What should be paid attention to when laying asphalt pavement?
During construction, the protection of finished construction materials is a very important task. The main protective measures for asphalt concrete include:
(1) After the asphalt concrete is poured, remove the concrete on the formwork in time, and take covering protection measures in strict accordance with the construction plan.
(2) It is forbidden to hit the concrete surface with heavy hammer, and it is not allowed to make holes and grooves at will.
(3) Before the final setting of concrete, it cannot withstand excessive pressure, so it is forbidden to work by people, and it is strictly carried out in accordance with the construction plan to ensure sufficient intermittent time and maintenance period.
After the final pressure, when the road surface temperature drops below 50°C, the guardrails and tools on the road surface are removed, and traffic can be opened only after the supervision engineer agrees. Strengthen maintenance management to ensure that the road surface is clean and tidy, and ensure the normal drainage performance of the road surface. When cracks are found, scientific treatment measures are taken in time to prevent the disease from continuing to develop. Strengthen traffic management and restrict the passage of large overloaded vehicles. During the continuous high temperature in summer, arrange for heavy vehicles to pass in the early morning and at night when the road surface temperature is low.
