摘　　要：为明确石墨烯类材料改性沥青性能的研究现状,通过查阅国内外相关研究文献,对比分析各种不同石墨烯类材料以及制备参数对沥青性能的影响。结果表明:石墨烯、纳米石墨片和氧化石墨烯能够改善沥青的微观形貌和路用性能,提高沥青的使用寿命,减少沥青的维护成本。不断优化改性沥青制备参数,探索新型材料改性沥青机理,不仅有助于促进道路沥青新技术的推广应用,还可以降低能量消耗、减少污染物与碳排放,为道路工程的发展提供新思路。To clarify the research status of modified asphalt properties with graphene materials,relevant research literature in China and abroad was consulted to compare the effects of various graphene materials and preparation parameters on asphalt.The results show that graphene,nano graphite sheets,and oxidized graphene can improve the microstructure and road performance of asphalt,increase the service life of asphalt,and reduce the maintenance cost of asphalt.Continuously optimizing the preparation parameters of modified asphalt and exploring the mechanism of modified asphalt with new material not only help the promotion and application of new road asphalt technologies but also reduce energy consumption,pollutants,and carbon emissions,providing new ideas for the future development of road engineering.
