摘要
通过相关室内试验,研究了石墨烯复合橡胶改性沥青混合料、SBS改性沥青混合料及橡胶沥青混合料的水稳性能、高温性能及低温性能。结果表明:相比其他两种沥青混合料,石墨烯复合橡胶改性沥青混合料具有更好的水稳性能、高温抗变形能力,低温破坏应变与SBS改性沥青混合料相当,并满足现行规范技术指标要求。
In this paper,the water stability,high temperature performance and low temperature performance of graphene composite rubber modified asphalt mixture,SBS modified asphalt mixture and rubber asphalt mixture are studied through relevant laboratory tests.The results show that compared with the other two kinds of asphalt mixtures,the graphene composite rubber modified asphalt mixture has better water stability,high temperature deformation resistance,low temperature failure strain is comparable to that of SBS modified asphalt mixture,and meets the technical requirements of the current specification.
