| 摘 要： | 通过对不同类型的改性沥青进行软化点及车辙试验并进行对比，发现SASOBIT及PE能够大幅度改善沥青的高温性能，而EVA对沥青的高温性能提高不大；软化点很难对不同类型的改性沥青的高温性能进行评级和分类，但软化点大幅度提高时，车辙试验的动稳定度也相应会有大幅度提高。

| Abstract: | Based on the results of softening point test and rutting test to different types of modified asphalt,it was found that SASOBIT and PE modifier can apparently improve the high temperature performance while EVA does not.It is impossible to grade the high temperature performance of modified asphalt according to different sofling point classes,but the Dynamic Stability (DS) can apparently improve with soft point. |

| Keywords: | Modified asphalt Soft point Rutting test High Temperature performance |
