摘要
以5.0%SBS改性的50号道路石油硬质沥青为结合料,采用旋转压实技术,设计了一种Superpave20沥青混合料。试验结果表明:所设计的混合料水稳性能、低温性能和可压实性能优良,特别是高温性能突出,较高模量沥青混合料的高温性能更优。
A novel Superpave20 mixture was prepared by gyratory compaction with AH- 50 asphalt modified by 5.0%SBS as the binder.The results show that the mixture performs well in water stability,low temperature performance and compatibility,especially in high temperature properties.It has better high temperature performance than high modulus asphalt mixture.
