RHEOLOGICAL AND MECHANICAL PROPERTIES OF BLENDED ASPHALTS CONTAINING RECYCLED ASPHALT PAVEMENT BINDERS

This paper presents experimental investigation on rheological and mechanical properties of asphalt binder containing recycled asphalt pavement (RAP). It also includes evaluation of resistance characteristics against permanent deformation, fatigue and low temperature cracking. A good linear relationship between log-log rheological properties and the amount of RAP binders was obtained from this study. It was found that the addition of RAP binder generally increases the resistance against permanent deformation. The dynamic flow stress was found to increase with RAP: binder content much like the variation in compressive strength under quasi-static conditions. The dynamic flow stress was not affected by the amount of RAP binder at low temperature.
