中文摘要：

水泥-沥青-环氧树脂（CAE）复合胶结材料具有很好的粘结性能、高温稳定性以及柔韧性,适于钢箱梁桥面铺装材料的使用。通过路用性能研究及SEM微观形貌进行分析,结果表明,CAE混凝土中沥青与环氧树脂形成相互交织的连续网络结构,通过水泥联接。提出CAE的形成包括机械分散、互相作用、网络形成、强度发展4个过程。并通过实验验证了所提出的CAE微观结构和形成过程。

英文摘要：

CAE meet requirement for paving in steel bridge deck pavement materials,which possessing cohesive-ness to steel plate,good flexibility and high temperature stability.This paper used SEM to investigate the micro morphology of CAE：asphalt and epoxy present hydration net structure connected by cement.It inferred that the formation of CAE including four processes：dispersion,reaction,net structure forming,strength develop-ment,which was validated by proper experiment.
