Nondestructive Evaluation of Bridge Decks with SounDAR

From June 12 through October 14, 2019, BDI performed an extensive nondestructive evaluation (NDE) of 67 bridge decks utilizing the Deck Acoustic Response (DAR) testing methodology with BDI’s SounDAR testing system.

SounDAR measures the acoustics of the deck in response to a known dynamic excitation. The results identified the subsequent areas of deteriorated concrete and map the locations in varying stages of degradation. The results are similar to those measured with traditional sounding methods such as hammer sounding, chain drag, or static impact echo (IE).
