Epoxy bitumen is a special type of thermosetting binder designed for flexible pavements, and could increase the durability and lifespan of pavements. In this study, a series of viscosity tests were performed to investigate various conditions, i.e. temperature, shear rate and dilution level, on the curing behavior of epoxy bitumen. The results show that curing rate of epoxy bitumen increase with temperature; high shear rate would interfere the formation of crosslinks in epoxy bitumen, resulting in the a negative effect on curing rate; diluting epoxy bitumen by a base bitumen is an effective way to control the curing rate and reduce the materials cost. Considering the workability and durability of paving materials, it recommends that dilution level is 25%, mixing rate is 20 RMP, curing temperature is 130 °C, and the pavement construction should be finished with 5 hours.
