Rheological Evaluation and Modeling of Sasobit®-Modified Asphalt Binder at High Temperatures

摘要: Warm mix asphalt using Sasobit® (Sasol Wax Company, Sasolburg, South Africa) is a new technology to reduce construction temperatures of mixes. This article presents the rheological properties Sasobit-modified binder at high response surface methodology. The results showed that temperature which was blended with Sasobit had no effect on high-temperature binder, including viscosity and viscosity–temperature susceptibility, each aging state. All empirical models follow second-order polynomial trends test temperature, contents, their interactions condition.
