运用旋转压实仪成型试件,采用改进的Superpave设计方法进行抗裂层沥青混合料设计,通过单层车辙试验和双层车辙试验分析橡胶沥青抗裂层高温性能。结果表明:改进的Superpave设计方法适合抗裂层沥青混合料设计;橡胶沥青抗裂层高温性能不足,但对路面结构的高温性能影响有限;橡胶沥青抗裂层路面结构的高温性能良好并有很大的提升空间。
The rotary compaction instrument was used to shape the test piece. The improved Superpave design method was used to design the crack resistant asphalt mixture. The single layer rutting test and double layer rutting test were used to analyze the high temperature performance of the rubber asphalt crack resistant layer. The results show that the improved Superpave design method is suitable for the design of anti-crack asphalt mixture. The high temperature performance of rubber asphalt crack-resistant layer is not enough, but it has a limited impact on the high temperature performance of pavement structure. The high temperature performance of rubber asphalt crack- Great room for improvement.
