摘　　要：用“固化剂乳化型”水性环氧体系作为新型聚合物改性剂制备水性环氧改性乳化沥青,以其作为胶结料应用于微表处罩面能有效改善常规微表处存在的耐久性差、耐候性欠佳、抗剪切破坏能力不足等缺陷,结果表明:水性环氧固化体系的掺入,使乳化沥青体系具备更好的力学强度;水性环氧固化体系能有效提升乳化沥青稀浆混合料的耐磨耗性能,综合考虑性能和成本,确定10%为水性环氧乳液的最佳掺量。The waterborne epoxy modified emulsified asphalt is prepared by using curing agent emulsifying-type waterborne epoxy system for curing agent as a new polymer modifier.Its application as binder in micro surface coating can effectively improve the defects of poor durability,poor weather resistance and insufficient shear failure resistance of conventional micro surface.The results show that:the addition of waterborne epoxy curing system can make the emulsified asphalt system have better mechanical strength;the waterborne epoxy curing system can effectively improve the wear resistance of the emulsified asphalt slurry mixture.Considering the performance and cost,10%of the waterborne epoxy emulsion is the best mixing amount.
