摘　　要：水泥乳化沥青混凝土是两种材料性能特点整合的一种新型路面材料,研究通过改变水灰比及乳化沥青用量对水泥乳化沥青混凝土的力学性能影响进行测试分析,结果显示:水泥乳化沥青混凝土强度随着用水量及沥青含量的增加而降低,具有明显的规律,当乳化沥青∶水泥=0.5时,降低幅度最大;同时结合SEM技术微观测试分析,乳化沥青残留物、水化产物和集料形成空间网络结构是影响其强度的主要原因。Cement emulsified asphalt concrete is a new kind of pavement material by integration of the two materials; performance characteristics. The research is proceeded by changing the water-cement ratio and asphalt content to the mechanical properties of the cement emulsified asphalt concrete and the test analysis results show that the strength of cement emulsified asphalt concrete decreases with the amount of water and bitumen content increased and the rule is obvious. When the ratio of emulsified asphalt, to cement is equal to 0. 5, it has the largest reduction; the space network structure of emulsified asphalt residues, hydration products and aggregates are the main reasons to affect its strength combined with the SEM technology micro--test analysis.
