Asphalt Surface Construction Of Geotextile

1. The construction method of asphalt surface layer is consistent with that of ordinary asphalt pavement surface layer. The pavement structure and thickness design should adopt the methods specified in the "Design Specification for Highway Asphalt Pavement" (JTJ014) or "Technical Specification for Highway Maintenance" (JTJ073). The thickness of the asphalt overlay is generally 4-6 cm for old asphalt concrete pavement.
When paving asphalt mixture, the paving temperature must be strictly controlled!
If the temperature is too high, the concrete is easy to burn out; The temperature is too low, which affects the compaction degree.
2. The compaction degree of the road surface is very important for the quality of the road surface. Insufficient compaction of the road surface can lead to cracking, looseness, rutting, and other phenomena, seriously affecting the service life of the road surface..
