Construction Technology and Method of Permeable Oil Layer and Under Seal
The top of the grass roots should be sprayed through the oil layer and the lower sealing layer, oil through the use of emulsified asphalt. Spreading the SBS modified asphalt on the oil, spraying the amount of asphalt is not less than 1.6 / ㎡; 5-10mm diameter gravel gravel, gravel coverage of 60-70%, the amount of about 6m3 / 1000 ㎡; 9-13t rubber roller roller, the whole number of rolling over the number of not less than 2 times; the next layer using synchronous asphalt gravel, construction equipment requires the use of synchronous gravel layer car. Followed by the construction of the next layer. Asphalt concrete pavement between the asphalt layer must be sprayed with viscous oil, viscous oil using fast crack emulsified asphalt dosage of 0.3-0.6L / m, sticky layer of oil to be used asphalt sprinkler spraying, and should be spread in the day, To be emulsified asphalt demulsification, evaporation immediately after the completion of paving asphalt layer, to ensure that the viscous layer of oil from pollution.Small Road Roller - Shanghai Doan Machinery Technology Co.,Ltd
Construction Technology and Method of Asphalt Surface
Use double paver full width paving, before and after the adjacent 10-20m, paving width should be 5-10cm overlap, paver equipped with balance beam, the end, the use of alignment method, the surface with a balance beam.
Paver according to the speed of paving material to determine the speed, to avoid half-way stop and other materials occur.
Paver stalls must be stopped after a complete stop forcibly linked to files and in the ramp shift or neutral sliding.
Check the mixture temperature before discharge, should not be less than 120 ℃.
Open shop before the paver screed temperature of not less than 65 ℃.
Double-steel wheel 2 times, rubber tire 3 times, are vibration, the temperature is not lower than 80 ℃; the final pressure (double-pressure), the pressure is not less than 100 ℃; , Double-wheel static pressure 2 times, the temperature is not less than 65 ℃.
Compaction method: followed by, slow, high frequency, low amplitude, uniform speed, not to stay, steering and braking, rolling from low to high, adjacent rolling width overlap 30cm, folding position to ladder with paving Machine forward.
Seam rolling: Rolling by stitching, roller into the new stall 15cm, each compaction and then extended into the 15cm, all the rollers to the new shop section, the longitudinal roller.
Seam size: transverse staggered staggered 1m, should not be left longitudinal seam, must stay, stagger 15cm or more.
