Research on the design method of material mix ratio for rapid repair of high-grade asphalt pavement

Rapid repair of materials;  Mix ratio design;  Asphalt pavement

Through a large number of indoor tests, the preparation principle of rapid repair materials is analyzed in detail, the design method and steps of the mix ratio of rapid repair materials are proposed, and the rapid repair materials that can meet the requirements of looseness and compaction at the same time are prepared. The results show that in order to prepare a reasonable rapid repair material, it is necessary to select the appropriate ore gradation and mineral powder content, minimize the amount of diesel fuel in the asphalt liquid, and appropriately increase the content of SBS in the rapid repair material.
