Research on Performance of Epoxy-Rubber Modified Asphalt and Its Mixture

The rubber asphalt is compound modified with epoxy resin,the basic performance of epoxy-rubber modified asphalt:softening point,elastic recovery and so on,also its production process are mastered;the optimal mixing amount of epoxy resin and the best mix proportion of epoxy-rubber modified asphalt mixture are determined by asphalt test.Furthermore,the properties of asphalt mixture are tested by marshall test and rutting test.These experiments test the stability under high temperature regimes,low temperature crack resistance and anti-water damage property of the epoxy-rubber modified asphalt mixture,demonstrat it had the advantage of compound modify.
