Abstract
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 increased with temperature; high shear rate would interfere the formation of crosslinks in epoxy bitumen, resulting in a negative effect on curing rate; diluting epoxy bitumen by a base bitumen was an effective way to control the curing rate and reduce the material cost. Considering the workability and durability of paving materials, it is recommended that dilution level of epoxy bitumen is 25%, mixing rate is 20 r/min, curing temperature is 130 ℃, and the pavement construction should be finished within 5 hours.
