摘　　要：为分析水性环氧树脂对乳化沥青性能的影响,以自制基质乳化沥青为基础,加入不同掺量水性环氧树脂,制备水性环氧乳化沥青,在室内进行试验。结果表明,水性环氧树脂掺量的增加显著降低了蒸发残留物的针入度和延度,软化点则显著升高,延度变化尤为显著,水性环氧树脂掺量增加使蒸发残留物在高温条件下的抗变形能力显著增强,研究成果可为水性环氧乳化沥青的优化应用提供参考。To analyze the influence of waterborne epoxy resin on the performance of emulsified asphalt,waterborne epoxy emulsified asphalt was prepared by adding different amounts of waterborne epoxy resin to self-made base emulsified asphalt and conducting indoor experiments.The results showed that the increase in waterborne epoxy resin content significantly reduced the penetration and ductility of the evaporation residues,while significantly increasing the softening point,with particularly notable changes in ductility.The increase in waterborne epoxy resin content significantly enhanced the deformation resistance of the evaporation residues under hightemperature conditions.The research findings can provide a reference for the optimized application of waterborne epoxy emulsified asphalt.
