In this respect, conventional asphalt binder grade PG64 was used as the base binder. Performance of modified samples incorporating 10, 20, 30 and 40% RAP of total mass were evaluated for resilient modulus, rutting and moisture susceptibility. The results show that Advera®. modified binder significantly reduced mixing and compaction temperatures. Modified binder with 5% Advera® show significant increase in rutting resistance for both unaged and short term aged compared to virgin binder. The microstructure of Advera® modified asphalt binder also changed significantly compared to the control asphalt. The morphological evaluation shows that Advera® modifier was completely blended with the binder. The performance of 40% RAP modified WMA mixtures produced at 30oC lower than conventional HMA show increases 20-35% on performance in term of resilient modulus (MR), rutting and moisture susceptibility. Statistical analysis on correlation between rheological Advera® modifed binder and performance of RAP modified WMA mixture proved that there is a strong correlation exists between viscosity and rutting properties.
