摘　　要：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 gyratory compactor is used to form the specimens. The improved Superpave design method is used to design the asphalt mixture of anti-crack layer. The single-deck rutting test and double-deck rutting test are used to analyze the high temperature performance of rubber asphalt anti-crack layer. The result shows that the improved Superpave design method is suitable to design the asphalt mixture of anti-crack layer. The high temperature performance of rubber asphalt anti-crack layer is not good, but the influence is limited on the high temperature performance of pavement structure. The high temperature performance of pavement structure of rubber asphalt anti-crack layer is good and there is a large space to upgrade.
