摘　　要：综合利用水泥与沥青和环氧树脂粘附性好,环氧树脂温度稳定性好、粘接强度高及沥青材料粘韧性好的特点,研究水泥、沥青、环氧树脂组成比例与水泥-乳化沥青-水性环氧树脂胶浆(CAE)性能之间的关系,确定原材料的最佳比例,同时研究CAE胶浆的微结构。结果表明:水泥的最佳用量为A/C=2,水性环氧树脂的最佳用量为A/E=5/3;CAE胶浆的动稳定度达到35802次·mm-1,冻融劈裂强度比大于90%,与钢板粘结强度达到0.84 MPa;沥青网络与环氧树脂网络依靠水泥连接,水泥起到连接介质的作用。Comprehensive utilization of the characteristic, which the adhesion of cement is good with epoxy resin and asphalt, the temperature stability and bonding strength of epoxy resin is excellent, and the toughness of asphalt is good, the relationship between the radio of cement, asphalt and epoxy resin with the performance fo cementasphalt-epoxy mortar （ CAE ） was researched. On this basis, the optimal proportion of cement, asphalt and epoxy resin was confirmed. In addition, the mierostructure of CAE was researched. The results show that, the best dosage of cement is A/C= 2, the best dosage of waterborne epoxy is A/E= 5/3. The dynamic stability of CAE is 35802 times·mm-1 , the TSR of CAE is greater than 90%, the bonding strength of CAE with steel plate is 0. 84 MPa. The asphalt network and epoxy resin networks rely on cement connection; cement plays a connecting role of the media.
