To evaluate the rheological and mechanical performance of warm-mixed EA/SBS blended asphalt(hereinaf-ter referred to as EA/SBS),the viscosity growth behaviour,rutting resistance,low-temperature crack resistance and ten-sile properties of EA/SBS binder were tested and evaluated.Results show that the viscosity growth characteristics of EA/SBS are more sensitive to the mixing temperature.Under the condition of 120 ℃,the EA/SBS with a 1∶1 mixing ratio has a longer retention time of 85 minutes.Increasing the content of SBS modified asphalt can improve the low-temperature crack resistance of EA/SBS.When the mixing ratio is 1∶1,the SHRP grading is PG 82-28,which helps to achieve a bal-ance between the high-temperature stability and the low-temperature flexibility.The increase in SBS modified asphalt con-tent leads to a decrease in the tensile strength of EA/SBS,however,the elongation at break remains above 200％.
