摘　　要：改性沥青的粘度和老化是影响其路用性能的两个重要因素。试验结果表明,SBS品种、环氧化SBS改性剂的环氧基质量分数和加入量、反应时间以及测试温度等条件都影响改性沥青的粘度。The viscosity and the aging of modified asphalt were two important factors to asphalt pavement service property. Asphalt was modified by epoxidized SBS. The viscosity and the aging of the modified asphalt were studied. The results indicated that the viscosity of the modified asphalt were influenced by characteristics, content, the mass fraction of epoxidized SBS and reactive time.

关 键 词：环氧化SBS 改性沥青 粘度 老化
