Cement emulsified asphalt mixtures are a kind of potential pavement material, but the adhesion between coarse aggregate and asphalt still needs to be studied. In this paper, a qualitative analysis method of the surface morphology of coarse aggregate was proposed and used to evaluate the surface morphologies of four kinds of coarse aggregate, including diabase, basalt, steel slag and recycled aggregate. The interface observation method, surface energy method and shear strength method were used to study the cohesiveness of the coarse aggregate and cement emulsified asphalt. At the same time, the immersion stability test and indirect tensile strength (ITS) test were carried out, and the water stability of the cement emulsified asphalt mixture was explored. The results show that the qualitative analysis method of coarse aggregate surface morphology is a convenient and practical method, and its evaluation results have high reliability. In addition, the surface morphology of the coarse aggregate has a positive correlation with the adhesion of the cement emulsified asphalt mixture, and it also has an indirect impact on the water stability of the mixture.

水泥乳化沥青混合料是一种潜在的铺装材料，但粗骨料与沥青的粘结性尚需研究。提出了一种粗骨料表面形态的定性分析方法，用于评价辉绿岩，玄武岩，钢渣和再生骨料四种粗骨料的表面形态。采用界面观察法，表面能法和剪切强度法研究了粗骨料与水泥乳化沥青的粘结性。同时进行了沉浸稳定性试验和间接拉伸强度（ITS）试验，探讨了水泥乳化沥青混合料的水稳定性。结果表明，粗骨料表面形态的定性分析方法是一种方便实用的方法，其评价结果具有较高的可靠性。另外，粗骨料的表面形态与水泥乳化沥青混合料的附着力呈正相关，对混合料的水稳定性也有间接影响。
