The overall performance and longevity of highway bridges is highly dependent upon the integrity of their deck joints. The North Carolina Department of Transportation has experienced problems with bonding in the armored deck joints installed on many of its bridges. These defects have historically been detected using conventional NDT techniques such as visual inspection, chain-dragging and by detecting sounds made by the joint due to passing traffic. By the time these methods are effective the joint has usually failed, however, and must be replaced.
