This report reflects the results of a comprehensive research program in response to the problem of bridge deck deterioration. This program placed emphasis on protecting newer decks as well as repairing damaged ones. Two basic approaches were applied to protecting bridge decks: (1) Prevent the penetration of chloride ions to the rebars by using special concrete overlays, deck sealers and waterproof membranes. (2) Use galvanized or epoxy coated rebars to protect the steel after chloride ions have contaminated the surrounding concrete. Bridge decks were constructed or repaired using the systems mentioned above. The decks covered by this study were built or repaired from 1974 to 1978 and were tested annually through 1981. Testing consisted of visual observations, electrical potential corrosion measurements, measuring depth of concrete cover over rebars, delamination detection and determining chloride ion content.
