description The rising of energy consumption and poor air quality issues have raised global attention and implementation of warm mix asphalt (WMA) technology in the asphalt industries. The constant efforts by asphalt industry to reduce emissions by lowering asphalt production temperature, made possible by incorporating warm asphalt additive named Advera®. Reclaimed asphalt pavement (RAP) and warm mix asphalt (WMA) have become the alternative materials and methods for enhancing sustainability in the asphalt industry. This study aims to determine the optimal warm mix additive and RAP through several laboratories tests. Binders blended with 0, 4, 5, 6 and 7% Advera® were evaluated using the Superpave TM rotational viscosity and dynamic shear rheometer to investigate rheological characteristics after being conditioned in a rolling thin film oven. 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. Thus, the combination of Advera® and reclaimed asphalt pavement (RAP) offer alternative way to reduce the high temperature mix, consequently slow the aging of the modified mixture without compromising its performance.
