Construction method of water retaining and cooling asphalt pavement
The invention provides a construction method of a water retaining and cooling asphalt pavement. The method includes the steps of: S1. matrix asphalt mixture construction; S2. water retaining mortar perfusion; S3. mortar clearing; and S4. pavement curing. The invention adopts a unique rolling forming method, ensures the strength of asphalt mixture and the pavement roughness, at the same time makes the matrix asphalt mixture form a skeleton pore structure and have large porosity, thus guaranteeing enough filling space of the asphalt mixture. At the same time, the invention employs a labor and machine assisted method for perfusion of cement-based water retaining mortar to fully fill the gaps of the matrix asphalt mixture, thereby effectively ensuring the integrity and strength of the pavement, solving the construction and perfusion difficulty of engineering water retaining mortar, simultaneously guaranteeing the water retaining and cooling effects of the pavement, and ensuring the quality of the water retaining and cooling asphalt pavement. In addition, the method provided by the invention standardizes the construction technology of water retaining and cooling asphalt pavement, improves pavement strength and durability, and promotes industry progress.
