As a novel green and eco-friendly road material,waste plastic modified asphalt can not only reduce environmental pollution,but also improve the road performance of asphalt,and its rheological properties have an important impact on the high and low temperature performance of asphalt pavement.Therefore,the use of rheological performance evaluation indicators to analyze the impact of waste plastics on the performance of modified asphalt has become the focus of future research.The classification and modification methods of waste plastic modified asphalt were summarized.The evaluation methods and indexes of high and low temperature rheological properties of waste plastic modified asphalt(dynamic shear test,multi-stress creep recovery test,zero shear viscosity,bending beam rheological test,direct tensile test)were comprehensively analyzed.The shortcomings of different evaluation methods and indexes of rheological properties were analyzed.Finally,the application prospect of rheological indexes in waste plastic modified asphalt was prospected.
