Abstract Epoxy asphalt is a kind of orthotropic steel bridge deck pavement materials with an excellent balance among high temperature performance, low temperature performance and fatigue performance. Due to the disparities between epoxy resin and petroleum asphalt in solubility parameters, dielectric constant and density, the improvement of compatibility between them is the precondition for the development and mass production of high performance steel bridge deck pavement materials. We herein summarize the progress in the compatibility research of epoxy asphalt from the perspectives of three feasible routes to compatiblizing epoxy asphalt, i.e. maleic anhydride modification, selecting highly compatible curing agent and adding compatibilizer. The paper also discusses the unresolved problems with a suggestion of focusing on promoting the fatigue resistance, weatherability and construction convenience in the next stage.
