Asphalt concrete construction method from quangongzi's blog

The adhesive layer is laid before the asphalt concrete pavement. 1.5 hours before the start of the sprinkling of the asphalt layer, the surface of the lower and lower layers is slightly wetted with water and the traffic is restricted. Sprinkle the sticky oil evenly with the sprinkler equipment approved by the supervising engineer, and the spreading temperature and sprinkler rate shall comply with the technical specifications. Note that precautions should be taken to prevent contamination of other appendages (such as guardrails, etc.) during spraying. For excessive sprinkling of the place must be modified asphalt from the sprinkled surface scraping, leakage or less sprinkle the place must be made up. The viscose-modified asphalt should be finished within 24 hours prior to paving the cover. The surface temperature of the cloth must be higher than 10 ℃, moderate wind speed.Road Repair Equipment - Doan Machinery

Asphalt concrete surface construction

After the milling, the modified 4% AC-13C type modified asphalt concrete and the middle layer are sprinkled with modified emulsified asphalt adhesive layer. The old and new asphalt concrete transverse joints are imported with double-sided adhesive bonding. The surface layer cracks at the location of the use of anti-cracking paste for processing. Using the factory concentration of mixed asphalt mixture, dump truck insulation transport, paver paving, roller rolling molding of the construction process. Asphalt concrete used in the pile of storage, and in the construction of a sufficient number of qualified materials before storage, stacking materials with 15cm thick cement concrete hardening, in the material and material boundary with brick walls, to prevent mixed materials. The room is equipped with intermittent asphalt mixing station 1, the output is 100t / h. Mixing station equipped with temperature detection system flow, and with finished storage silo and secondary dust removal equipment. In addition, there are two sets of powder with automatic lecturer device to join the system. At the same time there are two (100t /) asphalt storage tank, and heated with heat transfer oil.
