Incorporating asphalt's self-healing properties into experimental protocols can help bridge the gap between laboratory predictions and the actual field performance of asphalt mixes in terms of fatigue life. In this study, the healing potential of an unmodified binder is quantified both in the presence and absence of a warm mix additive (WMA). During the test, rest periods of varied durations (10 and 30 minutes) are introduced at 25% and 75% of damage levels prior to reaching failure to examine their influence on the further evolution of damage. It was observed that the addition of the WMA resulted in an improved healing index of the unmodified binder at different damage levels pre-failure. The findings indicate that WMA additives not only help reduce working temperatures but also improve the healing properties of bituminous mixes.
