摘要
采用溶剂法和热熔法对沥青进行改性研究.改性剂以SBS(苯乙烯 丁二烯嵌段共聚物)为主,同时掺加脱硫胶粉、热塑性树脂等物质.通过多次对比实验,对添加剂用量及其改性效果进行分析,得到使改性沥青性能最优的合理配比.
This paper focuses on the method of asphalt modification and several reasonable formulas of SBS modifier(styrene-butadiene copolymer).The modifcation of asphalt is often made by solvent method and direct blend method.Besides the anslysis of the blending time and stirring speed,other factors such as the amount of solvent in solvent method and the blending temperature of in direct blend method are also discussed.
