摘要

目前改性沥青在使用过程中存在着路面早期病害如车辙、水损坏、易老化等问题,严重影响沥青路面的使用寿命。石墨烯是碳的同素异形体,为排列成六角形晶格的单层碳原子,具有优异的力学和热学性质,其结构特性对解决沥青路面存在的问题提供了新的思路。系统地总结了石墨烯在沥青改性中的最新研究成果,包括石墨烯对沥青及其混合料性能的影响,石墨烯改性沥青的制备方式、原料性质等影响因素,并总结了国内外石墨烯改性沥青路面在工程应用中的最新进展。最后,对石墨烯在沥青改性应用方面存在的技术难点,以及产业化方向进行了讨论和展望。

Abstract

At present,there are still problems in the early diseases of the modified asphalt such as rutting,water damage and aging,which seriously affect the service life of the asphalt pavement.Graphene,an allotrope of carbon with a single layer of carbon atoms arranged in a hexagonal lattice,which has excellent mechanical and thermal properties,has been considered as an effective additive to improve the properties of asphalt.Herein,Recent research progress of graphene modified asphalt was reviewed for the first time including the influence of graphene on the performance of asphalt and its mixture,the preparation method of graphene modified asphalt and the influence of raw material properties.In addition,The latest application of graphene modified asphalt pavement engineering in domestic and foreign was summarized.Finally,current challenges and future perspectives of graphene applied in asphalt pavement were also discussed and proposed respectively.
