摘　　要：解决环氧树脂与沥青的相溶性问题是成功制备环氧沥青的关键技术之一,通过无固化剂环氧树脂与沥青混合液的离析试验确定了一种毒性小、相溶性好的相溶剂,采用电子扫描显微镜分析了相溶剂的增溶机理,并研究了相溶剂的掺量对环氧沥青拉伸强度和环氧沥青混凝土路用性能的影响。Solving the intermiscibility of epoxy resin and matrix asphalt is one of the key technolo- gy of producting successful epoxy asphalt that. The study developed a solubilizer with small toxicity and good intermisieibility by the segregation test to the mixture epoxy resin without solidifying agent and ma- trix asphalt, and then the solubilizing mechanism of solubilizer was analysed through a electronic scan- ning microscope, and the influence of the tensile strength of the epoxy asphalt mixture caused by the dos- age of the solubilizer was studied.
