Use of warm mix asphalt (WMA) in pavement industries has been growing rapidly over last decade because it can lower down the construction temperature and subsequently reduces the environment pollution and energy consumption. + WMA sample showed significant enhancement in rutting resistance due to presence of polymer. In addition to mixture test, extracted binders from these mixtures were also evaluated though Superpave performance grade (PG) and multiple stress creep recovery tests. The performance orders of the extracted binders from these two tests are also similar as the mixture performance. This study also found that non-recoverable compliance (Jnr) value obtained from the MSCR test demonstrated better correlation with HWTT (R 2 = 0.96) compared to Superpave rutting parameter (R 2 = 0.68).
