Rheological and Fatigue Properties of Asphalt Binders Containing Anti-Rut Agents
Modification of asphalt binders has increasingly become the norm in designing optimally performing pavement. In this paper, an anti-rut agent was used as a modifier to add into base asphalt and its effects on the property of the asphalt were investigated. A shear blender was used to ensure a good distribution of the anti-rut agent. The conventional physical properties test and Dynamic Shear Rheometer (DSR) test were used to evaluate the properties of the asphalt. The results showed that the softening point and rutting parameter increases significantly, the ductility and penetration decrease due to the introduction of the anti-rut agent. Besides, the result of fatigue test showed that excess anti-rut agent may lead a deterioration in the fatigue life. Key word: Anti-rut agent; Rutting parameter; Rheological property; Fatigue life.
