Rediset is a chemical warm mix asphalt additive that can reduce the viscosity of asphalt binder at a given temperature, hence reducing the mixing and compaction temperatures of asphalt mixes. This paper evaluates the viscosity, rutting and fatigue parameters of conventional asphalt binder blended with 0%, 1%, 2%, 3%, and 4% Rediset using the Rotational Viscometer and the Dynamic Shear Rheometer. In addition, aging factors were calculated to evaluate binder properties under unaged and short-term aged conditions. Statistical analyses of the data showed that using Rediset to decrease the viscosity of the asphalt binder at high temperatures does not adversely effects the fatigue and rutting behavior of the asphalt binder subjected to different aging conditions.
