摘　　要：先后采用再生剂、SBS改性沥青、再生剂与SBS改性沥青对路面不同层位的回收旧沥青进行再生处理,制备不同种类的再生沥青。三大指标结果显示,相较于其他面层,上面层老化程度更高,但应用再生剂和SBS改性沥青共同处理后,各面层回收旧沥青的性能基本恢复到同一水平。红外光谱与激光共聚焦结果显示,再生剂仅起到沥青组分调节作用,而无法补充氧化的SBS改性剂。Different types of recycled asphalt are prepared by successively using regenerants,SBS modified asphalt,and a combination of regenerants and SBS modified asphalt to recycle old asphalt from different layers of the road surface.The results of the three major indicators show that,compared to other surface layers,the aging degree of the upper layer is higher.However,after the joint treatment of regenerants and SBS modified asphalt,the performance of the recycled old asphalt in each surface layer is basically restored to the same level.The results of infrared spectroscopy and laser confocal microscopy show that,the regenerant can only play a role in regulating the asphalt components and cannot supplement the oxidized SBS modifier.
