Paper Title:
Effect of Rejuvenators on Performance of Recycled Hot Mix Asphalt Mixtures
  Abstract

Effects of different viscosity rejuvenators on performance of recycled hot mix asphalt (RHMA) mixture were investigated by testing of water stability, fatigue property and rutting resistance. The results indicate that rejuvenator with low viscosity shows more significant influence on the enhancement of fatigue property at high stress ratio and water stability of RHMA mixture than rejuvenator with high viscosity due to its better diffusion ability into aged bitumen. The water stability and fatigue property of RHMA mixture with 15 wt% low viscosity rejuvenator can be close to virgin hot mix asphalt mixture. Compared with rejuvenators of medium and high viscosity, the rutting resistance of RHMA mixture is reduced more obviously by rejuvenator with low viscosity, but still meets the application requirements of RHMA mixture.
