摘　　要：通过SBR改性沥青试验,考察改性沥青针入度、改性剂加入量、反应温度和交联剂等因素对SBR改性沥青粘韧性和韧性指标的影响。结果表明,SBRII-B的粘韧性性能比SBRII-A的粘韧性性能更有优势,可以通过复配SBS改性剂、提高反应温度和添加合适的的交联剂等方法改善SBRII-A的粘韧性性能。In this paper,the influence of the penetration of modified asphalt,the amount of modifier,reaction temperature and crosslinking agent on the viscotoughness and toughness of SBR modified asphalt was investigated through the experimental study on the preparation of SBR modified asphalt.The results showed that SBRII-B has more advantages in viscotoughness and toughness than SBRII-A.The viscotoughness and toughness of SBRII-A can be improved by compounding SBS modifier,increasing reaction temperature and adding appropriate crosslinking agent.
