Abstract:

The Federal Highway Administration requires owners of structurally deficient bridges to repair, replace, restrict truck loads, or conduct analysis and testing to maintain a safe highway system. Past experiments on reinforced concrete beams showed acoustic emission (AE) testing, which “hears” the “sound” given off by the material when it is damaged, to be a highly sensitive method for detecting damage. In an effort to evaluate how AE can be used to assure safe operation of aging bridges, ODOT sponsored research into the capabilities of AE testing for cracked Reinforced Concrete Deck Girder (RCDG) bridges.
