Spiral paver with left and right spiral, while the material to the left and right sides evenly paving, but also about independent drive. As the paver moves forward, the vibrating and ironing sections carry out preliminary vibrating and leveling of the ply according to a certain width, thickness and camber. The screed is equipped with heating means to heat the bottom of the plate during the cold season or before the start of the work, preventing the asphalt mixture from adhering. Since the screed has a floating characteristic, it is possible to adjust the thickness of the ply by changing the elevation angle of the screed plane with respect to the ground surface by the thickness adjuster. In the course of operation, the floating screed can also reduce the roadbed or pavement rough uneven pavement on the impact of flatness.
Some paver screed with the vibrator made of telescopic, spiral paver can be connected to or shortened to pave different width of the road. Screed regulation of manual or semi-automatic. Since the 1960s, the use of automatic leveling device, which is a pre-tensioned wire rope, smooth curb or pavement has been paved as a benchmark, the use of sensors at any time detection of subgrade or road surface roughness caused by screeding relative In the baseline position deviation occurred, and continue to adjust the traction arm around the traction point position to change the screed plane of the elevation angle, to achieve the purpose of high-precision leveling.
Generally meet the requirements of the highway. The factors affecting the pavement quality are asphalt mixture properties, feed quantity and paving speed, so in recent years there has been able to automatically control the pavement layer formation, feeding speed and paving speed of the whole Hydraulic, fully automatic asphalt concrete paver.
The basic technical parameters of the asphalt concrete pavers are hopper capacity, paving width, maximum paving thickness and working speed.
