摘　　要：沥青热再生技术在国内得到越来越多的重视,但是对于热再生过程中旧沥青结合料转移情况的认识还很不够,本研究针对不同的再生条件,即旧料的预热温度、是否掺加再生剂、再生剂的品种和旧料的沥青膜厚,进行初步的旧沥青转移模拟试验研究,以帮助深入理解沥青热再生技术。The asphalt hot-recycling technology has gained more and more recognition in China, but the knowledge about aged asphalt cement transfer circumstance in the asphalt hot-recycling process is very little. This study focuses on different recycling conditions which include aged mixture temperature, rejuvenating agent category and asphalt membrane thickness. This preliminary aged asphalt transfer simulation experiment will help us deeply understand hot-recycling technology.
