BRIDGE DECK INSPECTIONS GO FASTER USING INFRARED THERMOGRAPHY

The article discusses a bridge deck inspection project conducted by the City Street Department in Cedar Rapids, Iowa. The application of thermographic inspection techniques is credited with reducing inspection time for the six bridges involved from a possible two months to two days. The project entailed an infrared inspection of each bridge deck to identify areas of delamination in the concrete deck. An infrared camera is capable of locating areas of delamination in the deck due to the temperature differential established between sound concrete and delaminated concrete, under certain environmental conditions. A conventional video inspection of the top surface of the deck was completed in conjunction with the infrared inspection to record the condition of the deck. To confirm and document the accuracy of the infrared inspections, pavement cores were subsequently taken out of each bridge deck.
