Paving, hot mix asphalt paving machinery should be used, Shenzhen asphalt engineering / construction team asphalt / bitumen construction team / asphalt pavement construction in Shenzhen expressway and highway should use two or more joint pavers paving, to reduce the longitudinal seam times cold press, vertical distance of two adjacent pavers 10 ~ 30m, the lateral width of the paving should be 5 ~ cm overlap. Shenzhen asphalt contractor / construction team Shenzhen asphalt / bitumen Shenzhen Engineering / Construction asphalt paving asphalt paver process by dump truck unloading the mix in the hopper, the transmitter will mix later spread to the spiral spreader, with the paver forward, Shenzhen asphalt engineering / construction team asphalt / bitumen construction team / Shenzhen spiral paving asphalt pavement construction is that paving mixture evenly on the paving width, then tamping spread flat by leveling. Construction or connected with the old asphalt pavement demi longitudinal seam, when not using hot joints, should additional baffle or by cutting knife together. Must be laid before the other demi edge seam cleaned, Shenzhen asphalt engineering / construction team asphalt / bitumen construction team / Shenzhen asphalt pavement construction and brush sticky asphalt. Paving should have been laid in overlapping layers 5 ~ 10cm, after paving the paving work with the above mix demi front shovel away. Grassroots preparation and stakeout, before paving asphalt, bitumen Shenzhen Engineering / construction team asphalt / bitumen construction team / Shenzhen asphalt pavement construction should check to make sure the quality of the underlying, while lower quality does not meet the requirements, or not provided for spraying through layer, sticky layer of hot asphalt or lay down when sealing layer, not paved asphalt surface. In order to control the thickness of the paving mixes, ready after the grassroots level, should be measured stakeout, that the road surface at the centerline of the road width and the fourth set like pile, marked mix loose laying thickness.
