Laboratory performance of cold-mix asphalt using epoxy resin modified-asphalt emulsion

As a newly developed road material, epoxy resin modified-asphalt emulsion (ERMAE) shows great promise of being applied to cold-mix asphalt. In this paper, the cold-mix asphalt using ERMAE (hereinafter referred to as the Subject) is evaluated in terms of Marshall Stability, moisture resistance, high-temperature performance and low-temperature performance with a series of tests, all of which are proven satisfactory. Its Marshall Stability is approximately equal to that of the hot-mix asphalt, and far greater than the traditional cold-mix asphalt. Its moisture resistance has reached the requirement for the hot-mix asphalt. Its performance at low temperatures is similar with that of the hot-mix asphalt while the performance at high temperatures even matches that of polymer-modified hot-mix asphalt. Also it is found that its optimum laboratory performance comes with a dosage of 30% of curing agent.
