沥青混合料水稳性试验方法

Method of asphalt mixture immersion stability test

通过对不同空隙率条件下的沥青混合料进行浸水马歇尔试验、冻融劈裂试验 ,比较了各水稳性试验方法在评价沥青混合料水稳性时的优劣 ,并对原因进行了分析。最后对沥青混合料的水稳性试验方法及评价指标进行了探讨。

On the base of immersion Marshall test and freeze thaw split test in different air voids in asphalt mixture,the differences of each method in evaluating asphalt mixture immersion stability are compared,and the reasons are analyzed,furthermore,the immersion test method and evaluation index of asphalt mixture are discussed. 9 tabs,3 refs.
