Abstract

To understand the viscoelastic performance of sulfur-modified asphalt mixture, the penetration test and dynamic modulus test are used to analyze binder and mixture performance with different sulfur content. These test results show that lower sulfur concentration in the binder will increase asphalt mixture’s viscosity and temperature sensitivity. But higher sulfur concentration in the binder will increase asphalt mixture’s elasticity and reduce temperature sensitivity.

Keywords:
road engineering, sulfur-modified asphalt mixture, dynamic modulus, temperature sensitivity, viscoelastic performance
