About the research

As the highway system ages throughout the United States, there is an increasing occurrence of joint associated distress in concrete pavements. This distress can be a result of several factors, including reactive materials, fatigue from vehicle loadings, misaligned dowel bars, poorly drained joint systems, as well as attack from aggressive deicing chemicals. Since the distress occurs primarily near the joints, while the remainder of the slabs are still in serviceable condition, it is often more economical and sustainable to perform joint repairs.

The objective of this project is to produce a short technical brief and webinar containing the best practices for the repair of distressed joints in concrete pavements and overlays, particularly those used in NRRA member states. The techical brief will include causes for the distresses, as well as case histories of successful and non-successful repair methods. A one-hour long webinar will also be developed, delivered, and recorded for future reference.
