted joint with the specified density. Mixture placed on the edge of the previously placed strip by the mechanical spreader shall be pushed back (tucked) to the edge of the strip being placed by use of a lute (rake). The pushed back material shall form a ridge on the uncompacted strip along the edge of the previously pl aced strip. The height of the ridge above the uncompacted strip should be approximately equal to the thickness being allowed for roll down during compaction. Procedures similar to these outlined above shall be used to facilitate getting a smooth joint wi th density. When the quantity of mixture on the previously placed strip plus uncompacted material in the strip being placed exceeds that required to produce a smooth, dense joint, the excess mixture shall be removed and wasted. Excess material shall not be spread over the uncompacted mat. 3.8 Shoveling, Raking, and Tamping After Machine Spreading: A sufficient number of experienced shovelers and rakers shall follow the spreading machine, adding hot mixture and raking the mixtures as required to produce a course that, when completed, will conform to all requirements specified herein. Broadcasting or fanning of mixture over areas being compacted will not be permitted. When segregation occurs in the mixture during placing, the spreading operation shall be suspended until the cause is determ ined and corrected. Irregularities in alignment of the course left by the mechanical spreader shall be corrected by trimming directly behind the machine. Immediately after trimming, the edges of the course shall be thoroughly compacted by tamping lateral ly with a lute. Distortion of the course during tamping will not be permitted. 3.9 Hand Spreading in Lieu of Machine Spreading: In areas where the use of machine spreading is impractical, the mixture shall be spread uniformly with hot shovels and hot rakes in a loose layer of a thickness that, when compacted, will conform to the re quired grade and thickness. During hand spreading, each shovelful of mixture shall be carefully placed by turning the shovel over in a manner that will prevent segregation. In no case shall the mixture be placed by throwing or broadcasting from a shovel. The loads shall not be dumped faster than can be properly handled by the shovelers and rakers. 3.10 COMPACTION OF MIXTURE: Compaction of the mixture shall be accomplished by the steel-wheel rollers and pneumatic-tired rollers specified above. Rolling shall begin as soon after placing as mixture will bear roller without undue displacement. Delays in rolling freshly spread mixture will not be permitted. After initial rolling, preliminary tests of crown, grade, and smoothness shall be made by the Contractor under supervision of the Contracting Officer. Before rolling is continued, deficiencies sha ll be corrected so that finished course will conform to requirements for grade and smoothness specified herein. Further smoothness checks shall be made by the Contractor as directed by the Contracting Officer. After preliminary smoothness tests, rolling shall be continued until density is obtained in all portions of each course of not less than 95 percent of density of laboratory compacted Marshall specimens taken behind the paver. 3.11 Density Tests: Density of the compacted mixture of the surface course shall be determined by tests made on specimens tested in accordance with the requirements of ASTM D 2726. 3.12 Operation of Rollers, Tampers and Vibro Plate Compactors: The speed of rollers shall be slow enough at all times to avoid displacement of the hot mixture. Displacement of the mixture resulting from reversing the direction of the roller or from any o ther cause shall be corrected at once by use of rakes, and fresh mixture shall be appli ed or removed when necessary. Alternate passes of the roller shall be varied slightly in length. During rolling, the wheels of steel-wheel rollers and plates of vibro plate compactors shall be moistened to prevent adhesion of the mixture to the wheels or plates, but excess water will not be permitted. Tires of heavy pneumatic roller shall be moistened with soapy water when required to prevent mixture from sticking to tires during rolling. Rollers shall not be permitted to stand on finished courses until the courses have thoroughly cooled. The minimum number of rollers shall be adequate to obtain the specified density. Places inaccessible to rollers shall be thoroughly compacted with hot hand-tampers or vibro plate compactors. Unless otherwise directed by Contracting Officer, a pneumatic-tired roller shall be used as an intermediate roller. Longitudinal joints shall be pinched to ensure compaction with the pneumatic-tired roller. The roller shall make at least one complete pass (forward and backward) operated on the hot lane as the intermediate roller. The roller shall be operated with its outside tire as close as possible to the previously placed lane. 3.13 Correcting Deficient Areas: Mixtures that become contaminated or are defective shall be removed. Skin patching of an area that has been rolled will not be permitted. Holes the full thickness of the course shall be cut so that the sides are perpend icular and parallel to the direction of traffic and the edges are vertical. Edges shall be sprayed with tack coat. Sufficient fresh paving mixture shall be placed in the holes so that finished surface will conform to the grade and smoothness requirements . The paving mixture shall be compacted to the density specified herein. 3.14 EDGES OF PAVEMENT: Edges of pavement adjacent to the shoulders shall be trimmed neatly to line. Shoulder material not less than 1 foot wide shall be placed against and to the full height of the pavement surface as soon as practicable after final r olling has been completed and the pavement has sufficiently hardened. 3.15 PROTECTION OF PAVEMENT: After final rolling of the pavement, no vehicular traffic of any kind shall be permitted until the pavement has cooled and hardened or for at least 6 hours. 3.16 SURFACE SMOOTHNESS: After final rolling, the pavement surface shall not vary in excess of 1/8 inch from a 10-foot straightedge laid on the surface parallel with the centerline. When a 10-foot straightedge is laid on the surface transverse to the ce nterline between the crown and the edge of the pavement, the surface shall not vary more than 1/4 inch from the straightedge. 4. MEASUREMENT: Bituminous mixture shall be weighed on standard truck scales. Scales shall be approved by an inspector of the State Inspection Bureau charged with scale inspection within the State in which the project is located. In lieu of weighing on scales, the Contractor may submit copies of waybills or delivery tickets during the progress of the work. The weighing shall be done after mixing on public or other scales which have been approved by the Contracting Officer and certified by the State whe re the scales are located. . 5 COMPUTATION OF QUANTITIES: Asphaltic concrete surface courses shall be computed in tons of mixture delivered to the project and placed. The computations will be based on the waybills and delivery tickets submitted. The accumulative totals will be roun ded off to the nearest 0.1 tons. 6. TRAFFIC CONTROL: The Contractor shall furnish, maintain, relocate, and remove any necessary traffic control signs and barricades so as to control traffic during all construction operations in accordance with the latest edition of the Manual of Uniform Traffic Control Devices for Streets and Highways (M.U.T.C.D.). Signs shall be installed to safely control traffic. Location of signs will be the Contractor's responsibility.
