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 mi...
