A Shape Memory Polymer Based Self-Healing Sealant for Expansion Joint

TRB’s National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) Final Report for NCHRP-IDEA Project 142: A Shape Memory Polymer Based Self-Healing Sealant for Expansion Joint explores a sealant for use in expansion joints in pavements and bridges to help prevent adhesive and cohesive failures through a self-healing mechanism, thereby minimizing the need for replacing the sealant.
