摘要
本文对氧化石墨烯-玄武岩纤维复合改性沥青进行了针入度实验、软化点实验和测力延度实验,并且对比分析了氧化石墨烯-玄武岩纤维复合改性沥青与氧化石墨烯改性沥青、玄武岩纤维改性沥青之间的性能差异。研究结果表明:掺入复合改性剂和玄武岩纤维单配改性剂后,沥青的针入度指标随着掺入量的增加逐渐减小,软化点随着掺入量的增加逐渐增大,并且复合改性沥青的改性效果明显优于单配改性沥青的改性效果。
In this paper,the penetration test,softening point test,and force ductility test of graphene oxide-basalt fiber composite modified asphalt were carried out,and the performance differences between graphene oxide-basalt fiber composite modified asphalt and graphene oxide modified asphalt and basalt fiber modified asphalt were compared and analyzed.The results show that after adding composite modifier and basalt fiber modifier alone,the penetration index of asphalt decreases gradually with the increase of doping amount,and the softening point increases gradually with the increase of doping amount.The modification effect of composite modified asphalt is obviously better than that of single modified asphalt.
