The third to control the paving of asphalt mixture. When the truck arrives at the paver, the paver will adjust the initial state. The thickness and width of the paving are subject to design. Paving process, the paver to test shop to determine the paving speed and vibration, vibrating frequency uniform forward, is strictly prohibited midway speed or pause. Paved asphalt mixture in the unconfirmed before the construction workers shall not stampede. In the rain or construction temperature below 10 ��, can not pave the asphalt mixture. The fourth to control the asphalt mixture rolling. Mix to complete the paving should be immediately after the inspection of the road, the irregularities in a timely manner with manual adjustment, followed by full and uniform compaction. Asphalt mixture compaction to test section to determine the combination of rolling and procedures, compaction of the initial pressure, pressure and final pressure of three stages. The initial pressure: the use of two-wheel light wheel roller (�� 8 tons) in the mixture after the paving regulator, at least 2 times rolling, rolling speed of 2 km / h ~ 3 km / h, after the first check flatness And road arch, if necessary, to be trimmed. Pressure: the pressure immediately after the start of the pressure, the pressure with a vibratory roller and tire roller to complete, usually with the vibration machine rolling 3 times ~ 4 times, and then tire rolling machine 4 times to 6 times, so that It reaches the required degree of compaction. oral irrigation sewing machine emergency trailer replace seller road speed breaker price crack sealer at walking speed
