采用废旧胶粉和抗车辙剂对90号A级道路石油沥青进行双重改性，对比双重改性沥青混合料与SBS改性沥青混合料的高温性能、低温性能、水稳定性能，结果表明双重改性沥青混合料的高温性能优于SBS改性沥青混合料，低温性能略低于SBS改性沥青混合料、水稳定性能略高于SBS改性沥青混合料。总体而言，双重改性沥青混合料的路用性能可满足规范的最高要求，且其高温抗车辙性能显著。

Asphalt mixture was double modified by waste robber powder and anti-rutting agent. High and low temperature performance, water stability performance between SBS modified asphalt mixture and dou-ble modified asphalt mixture were contrasted. The results show that the high temperature performance of double modified asphalt mixture is better than that of the SBS modified asphalt mixture,the low tempera-ture performance of double modified asphalt mixture is a little less than that of the SBS modified asphalt mixture, the water stability performance of double modified asphalt mixture is a little better than that of the SBS modified asphalt mixture. Overall, double modified asphalt mixture can meet the highest require-ments of the specification, and high temperature anti-rutting performance is significantly.
