6 Page 11 of 17 in inaccurate or generally poor quality work or results in the waste of material shall be replaced immediately as directed by the Owner s Representative. A. Asphaltic Concrete Pavers: Bituminous concrete pavers shall be self-contained, power-propelled units, provided with an activated screed or strike-off assembly, heated if necessary, and capable of spreading and finishing courses of asphaltic concrete 8 feet to 12 feet wide and from 3/4 inch to 6 inches in depth, true to the line, grade and crown, with or without the use of forms or side supports. The screed or screeds shall be adjustable to lay courses in widths of more than 8 feet in 6-inch increments or less. The paver shall have sufficient power and traction to operate efficiently on grades up to 8 per cent. The receiving hopper shall be of such size and capacity as to prevent any delay in emptying the trucks during spreading operations. The hopper shall be equipped with distribution screws or paddles to place the mixture in front of the screed or screeds evenly. Pavers shall be equipped with mechanical devices such as equalizing runners, straightedge runners, evener arms or other compensating devices to adjust the grade line so that any unevenness in the foundation or other course upon which the paver travels will not be reflected in the surface of the course being laid, and with devices to confine the edges of the mixture to true lines. The screed or strike-off assembly shall operate by cutting, crowding or other practical action which is effective on mixtures at the workable temperature specified, without tearing, shoving or gouging, and shall produce a finished surface without segregation and of the evenness and texture specified. The screed or screeds shall be adjustable as to level and shall have an indicating level attached thereto in full view of the operator. The pavers shall be so designed that they will provide a connection of the bituminous concrete between adjacent strips of pavement, which will be smooth and well bonded. When laying mixtures, the pavers shall be capable of being operated at forward speeds varying from 10 to 50 feet per minute consistent with satisfactory work, and shall be equipped with a quick and efficient steering device. B. Spreaders for Leveling Course(s): Spreading equipment used for leveling course(s) shall either be of the type described above or a motor grader equipped with smooth tires or a combination of both. C. Vehicles for Transporting Bituminous Mixtures: The mixture shall be transported from the mixing plant to the Project in motor trucks equipped with tight, clean bodies which shall be lightly lubricated with a thin oil, lime solution or dusted with hydrated lime, to prevent the mixture from sticking to the bodies. Each truckload of mixture delivered shall be covered with a canvas tarpaulin or other approved material of such size, and so fastened, as to protect the mixture from the weather. D. Rollers: Rollers shall be in good condition, capable of reversing without backlash and capable of compacting the mix to the required density. Rollers shall conform to the requirements of Section 400 of the Standard Specifications MATERIALS: A. Asphalt cement shall conform to Section 820 of the Standard Specifications and shall be PG

7 Page 12 of MIXES: B. The coarse aggregate shall be Group II crushed stone, gravel, or slag, free of salt, vegetable matter and other extraneous matter, and conforming to the requirements of Section 400 and , Standard Specifications. C. Fine aggregate shall be Group II conforming to the requirements of Section , Standard Specifications, except that local materials (natural sand) shall not be used. D. Hydrated lime shall meet the requirements of Section Standard Specifications. A. New Pavement: The job-mix formula shall comply with Sections and 828 of the Standard Specifications for the following applications. Job-mix formulas shall be established in accordance with Section of the Standard Specifications. B. Leveling: The job-mix formula shall comply with Sections and 828 of the Standard Specifications for Type H asphaltic concrete, except as modified herein where the thickness of layer is between 0 and 1.5 and Type E where the thickness of layer is greater than PLACEMENT: The method of construction shall conform to DOT Section 400 of the Standard Specifications except as herein modified. A. Leveling: A leveling course shall be constructed over existing pavement that contains pockets of depressions, gouging, settlement adjacent to existing structures, etc. The leveling course shall be completely leveled to the feathered edges after compaction. In limited areas where the use of mechanical spreading and finishing equipment is impractical due to obstacles, hand spreading may be used if authorized by the Owner s Representative. B. Limitations to Spreading: For all pavement applications, the mixture shall be spread only on a prepared surface in compliance with these specifications. The surface shall be properly cured, firm and dry, unless otherwise directed. No mixture shall be placed that cannot be compacted and finished at the end of the workday. The mixture as it is placed shall be between 250 degrees F and 350 degrees F, and uniform throughout the mixture. The temperature of the mixture shall be measured by infrared thermometer as it comes out from the screed and recorded by the Contractor for submission to the Owner s Representative. No mixture shall be placed when the atmospheric temperature is below 40 F. No mixture shall be placed in the rain or when surface is wet. Only one layer may be placed during a workday.

8 Page 13 of 17 C. Placing Mixture: 1. Alignment: All asphaltic concrete mixtures, not laid between curbs or curb and gutter sections, shall be laid using string lines. 2. Hand Spreading: In limited areas where the use of mechanical spreading and finishing equipment is impractical due to obstacles, hand spreading may be used if authorized by the Owner s Representative. C. Compacting Mixture: 1. After the spreading and strike-off and while still hot, the course shall be compacted thoroughly and uniformly by rolling. The contractor shall establish a rolling procedure prior to start of paving that will ensure all provisions of the contract specifications are met. The procedure shall be based on layer thickness, type mix, type of aggregate asphalt content, temperature, weather conditions, mixing temperature or any other criteria necessary to provide a high quality properly compacted pavement. 2. Each roller shall be operated by a competent experienced roller operator and must be kept as nearly as practicable in continuous operation while the work is under way. Rolling shall begin at the sides and progress gradually to the center, until the entire surface has been rolled by the rear wheels. Rolling shall be continued until all roller marks are eliminated and the finished surface meets the requirements specified. The speed of steel wheeled rollers shall not exceed 3 miles per hour and at all times shall be slow enough to avoid displacement of the hot mixture. Any displacement occurring as a result of the reversing of the direction of the roller, or from any other cause, shall be corrected at once by the use of rakes and of fresh mixture when required. To prevent adhesion of the mixture to the roller, the wheels shall be kept properly moistened with water by means of saturated mats or by other means approved by the Engineer but excess water will not be permitted. Care shall be exercised in rolling not to disturb the line and grade of the edges of the asphaltic concrete. Pneumatic tired rollers shall be used in conjunction with breakdown rollers on all courses. 3. The surface of the pavement after compaction shall be smooth and true to the established grade within the tolerances hereinafter specified. Any pavement that is segregated or becomes loose and broken or mixed with dirt, or is in any way defective shall be removed and replaced with fresh hot mixture, which will be immediately compacted to conform to the surrounding area. Any area showing an excess of bituminous material or segregation shall be removed and replaced. 4. Pavement mixture shall be compacted to 95 percent of the density determined by ASTM D1559 when 75 blows per-face compactive effort is used in forming the laboratory sample 5. Leveling Course: The mixture shall be compacted to 96 percent of the density determined by ASTM D1559 when 50 blows per-face compactive effort is used in forming the laboratory sample. D. Surface Requirements: Before final acceptance, the finished surface of the bituminous concrete shall be tested at right angles to the centerline of the pavement with a 10-foot straightedge. Variations of the finished pavement

9 Page 14 of 17 surface from the required surface shall not be more than 1/8 inch when tested both parallel and normal to the longitudinal centerline. The templates and straightedges shall have projections of the bottom at each end, either built-in or firmly attached, so that they will be supported 6 inches above the pavement surface at the ends. They shall be free from warp and deflection, shall be subject to approval by the Owner s Representative, and shall be furnished by the Contractor without additional compensation. The tests for surface smoothness specified above shall be made by the Contractor immediately after initial compression. Variations shall be corrected by removing or adding materials, as may be necessary. Then rolling shall be continued as specified. Immediately after rolling and while the pavement is still hot, the smoothness of the course shall be checked again and all projections or depressions exceeding the specified tolerances shall be corrected by removing defective work and replacing it with new surface course as specified. Portions of the surface which are unsatisfactory shall be replaced to the satisfaction of the Owner s Representative. All testing of the pavement surface shall be performed by the Contractor in the presence, and in a manner subject to the approval, of the Owner s Representative and without additional compensation. E. Opening to Traffic: For all pavement applications, traffic will not be permitted on newly finished surfaces prior to 24 hours after their completion except by permission or direction of the Owner s Representative.
