| 摘 要： | 以往研究表明岩沥青可以显著提高沥青路面的高温抗车辙性能、抗水损坏性能和抗老化性能,明显改善沥青路面的路用性能,延长道路使用寿命,但随着岩沥青品种增多,性能不一。本研究对七种岩沥青15%掺量改性沥青用于AC-20混合料进行车辙试验、冻融劈裂试验、15℃动态模量试验、60℃动态模量试验,对其试验结果进行分析比较,得出不同岩沥青改性沥青的使用性能变化情况,为岩沥青的选择提供参考。

| Abstract: | Previous studies showed that the rock asphalt could significantly improve the asphalt pavement performance,such as the resisting rut at high temperature,the resisting water damage and anti - aging.The rock asphalt could also extend the service life of road,but the performance differed with the kinds of rock asphalt. In this paper,by using the seven kinds of rock asphalt,the mixture performance test such as rutting test,freeze-thaw splitting test,15℃dynamic modulus test,60℃dynamic modulus test had been done. The performance of modified asphalt mixture adding rock asphalt was analyzed.The result showed that the performance of rock asphalt mixtures changed and a reference for rock asphalt selection was provided. |
