路面材料在车轮荷载和环境因素的作用下所表现出的力学性质,对路面的使用性能和使用寿命起决定性作业。对路面材料力学性质的分析和认识,有助于设计出符合使用要求的路面结构。现着重讨论各种材料路面结构设计相关的两个特性,即变形特性、强度特性,以及表征这些性质的指标和确定方法。
The mechanical properties of pavement materials under the action of wheel loads and environmental factors play a decisive role in the serviceability and service life of the pavement. Analysis and understanding of the mechanical properties of pavement materials help to design pavement structures that meet the requirements of the application. The two characteristics related to the pavement structure design of various materials are emphatically discussed, that is, the deformation characteristics and the strength characteristics, as well as the indexes and determination methods for characterizing these properties.
