摘要
通过浸水马歇尔试验和冻融劈裂试验,对不同级配大粒径沥青稳定碎石混合料的水稳定性进行对比试验研究。结果表明,冻融劈裂试验更能体现出不同级配混合料水稳定性的差异,可较好地模拟混合料水损坏过程,是评价大粒径沥青稳定碎石混合料水稳定性的优选方法。
Based on the immersion Marshall stability test and freeze-thaw splitting test, the water stabilities of large-sized asphalt treated base mixtures with different aggregates gradation are experimented comparatively. The results show that the freeze-thaw splitting test can better show the differences of the water stabilities of the mixture and simulate the water damage process of these different gradations. The freeze-thaw splitting test is also the best way to evaluate the water stability of asphalt treated base.
