摘　　要：稀浆表处在道路工程中的应用越来越广泛,通过探讨应用过程中存在的问题,分析稀浆表处结构和抗剪强度构成等性能的特殊性,提出稀浆表处集料颗粒排列理论、反粒子干涉理论和最佳和易性级配曲线理论,分析稀浆表处使用结合料的特殊性,提出了超粗型稀浆表处设计方法。结果表明:稀浆表处与车辙深度存在匹配关系;单层稀浆表处更适宜使用SBR改性乳化沥青;研究成果丰富了沥青路面的理论体系,并对工程实践具有切实的指导作用。The slurry surfacing is more and more widely used in road engineering.Through discussing the problems in the application process,analyzing the particularity of the slurry surfacing structure and shear strength composition,the theory of aggregate particle arrangement,anti particle interference theory and the theory of optimal workability grading curve are proposed,and the particularity of binder used in slurry surfacing is analyzed.The design method of super coarse slurry surfacing is developed.The results show that there is a matching relationship between the slurry surfacing and the rutting depth;SBR modified emulsified asphalt is more suitable for single-layer slurry surfacing;The research results enrich the theoretical system of asphalt pavement,and have a practical guiding role in engineering practice.
