In order to know the influence of rubber powder on properties of epoxy asphalt and its mixture, various tests including viscosity, tensile, Marshall, rutting and bending beam strength were carried out for the crumb rubber modified epoxy asphalt under 2%10% rubber powder levels by mass. Based on these results, the reserved time of modified epoxy asphalt is shortened slightly, while the fracture elongation increases. The elongation of 6% rubber powder modified epoxy asphalt is up to 261%. Besides, the modified epoxy asphalt has better high temperature stability and its low temperature brittleness also improves. 4%, 6% crumb rubber modified epoxy asphalt mixtures show higher strength and better deformation capacity at low temperature.
