摘　　要：分析比较了4种评价沥青混合料水稳定性评价方法即浸水马歇尔试验、冻融劈裂试验、沥青路面分析仪浸水车辙试验和朱丽叶试验的优缺点和试验条件.从试件性能的稳定性、试验模拟的环境条件、评价指标的有效性而言,沥青路面分析仪浸水车辙试验最好,朱丽叶试验次之,冻融劈裂试验第三,而浸水马歇尔试验最差.但从试验方法的可操作性而言,沥青路面分析仪浸水车辙试验最差.通过不同评价指标的相关性分析,研究不同试验方法内在区别和联系,从而为实际工程运用提供一些参考.A comparative study is carried on 4 evaluation methods for moisture susceptibility of asphalt mixture, including immersion marshall test, freeze-thaw splitting test, asphalt pavement analyzer （APA） rutting test in water and duriez test from the perspectives of their advantages, disadvantages and suitability. According to the stability of specimens, the simulation circumstance and evaluation index validity, APA rutting test in water is the best way and the duriez test comes in the second, the third is freeze-thaw splitting test and immersion marshall test is the worst way. The internal relations of different tests are studied on the basis of the analysis of correlation of different evaluation indexes, which provides some profitable reference in practical engineering application.
