Characterization of paving materials has a central role in the implementation of mechanistic-empirical design methods. Characterization encompasses the suite of laboratory and in-situ tests and fundamental material models required to fully reproduce the material response at the various loading and environmental conditions. Moisture effects can be observed in bound and unbound layers of asphalt and concrete pavements. The scope of this proposal is limited to asphalt concrete materials of the predominant types used in Manitoba and the prairie region.

铺装材料的表征在机械经验设计方法的实施中起着核心作用。表征包括一套实验室和现场测试以及基本材料模型，这些模型是在各种载荷和环境条件下完全再现材料响应所需的。在沥青和混凝土路面的结合层和非结合层中可以观察到水分效应。本建议书的范围仅限于马尼托巴和草原地区使用的主要类型的沥青混凝土材料。
