| 摘 要： | 在SBS改性沥青混合料、PR改性沥青混合料、RS改性沥青混合料车辙试验结果的基础上,分别进行了3种混合料的三轴重复荷载试验、三轴静态蠕变试验和动态模量试验,并对试验结果进行了对比分析,发现动态模量试验结果可以正确表征不同改性类型混合料抗永久流动性能的优劣,并与动稳定度有着很好的相关性,本试验结果可以用作沥青路面设计规范的修订参考。

| Abstract: | Based on the rut test results of SBS modified asphalt mixture,PR modified asphalt mixture and RS modified asphalt mixture,through triaxial repeated load test,triaxial static creep test and dynamic modulus test of the three kinds of mixture,this paper compared and analyzed the test results, found that the dynamic modulus test results could correctly characterize the resistance to permanent flow properties of different modification types mixture,and had a good correlation with the dynamic stability.The test results could be used as a revision of the reference for the asphalt pavement design specifications. |
