    This thesis documents the findings of a laboratory research study that was conducted to evaluate four Warm Mix Asphalt (WMA) technologies, namely Evotherm M1, Kaoamin 14, Sasobit, and Rediset. The asphalt binder was evaluated after being modified with each of these additives and the results indicated that the additives reduced the viscosity. The mixture with the modified asphalt binder was evaluated for Compactability, moisture susceptibility and permanent deformation susceptibility. The compactability results for all the modified mixtures showed that the specimens were not susceptible to temperature after being compacted at a temperature range between 240 °F and 285 °F. The moisture susceptibility results showed that every mixture is not susceptible to moisture, therefore, the mixture with the additive Evotherm M1 has less stripping probability from the aggregate due to the Tensile Strength Ratio (TSR) of 96.1 % that was obtained. The Flow Number (FN) test showed that the compacted mixtures subjected to a traffic level between 10 and 30 Million Equivalent Single Axle Loads (MESAL) are not susceptible to permanent deformation proving that the reduction of temperatures will not affect the asphalt pavement performance compared to Hot Mix Asphalt (HMA).
