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
Read MoreWarm 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 ...
Read MorePMA binders. In particular, the use of Sasobit® showed the enhanced rutting resistance properties at high pavement temperature and more elastic properties at lower temperatures. Keywords: PMA binders, WMA, rheology. 1 Introduction Warm mix asphalt (WMA) technologies are progressing very rapidly,
Read MoreSasobit is one of the organic additives of warm mix asphalt. It is used as a binder modifier to produce rut resistant mixtures. It provides the option of reducing fume emissions, saving energy and ...

Read MoreThe microstructure–property relationship of Sasobit modified Warm Mix Asphalts (WMA) is investigated in terms of thermal, rheological and morphological studies. Four asphalt binders with different types and grades and two Sasobit concentrations (1% and 3% by weight) are included in this study.
Read MoreThe 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 ...
Read MorePresent study evaluated the rheological properties of polymer- and crumb rubber-modified bitumen with various doses of WMA additive Sasobit (1%, 2%, and 3% by binder weight). Frequency sweep and temperature sweep results showed that increase in Sasobit content improved elastic properties of binders.
