沿海环境下胶粉沥青混合料抗水损害性能研究

Moisture damage of crumb rubber modified asphalt mixture in coastal area

通过浸水马歇尔试验和冻融劈裂试验,从氯盐溶液浓度、橡胶粉细度、浸泡时间三方面,探讨了橡胶粉沥青混合料的抗水损害性能,指出高盐及高湿环境对沥青混合料的性能有较大的影响。

From the immersion Marshall tests and freeze-thaw split test, the paper explores the anti-water damage performance of the rubber pow- der asphalt from the chloride solution density, fineness of rubber powder, and soaked time, and points out the high-salt and high-humidity has larger influence on the performance of the asphalt mixture.
