| 摘 要： | 沥青路面的水损坏是路面早期破坏现象之一,它的出现严重地影响了沥青路面的耐久性和使用寿命。通过室内模拟试验来研究水位对沥青混合料水稳定性的影响,同时对掺加熟石灰抗剥离剂的改善效果加以评价。试验结果表明,水位、沥青混合料试件的厚度以及加载时间对沥青混合料的水稳定性有着显著的影响,沥青混合料掺加熟石灰后其抗水害性得到明显提高。

| Abstract: | Moisture damage is one of asphalt pavement failure phenomenon, it can seriously affect the durability and life of asphalt pavement. The effect of water on moisture stability of asphalt mixture was studied by simulated test in the laboratory, and the performance of asphalt mixture with hydrated lime additive was analyzed. The results show that the effect of water level, asphalt pavement thickness and loading time on moisture susceptibility of asphalt mixture is very significant, the moisture stability of asphalt mixture with hydrated lime can be improved remarkablly. |
