| 摘 要： | 为使改性沥青的技术性能有所提高,在工程应用中既能增加其路用性能,减少路面易产生的车辙、开裂、坑槽等早期破坏,又能减少养护次数,节省工程费用,进行了改性沥青配方的设计优化。从基质沥青与改性剂的配伍性、改性沥青的热储存稳定性和改性沥青的性能三大方面进行研究,通过在选取的三种AH-70重交石油沥青中掺加三种SBS改性剂(YH761、YH791-H、道改2号)和两种稳定剂(wdj、WT),对改性沥青的主要技术性能指标(针入度指数、软化点、5℃延度等)进行综合比选,从而得出每种基质沥青最适合的改性剂和稳定剂及其最佳掺配量,使改性沥青性能最优,可从根本上解决沥青面层高、低温稳定性和局部损坏等问题,从而延长路面使用寿命。
