橡胶沥青混合料是一种节能、环保、减少“黑色”环境污染的新型路用材料,本研究主要通过冻融劈裂试验、弯曲试验、车辙试验和疲劳试验测定橡胶改性沥青混合料和基质沥青混合料的水稳性能、低温性能、高温性能以及疲劳性能,以此分析橡胶沥青路面在省道维修工程中的应用前景。结果表明:橡胶改性沥青路面高温性能、低温性能、水稳定性能以及抗疲劳性能较基质沥青混合料均有明显的提高,适用于省道维修工程。
Rubber asphalt mixture is a new type of road material with energy saving, environmental protection and reduction of “black” environmental pollution. In this study, the rubber modified asphalt mixture was mainly tested by freeze-thaw splitting test, bending test, rutting test and fatigue test And the asphalt mixture of the water stability, low temperature performance, high temperature performance and fatigue properties, rubber asphalt pavement in the maintenance of highway engineering application prospects. The results show that the rubber modified asphalt pavement has obviously higher high temperature performance, low temperature performance, water stability and anti-fatigue performance than the matrix asphalt mixture, which is suitable for the provincial highway maintenance project.
