The surface course shall be transported in tight sealing vehicles previously cleaned of all foreign material . The inside surface of the truck bodies shall be thinly coated with soapy water or an acceptable asphalt release agent prior to receiving asphalt concrete. . Diesel, kerosene, gasoline or any other hazardous or environmentally detrimental material shall not be used to lubricate the truck bed. Cover each load during cool and cloudy weather when there is a possibility of rain. 3 . 05 PATCHING AND LEVELING COURSES Where asphalt concrete is to be installed on an existing paved surface or old base which is irregular, or where indicated on the Plans, the existing surface shall be brought to proper grade and cross section by the application of patching or leveling courses. 3 . 06 PLACING ASPHALT CONCRETE The placement of asphalt concrete for patching, leveling and subsequent courses shall conform to the Florida D. O.T. Standard Specifications for Road and Bridge Construction, 2006 Edition, Section 330-9 . 3 . 07 COMPACTING ASPHALT CONCRETE The Contractor shall provide a separate set of rollers, with their operators, for each paving or leveling train crew working at the job. All coverage requirements for rolling shall be conducted before the surface temperature of the asphalt concrete drops to the extent that effective compaction can not be achieved or the rollers begin to damage the pavement course. Compaction and joints for as freshly laid asphalt concrete courses shall be installed in compliance with the Florida D. O.T. Standard Specifications for Road and Bridge Construction, 2006 Edition, Section 330- 10 and 330- 11 . 3 . 08 FIELD QUALITY CONTROL A. The longitudinal installation of all asphalt concrete courses shall be required to be checked by a rolling straightedge . The straightedge shall have a minimum effective length of 15 feet. The finished surface of base or structural surface courses shall not vary more than 3/8 inch from the straightedge applied parallel to the centerline of the pavement. The finished surface of final surface courses shall not vary more than 3/ 16 inch from the straightedge applied parallel to the centerline of the pavement. Any pavement section exceeding the above tolerances may be rejected by the Engineer. B . The transverse cross slope shall be checked at up to 10 locations for each days work. When the difference between the measured cross slope and the design cross slope varies by more than t 0.2% for travel lanes or f 0. 5% for shoulders, the paving operation shall be stopped and corrected. Should the average measurement for the 10 locations be above the specified tolerance, the measured pavement section may be rejected by the Engineer. 3 . 07 CORRECTING UNACCEPTABLE ASPHALT CONCRETE The Contractor shall be required to correct rejected pavement sections by; removing and replacing; overlaying; or other method in compliance with the Florida D.O.T. Standard Specifications for Road and Bridge Construction, 2006 Edition, Section 330- 12 .4. END OF SECTION 02741 a3 02741 - Asphaltic Concrete Surface Course
