掺加消石灰的沥青混合料抗水损害性能试验研究

Experimental research on asphalt mixture mixed with lime

结合盐通高速公路实际情况,采用冻融劈裂试验方法,对中上面层沥青混合料中添加消石灰、液体抗剥落剂进行了水稳定性试验比较,比较结果表明掺加消石灰后对改善沥青混合料的水稳定性有很明显的效果。根据研究结论,在盐通高速公路中下面层全线进行了推广,其长期应用效果将继续跟踪观测。

Combined with the practical Yah Tong expressway, using stress cracking method through freezing and thawing procedure, the thesis carries researches on anti-strip asphalt dosage, which includes liquid anti-strip asphalt dosage and lime. Results show that lime has clear effect to improve the anti-water stability of asphalt mixture. According to conclusion of the research, anti-strip dosage of lime has applied on the Yan-Tong expressway, and the long effect of the anti-strip lime is traced by the research group.
