[Abstract]:Epoxy asphalt is mainly composed of epoxy resin, curing agent and asphalt. It is an irreversible thermosetting material with three-dimensional network structure. It not only has good mechanical properties, high temperature stability and adhesion. And has the good corrosion resistance and so on characteristic, completely changed the traditional asphalt high temperature plasticity characteristic. Based on the analysis of the tensile strength of epoxy asphalt, the optimum mass ratio of epoxy resin to curing agent is 1: 1. On the basis of the same quality of epoxy resin and epoxy asphalt, the tensile strength of epoxy asphalt is determined to be 1: 1. By adjusting the quality of epoxy resin system and analyzing the change of tensile strength and elongation at break of epoxy asphalt, the mass of epoxy resin system is determined to be 45%, and the mechanical test of epoxy asphalt is carried out. The results of Bush viscometer test and fluorescence microscope analysis show that the quality of epoxy resin system increases gradually and the tensile strength increases and the elongation at break decreases gradually on the basis of the constant mass of epoxy asphalt. When the mass of epoxy system is increased to 45%, the phase transition occurs in the epoxy asphalt system, the epoxy resin becomes a continuous phase for the first time, the asphalt is a dispersed phase, the viscosity of epoxy asphalt increases with the increase of reaction temperature, and the viscosity of epoxy asphalt increases at 150 鈩，
