摘　　要：选用目前应用最为广泛的两种温拌剂:Sasobit和Evotherm,从微观角度出发,通过组分试验和差热试验对加入这两种温拌剂的温拌橡胶沥青的化学组分进行分析,进而研究其降粘机理,研究结果为温拌橡胶沥青的降粘机理提供了理论基础,促进了温拌橡胶沥青的推广使用。By starting from the microscopic point of view,this paper selects two warm mix agents：Sasobit and Evotherm,which are most widely used at present,to make a deep analysis about the chemical components of the warm mix rubber asphalt which have been added into these two warm mix agents by component test and differential thermal test,so that the viscosity reduction mechanism can be further studied. The results will provide a theory basis for the viscosity reduction mechanism of the warm mix rubber asphalt,and promote the use of the warm mix rubber asphalt.
