Through laboratory performance tests, this study evaluated the mixtures{u2019} moisture sensitivity, permanent deformation, resistance to fatigue, resilient modulus and durability of the reclaimed asphalt pavement (RAP) in warm mix asphalt. Hot mix asphalt (HMA) and warm mix asphalt (WMA) included in the experiment were designed using different RAP mixture proportions (0, 20, 40, and 60 per cent) in comparison with HMA. RedisetTM additive, AdveraTM additive, and HoneywellTM additive to the asphalt were the main components of concoction for the WMA mixtures produced in this study. The Superpave design method was used to design HMA, WMA, and WMA mixed with the RAP. Types of laboratory performance tests conducted throughout the study were the moisture sensitivity test, the permanent deformation test, the fatigue resistance test, resilient modulus test and the Cantabro loss test. Results indicated that all the WMA mixtures had a significantly improved tensile strength ratio (TSR) compared to the HMA mixtures. However, varying the proportion of the RAP incorporated into the RAP mixtures revealed no significant improvement in TSR. The HoneywellTM additive could improve the rutting resistance of WMA mixtures as well as increase the mixtures{u2019} resistance to fatigue, compared to the conventional HMA. This was because the mixture with added HoneywellTM additive had a greater number of cycles to fatigue failure. By adding a higher percentage of RAP into WMA with AdveraTM additive (40-60 per cent RAP), the mixture{u2019}s resistance to fatigue was significantly improved. The greater RAP content can improve the resilient modulus of asphalt mixtures. All additives improved the durability of the mixtures. Adding a higher percentage of RAP, however, resulted in greater loss of mass.
