摘　　要：公路路面施工普遍需要应用到沥青混合料,沥青混合料在使用过程中会面临老化及破坏、裂缝和变形等各种问题及挑战。对公路混凝土路面沥青混合料进行水稳定性试验能确保公路的安全性、耐久性,确保路面材料的合理选用和质量控制,同时检测结果也可用于评估路面的使用寿命和维护周期。以某公路工程为研究对象,设计了3种沥青混合料,并对其进行了冻融劈裂试验,根据试验得出取孔隙率7%来评价水稳定性能。Asphalt mixture is widely used in highway pavement construction.Asphalt mixture will face various problems and challenges such as aging,damage,cracks and deformation during use.The water stability test of asphalt mixture on highway concrete pavement can ensure the safety and durability of highway,ensure the reasonable selection and quality control of pavement materials,and the test results can also be used to evaluate the service life and maintenance cycle of pavement.Taking a highway project as the research object,three kinds of asphalt mixture were designed,and the freeze-thaw splitting test was carried out.According to the test,the porosity of 7%was obtained to evaluate the water stability.
