Application of Gravelly Asphalt Concrete SAC-10 in Pavement Maintenance |
| |
| Abstract: | Based on the maintenance project in 2015 of asphalt pavement of F Highway in Henan province, the treatment plan and mixture composition design of the gravelly asphalt concrete SAC-10 thin layer overlay were carried out, and the technical condition of the test section pavement was tested and analyzed for 5 consecutive years. The results show that: the gravelly asphalt concrete SAC-10 can be used for continuous road sections with a pavement damage rate DR of 0.4 %～2.0 %, limited to the shallow layer disease of 1 to 3 cm on the upper layer, and a good combination of surface layers; Based on the principle of coarse aggregate forming a skeleton and a dense filling of fine aggregates, the designed gravelly asphalt concrete SAC-10 mixture can meet the road performance requirements of the asphalt pavement maintenance thin layer overlay. |
