摘要

Critical conditions of highway bridges within the nation highlight the need for an easily deployable nondestructive tool with the ability to provide meaningful condition information for bridge inspectors and management teams. Delaminations within concrete bridge decks are one of the indicators of the deteriorating condition of the bridge, therefore accurate assessment of total area and location of these delaminations can provide invaluable information for prioritizing maintenance funding, during the decision making process. Current practices for detecting delaminations include sounding concrete with a hammer or using a chain drag. These methods require lane closure over the bridge deck and are not necessarily easy to conduct during a routine bridge inspection. In addition, past studies have demonstrated significant variations in the results from deck delamination surveys carried out by these sounding techniques.
