摘　　要：研究了回收沥青的性能,采用再生剂对回收沥青进行再生,并检测了再生混合料的性能。研究结果表明,回收沥青表现出严重的硬化、脆化和粘稠,如不进行再生,则不可作为沥青胶结料使用,经再生剂再生后,回收沥青不仅基本性能恢复到新沥青水平,而且抗老化性能较高,再生混合料的性能也远超过标准的要求,可放心使用。The properties of deteriorated asphalt and reclaimed asphalt concrete recycled by reclaiming agent were studied. Results showed that deteriorated asphalt was so hardened, brittle and viscous that could not be used as a binder before recycled. By adding redaiming aget, the properties were recovered to a new level, and it had a good property in aging - resistant. The reclaimed asphalt concrete could be used since the properties were far above the requirements of standards.
