摘要
废橡胶粉改性沥青(CRMA)技术能较好地改善沥青路面的高低温性能,为进一步提升路用性能和解决储存稳定性问题,通常在基质沥青中同时加入其他改性剂进行复合改性。本文介绍了近年来国内外应用较多的苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)、多聚磷酸(PPA)和石墨烯等改性剂与废橡胶粉对沥青进行复合改性的研究成果,分析总结了复合改性沥青的优越性和存在的不足,为更深入的复合改性沥青技术研究提供一定的指导作用。
Crumb rubber modified asphalt(CRMA)technology can improve the high and low temperature performance of asphalt pavement.In order to further improve the road performance and solve the problem of storage stability,other modifiers are usually added to the matrix asphalt for composite modification.This paper introduces the research results of composite modification of asphalt with crumb rubber and modifiers such as styrene-butadiene-styrene block copolymer(SBS),polyphosphoric acid(PPA)and graphene,which are widely used in home and abroad in recent years.The advantages and disadvantages of composite modified asphalt are analyzed and summarized,which provides some guidance for further research on composite modified asphalt technology.
