摘　　要：通过存储稳定性试验确定废塑料添加到沥青中的最大掺量,采用针入度、软化点、延度、黏度、车辙试验、浸水马歇尔试验、冻融劈裂试验、低温弯曲试验等对最大掺量废塑料改性沥青及混合料的性能进行研究。结果表明:废塑料添加到沥青中的最大掺量为6%;废塑料的掺入对沥青材料的高温性能改善明显;但降低了沥青的低温性能;废塑料的掺入能够明显提高沥青混合料的高温性能和水稳定性能,但降低了沥青混合料的低温性能和抗疲劳性能。The maximum amount of waste plastics added to asphalt is determined through storage stability test,and the performance of modified asphalt and mixture with the maximum amount of waste plastics is studied through penetration,softening point,ductility,viscosity,rutting test,immersion Marshall test,freeze-thaw splitting test,low-temperature bending test,etc.The results show that the maximum amount of waste plastics added to asphalt is 6%;The mixing of waste plastics can obviously improve the high-temperature performance of asphalt materials;However,it reduces the low-temperature performance of asphalt;The addition of waste plastics can significantly improve the high-temperature performance and water stability of asphalt mixture,but reduce the low-temperature performance and fatigue resistance of asphalt mixture.
