Study on the Road Performance of Epoxy Emulsified Asphalt Mixture

Abstract

Again modified Marshall test method was adopted for ratio design in the premise of preparation of waterborne epoxy resin modified emulsified asphalt (epoxy emulsified asphalt for short), the road performance of epoxy emulsified asphalt mixture was evaluated from aspects of initial strength, molding strength, high temperature performance, low temperature performance and water stability, which were compared with that of matrix asphalt mixture and SBS modified asphalt mixture. Results show that the molding strength of epoxy emulsified asphalt mixture reaches up to 13.2kN, which is far bigger than that of matrix asphalt mixture and SBS modified asphalt mixture. Dynamic stability of epoxy emulsified asphalt mixture meets the requirements of high temperature stability of hot mix modified asphalt mixture, low temperature stability and water stability are approximately equal with ordinary hot mix asphalt mixture.
