摘　　要：通过正交设计方法,研究水泥乳化沥青混凝土的配合比,并进行水泥乳化沥青混凝土的性能试验。试验结果表明:黏土掺量是影响水泥乳化沥青混凝土抗压强度的主要因素,其次是青胶比,再次是水胶比;随着龄期增长,水泥乳化沥青混凝土强度及变形性能逐渐增加;早期抗压强度较低,后期强度增长较快,28 d抗压强度明显高于传统塑性混凝土;弹性模量较低,模强比低于500。期望促进水泥乳化沥青混凝土的理论研究和工程实践。By the orthogonal design method, the mix proportion of the emulsified asphalt concrete has been optimized and the performance test of the emulsified asphalt concrete has been conducted.Results show as follows：affect the emulsified asphalt concrete compressive strength of the main facts is the clay content followed by asphalt-binder ratio and water-binder ratio; as age increased, strength and deformation properties of the emulsified asphalt concrete increased gradually; the elastic module is relatively lower, modulus-strength ratio is less than 500.It is expected that the theoretical research and the engineering practice of the emulsified asphalt concrete will be promoted.
