摘　　要：通过对传统改性沥青中改性材料缺陷的简单介绍,进而对沥青改性新材料展开了分析,之后以此为基础,分别探讨了超活化胶粉改性材料的制备,以及利用该材料制备改性沥青的工艺流程。最后通过相应的试验方法,对超活化胶粉改性材料的物理性能进行了分析,为进一步提升改性沥青性能提供支持。In this paper, the defects of modified materials in traditional modified asphalt are briefly introduced, and then the new asphalt modified materials are analyzed. Based on this, the preparation of super activated rubber powder modified materials and the technological process of using this material to prepare modified asphalt are discussed respectively. Finally, through the corresponding test methods, the physical properties of the super activated rubber powder modified materials were analyzed to provide support for further improving the performance of the modified asphalt.
