摘要
分析了现行规范中关于级配碎石材料组成设计及技术指标方面存在的问题,并根据级配碎石的损坏特点以及用于不同的路面结构层的力学分析,提出了以CBR值及抗剪强度为强度设计指标的配合比设计方法,同时提出了建议的设计步骤以及设计工程实例。
This paper analyzes a few problems on the existing norms regarding the composition design and technical indicators of graded macadam, and based on the characteristics of the damage and the mechanical analysis of the surface structure on different layers of Graded macadam, we proposed a new strength design method by using CBR and shear strength values as references. Accordingly, we also provide design processes and examples in accordance with the proposed new design.
