【摘要】 采用环氧化SBS改性镇海沥青,研究了改性沥青的针入度、软化点、延度的变化 规律,并探讨了环氧化SBS改性沥青的机理。实验结果表明,SBS牌号、ESBS改性剂的环氧 基质量分数和加入量以及反应时间等条件都影响改性沥青的三项指标。更多还原

【Abstract】 Asphalt was modified by epoxidized SBS. The fundamental properties (penetration, softening point, ductility) of the modified asphalt and modified mechanism were studied. The results indicated that the properties of the modified asphalt were influenced by characteristics, content , the mass fraction of epoxidized SBS and reactive time.更多还原
