Bridge Deck Sealer Monitor: Thermal Sealcheck

The use of sealers to prevent corrosion damage and extend the life of bridge decks is increasingly implemented as a bridge preservation tool to help ensure the state of good repair for bridge decks.

The TRB Highway Innovations Deserving Exploratory Analysis (IDEA) Program's Bridge Deck Sealer Monitor: Thermal Sealcheck presents a new nondestructive technology to evaluate the effectiveness of sealers applied to concrete bridge decks. The concept uses time-lapse thermography to measure water absorption/evaporation characteristics on a bridge deck in order to assess the effectiveness of concrete sealer.
