摘　　要：随着我国交通事业的发展,废旧沥青混合料再生技术已经普遍应用到我国公路建设过程中,工程经验表明,热再生沥青混合料高温性能优于普通沥青混合料,但其水稳性能却有所降低。因此,文章基于集料-沥青黏附理论,采用室内拉伸试验,研究了温度、沥青老化程度、集料类型、再生剂、水分等因素对集料-沥青界面黏结性能的影响,进而从微观层面解释了热再生沥青混合料水稳定性较差的原因。With the development of China’s transportation industry,the recycling technology of waste asphalt mixture has been widely applied in the process of highway construction in China.Engineering experience shows that the high-temperature performance of hot recycled asphalt mixture is better than that of ordinary asphalt mixture,but its water stability performance has decreased.Therefore,based on the theory of aggregate asphalt adhesion,this study uses indoor tensile experiments to study the effects of factors such as temperature,asphalt aging degree,aggregate type,rejuvenator,and moisture on the interfacial bonding performance of aggregate asphalt;Furthermore,the reason for the low water stability of hot recycled asphalt mixtures was explained at the micro level.
