Abstract: In order to get better performance of modified asphalt, more and more material is used as a modifier, also the new evaluation standards and methods and other areas of new chemical analysis method was also used to more complete and accurate evaluation of modified asphalt performance. The research status and progress of modified asphalt at home and abroad are summarized, and the general situation of various modified asphalt are introduced from the aspects of modification mechanism, influence factors and evaluation method, and the development direction of the modified asphalt is summarized.
