广西地区不同岩性SMA-13沥青混合料性能研究

Study on Properties of SMA-13 Asphalt Mixture with Different Lithology in Guangxi Area

依托广西在建的高速项目,分别采用辉绿岩、玄武岩两种不同岩性的碎石进行SMA沥青混合料的设计,通过对比分析两种不同岩性集料的指标以及两种岩性的SMA沥青混合料的油石比、高温稳定性能、抗水损害性能、低温稳定性能、现场路用性能等指标,为广西地区因地制宜的选择SMA路面的碎石材料提供参考。

Based on the under construction highway project in Guangxi.this paper studied the highway performance of diabase and basalt gravels.The SMA asphalt mixture design was used for forming the two types gravels into mixtures.The properties of the two gravels and the highway performance of the two type mixtures were tested such as aggregate and bitumen binder ratios and high temperature performance,water stability and low temperature anti-cracking performance.It provides reference for the selection of suliable SMA pavements in Guangxi using local gravel materials.
