摘　　要：基于室内试验,通过与普通乳化沥青混合料相比较,分析了水泥-乳化沥青混合料 的强度形成机理;分析了水泥、乳化沥青两种拈结料在混合料中的作用;研究了水泥-乳化沥 青混合料配合比设计中的试验方法。结果表明:水泥的加入使得乳化沥青混合料的技术性能显 著提高,水泥改变了混合料的内在结构,表现出异于普通乳化沥青混合料的特点;提出的再修 正马歇尔试验方法更适合于水泥-乳化沥青混合料。同时提出用刚化系数K来控制水泥-乳 化沥青刚度的增加。Based on indoor experiments and comparison with emulsified asphalt mixture, strength mechanism of cement-emulsified asphalt mixture was analyzed, and the effects of cement and emulsified asphalt in mixture were analyzed. Also the experiment method of cement-emulsified asphalt mixture for mix design was studied. The results showed that cement has improved greatly technical capacities of mixture and it changes its structure, then it behaves different characters with emulsified asphalt mixture. Re-corrected Marshall experiment method to cement-emulsified asphalt mixture. At the same stiffness of cement-emulsified asphalt mixture was that the author brought forward was more suitable time, Stiffness Coefficient K to control addition of put forward.
