摘　　要：根据细观力学模型,将水泥乳化沥青砂浆(CA砂浆)分解成多个层次的二元复合体系。通过借鉴二元复合体弹性模量计算模型逐层进行计算,建立了通过配合比参数计算CA砂浆弹性模量的方法,并对不同配合比的水泥沥青砂浆的弹性模量进行了计算,并与实验结果进行了比对,有较好的一致性,验证了该计算方法的合理性与有效性。Cement asphalt（CA）mortar was decomposed into the multiple levels of binary mixtures based on the micro mechanics model. According to a model of binary complex elastic modulus, a calculation method for CA mortar elastic modulus by mixing ratio parameters was proposed. This method was used to calculate the different mixing ratios, and the calculated results were similar to the experimental data, showing that the method is effective.
