摘要
水泥灌浆沥青混合料(CGBM)是在重力作用下,通过在多孔沥青混合料中注入水泥基灌浆材料而制备的一种复合式路面铺装材料。在过去的几十年中,CGBM因其相对于柔性和刚性路面的诸多优点而备受关注。基于当前CGBM的研究现状,分析了CGBM的特点及设计流程,综合评述了集料级配、材料组成等对CGBM力学和路用性能的影响以及CGBM的微观力学分析,并对CGBM的应用现状和研究方向进行了展望。
Cement Grouted Asphalt Mixture(CGBM)is a composite pavement material prepared by injecting cement-based grout into porous asphalt mixture under the action of gravity.Over the past few decades,CGBM had attracted much attention due to its numerous advantages over flexible and rigid pavements.Based on the current research status of CGBM,this paper analyzes the characteristics and design process of CGBM,comprehensively reviews the effects of aggregate gradation,material composition,and other factors on the mechanical and pavement performance of CGBM,as well as the micro-mechanical analysis of CGBM.Additionally,this paper provides an outlook on the current application status of CGBM.
