Evaluation of HMA Mixtures Containing Sasobit

asphalt binder that is the basis for the reported stability of asphalts that contain Sasobit ®. At service temperatures, Sasobit ® modified asphalts are reported to display an increased resistance to rutting. In addition, it is reported that improved compactibility was observed with an increase in the degree of

Rheological Evaluation and Modeling of Sasobit®-Modified ...

Warm mix asphalt using Sasobit® ( Wax Company, burg, South Africa) is a new technology to reduce construction temperatures of asphalt mixes. This article presents the rheological properties of Sasobit-modified asphalt binder at high temperatures using response surface methodology. The results showed that the temperature at which the asphalt binder was blended with Sasobit had no ...

The behavior of modified asphalt binder is investigated at a wide range of temperatures ( − 6 –160°C). Results show an improvement of the asphalt binder performance at high temperatures, but adverse effects on asphalt binder performance at the low temperatures are observed. The optimum percentage of Sasobit is found to be 2% by mass of the ...
