摘要
水稳定性是影响冷补沥青混合料性能的主要指标之一。为了研究冷补沥青混合料水稳定性的影响因素,利用马歇尔残留稳定度这一指标对添加了石灰和使用不同标号沥青的混合料进行了评价。研究发现,添加石灰可以提高冷补沥青混合料的水稳定性,中标号的沥青更适用于冷补沥青混合料。
Water stability is one of the main indexes to influence the performance of cold patch asphalt mixture. In order to study the influence factors on the water stability of cold patch asphalt mixture, the article evaluates the mixtures added with the lime and the different grade asphalts by using this index of Marshall residual stability. The study shows that the added lime can improve the water stability of cold patch asphalt mixture, and the middle grade asphalt is more suitable for cold patch asphalt mixture.
