摘　　要：对PPA与SBS复合改性沥青及其混合料进行了系统评价，结果表明:PPA与SBS复合改性，其沥青及混合料具有优良的高、低温性能，同时显著提高沥青的耐老化性能和热存储性能。PPA可替代部分SBS改性剂，其性能等同于或高于传统SBS改性沥青混合料，其最适宜掺量范围为0.75%~1.5%。The system evaluation is made on PPA + SBS compound modified asphalt and its mixture. The result shows that : PPA + SBS compound modified asphalt and mixture are with good high - temperature and low -temperature performance, which can remarkably improve the ageing - resistant performance and heat storage performance of asphalt at the same time. PPA can replace part of SBS modifying agent, whose performance is equivalent to or superior to that of traditional SBS modified asphalt mixture, and the most appropriate range of mixing amount is 0. 7 5 % ?1.5 % .
