The initial pass with the roller should be made as soon as it is possible to roll the bituminous mixture without cracking the mat or having the mix adhere to the roller wheels . E) The rolling shall be done by a " Rolling Train " , consisting of a steel wheel seal roller, and a pneumatic tired traffic roller and a steel wheel finish roller. All of which shall be on the job when the asphalt laying commences and remain on the project until the paving work has been completed . F) Rolling of the longitudinal joint should be immediately behind the paving operation . The initial pass with the roller should be made as soon as it is possible to roll the bituminous mixture without cracking the mat or having the mix adhere to the roller wheels . To prevent adhesion of the mix to the roller, the wheels should be kept moist with only enough water to avoid picking up the material . G) Steel wheeled rollers shall be of the tandem type . For seal rolling, these rollers shall weigh between 5 and 12 tons and for final rolling , they shall weigh between 8 and 12 tons . H) Traffic rollers shall be of the self propelled pneumatic tired type , equipped with at least seven (7) smooth tread , low pressure tires , with the tire pressure maintained between 50 to 55 pounds . Traffic rollers shall weigh between 6 and 10 tons . Wobble wheeled rollers are prohibited from I rolling on this project . 1 ) The speed should not exceed 3 mph for steel wheeled rollers or 5 mph for pneumatic tired rollers . J ) Finish rolling should be done while the material is still workable enough for removal of roller marks , before the pavement temperature has dropped below 140 ° F . Abrupt turning of rollers on the paving mix which causes undue displacement shall not be permitted . Finish rolling should be accomplished by use of the steel wheel roller. K) Should any irregularities or defects remain in any course after compaction , they should be removed promptly and replaced with new material to provide a uniform texture surface conforming to line and grade . The finished surface shall be such that it will not vary more than one forth inch ( 1 /4") from the ten foot ( 10') straight edge applied both parallel and perpendicular to the center line of the pavement . The thickness of the pavement shall be no more than one forth inch ( 1 /4") greater or less than the specified thickness . Correction of deficiencies in pavement thickness will be in strict accordance with those procedures described in Section 330 14 . 2 of the Florida D . O . T . Specifications for Road and Bridge Construction , 1986 Edition . L) Areas which are inaccessible to a roller (such as adjacent to curbs , gutters ,, manholes , etc) shall be compacted by the use of hand tamps , small vibratory tampers , or other satisfactory means . M ) The edges of the wearing surface shall be straight , true , and clean in all cases , and must meet the approval of the Engineer. Should the edges of the wearing surface not meet the approval of i the Engineer, they shall be saw cut to a straight, true , clean line by the Contractor at his expense . i I I i i i i RP-4 -2 l i
