This study explored the potential of using high reclaimed asphalt pavement (RAP) content with hot mix asphalt (HMA) in base and surface courses. A total of four Superpave mixes containing different percentages of RAP namely, 25% RAP and 40% RAP for S3 base courses and 0% RAP and 10% RAP for S4 surface courses were designed, constructed and tested. The mechanistic characteristics of mixes were evaluated by conducting creep compliance, dynamic modulus, Hamburg rut, and 4-point beam fatigue tests. The creep compliance results showed reduction in compliance of the mix due to increase in the RAP content. The dynamic modulus test results illustrated that the asphalt mix containing a higher amount of RAP has higher dynamic modulus values. The increase in RAP content reduced rutting susceptibility and improved moisture damage potential of both S3 and S4 mixes.
