| 摘 要： | 路基土和粒料的回弹模量对沥青路面的结构力学响应有很大的影响,合理选择路基土和粒料的回弹模量能够延长沥青路面的使用寿命.鉴于此,在调研国内外路基土和粒料回弹模量相关研究成果的基础上,总结分析了含水量、材料级配、细料含量、最大粒径以及材料类型与颗粒形状对路基土和粒料回弹模量的影响,可为我国沥青路面设计提供一定的参考和借鉴.

| Abstract: | Resilient modulus of subgrade soil and aggregates have great influence on the structural mechanics response of asphalt pavement, reasonable choice of the modulus resilient can extend the life of asphalt pavement. Given this, based on the relevant research results at home and abroad, this paper summarized the influence of soil and aggregate modulus resilient by water content, the material grade, fines content, the maximum grain size, material types and particle shape. It can provide references for the design of asphalt pavement. |
