A major challenge associated with overlays is the reflection of the cracks from the underlying pavement due to the combined effect of traffic and environmental conditions. In 2006 NDOT initiated a three-phase study to mitigate reflective cracking that resulted in the development of an engineered stress relief course (ESRC) with performance-based mix design specifications to be used as an interlayer between the existing AC layer and the AC overlay.

This research aims to evaluate the laboratory and field performance of the ESRC in the demonstration projects. Moreover, it aims to determine the necessary information to predict the long-term performance of the ESRC. The constructability of the ESRC was closely monitored, and extensive laboratory evaluation was conducted to assess the ESRC stability and resistance to cracking.
