摘　　要：运用熔融共混工艺,将废旧胶粉与废旧聚乙烯(PE)以及少量SBS、助剂混炼得到热塑性弹性体沥青改性剂(TPE),对其进行荧光显微(FM)与红外光谱(IR)分析发现,熔融共混过程以物理作用为主;将所得沥青改性剂加入基质沥青进行改性,常规技术指标测试结果表明,沥青的性能均有大幅提高;利用原子力显微镜对基质沥青、TPE改性沥青进行对比分析,TPE合金的加入造成的沥青质聚集是沥青性能得以改善的重要原因。Using the method of melting blending,it get three rubber-plastic alloy of Thermoplastic Elastomers （TPE）（TPE2,TPE4,TPE6）.After getting TPE,we characterize the TPE alloy by IR and FM,concluding that the melt blending process of preparing TPE is dominated physically;then,we use the TPE to modifify the base asphalt,simultaneously,getting the conventional indexes,which showed the greatly improvement;we al-so use AFM to contrast the surface of asphalt and modified asphalt as a result of a great change of asphalt after modifying,however,we owe this phenomenon to the influence of modifier on asphaltenes.
