Delamination is probably the most serious form of deterioration that is commonly found in bridge decks. It ultimately results in large-scale spalling that necessitates costly repairs. This type of failure is believed to be caused chiefly from salt-induced corrosion of the reinforceing steel. An instrument designed to detect delamination and the validation tests are described. The instrument has been used by Texas Highway Department maintenance personnel and has been found to be an effective and practical tool, especially on resurfaced decks. Other bridge deck evaluation techniques that were investigated are delamination detection, corrosion potential, acoustic velocity, Windsor probe, Schmidt Rebound Hammer, and direct tensile strength. It appears that all of these techniques have considerable merit. It is believed that any of them can be used to search out weak spots or deterioration in bridge decks.
