Warm mix asphalt (WMA) is prepared at lower temperatures, making it more susceptible to moisture damage. Moisture damage in asphalt mixtures can lead to stripping and is generally due to adhesion failure. An experimental investigation was carried out to evaluate the relationship between adhesive failure and direct tensile strength of asphalt mixtures. The mixtures prepared with and without WMA additive Cecabase were subjected to moisture sensitivity test and then tensile for direct tension. Image analysis technique using Environment for Visualizing Images (ENVI) Version 4.0 software was applied on the fractured surfaces of asphalt mixes that failed during the direct tensile test. The results showed that adhesion failure due to moisture damage for WMA is higher compared to those in HMA, while in PG-64 mixture the adhesion failure was higher as compared with PG-76 mixture. In addition, the direct tensile strength reduction is inversely proportional to the proportion of failure due to adhesion classified by the image analysis technique.
