Construction method for paving of asphalt concrete pavement of road engineering
Construction speed and social benefits of mechanized paving Asphalt pavement construction speed, efficiency than the artificial paving greatly improved, in general construction conditions, the construction can better reflect the advantages. The construction temperature of the mixture in the paving is guaranteed, and the paving temperature, the initial temperature, the final pressure and the final pressure temperature, which must be controlled to ensure the quality, can be effectively controlled. 1.3 Construction of high qualityDouble Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery
The use of paver construction, the paver vibrator and automatic leveling system, the pavement of the overall quality can be guaranteed, especially in the pavement compaction, flatness and thickness of the three main quality indicators more than manual Paving is easy to control. To ensure uniformity of the mixture.Asphalt mixture in the mixing plant after mixing, after discharge, transport, discharge, resulting in material segregation, this uneven material by the spreader spreader in the distribution of materials when mixing The second mixing can be obtained to compensate for the defects of the material itself. Applicable scope: It is applied to asphalt roads, squares and runways of various widths greater than 3.0m. Especially for tight schedule, high quality requirements of large areas of asphalt mixture paving. Pre - construction preparation According to the design cross section, the arrangement width of the paver is rationally arranged. According to the quality requirements of the acceptance of grass-roots level, flatness, to avoid the end of the grass-roots level, poor surface roughness. According to the bottom, the acceptance of the grass-roots level and the design requirements of the asphalt surface calculation of the control points of the lofting data, select the appropriate cast coefficient (high coefficient must determine the paving thickness of the pavement thickness, material gradation, Vibrating stroke, paving speed).
