| 摘 要： | 分析了改性沥青设计方法,通过室内实验对橡胶SBS改性沥青路用性能进行了分析,得出了改性沥青及混合料高温、低温及耐久性均优于普通沥青及混合料;改性剂量在一定范围内（2%~6%）,随着掺入改性剂量的增加,改性沥青混合料的高温稳定性明显增强,但低温抗裂性在达到最大值后减小。

| Abstract: | The design methods of modified asphalt were analyzed. Through the indoor experiment, we analyzed the rubber SBS modified asphaltg performance,we know that modified asphalt and mixture at high temperature, low temperature and durability are better than ordinary asphalt and mixture. Modified dose range （2% - 6% ）, with the content of the modified dosage increasing, high temperature stability of modified asphalt mixture is obviously increased, but the low temperature crack resistance decreases after it reaches the maximum value. |
