粗集料对沥青混合料路用性能的影响研究

Study on Impacts About Coarse Aggregate to Asphalt Mixture Performance

集料是混合料结构形成的决定性成分,其岩性性质、物理力学指标以及外观形状的差异,对于混合料表层抗滑特性的影响,体现在路面微结构和宏观构造深度的形成和保持方面;同时也将导致混合料的温度稳定性和疲劳耐久性方面的性能发生很大的变化,文中对粗集料对沥青混合料性能的影响进行了系统试验研究,得出了相应结论。

Aggregate is the decisive composition of the mixture material structure, It’s rock nature, physics mechanics index and differences of external appearance form, the impacts about the resist slippery characteristic on the mixture top layer, these are reflected in the forming and keeping of the road surface micro-structure and macroscopic structure depth. It also will cause temperature stability and performance of tired durability of the mixture to change very greatly. This article has carried on systematic experimental study to the impact that is about the coarse aggregate to asphalt mixture performance.
