Galvanized Bridge Deck Reinforcing, HR-504, 1992

The deterioration of bridge decks due to steel corrosion is a problem encountered several years ago. This project, using galvanized reinforcement, began over twenty years ago. Since that time, epoxy coated reinforcement has become the specified material used in bridge decks. The decks researched in this project are located on 1-35 in Story County. They were constructed in 1967. The results from the testing done on this project show that galvanizing protects steel from corrosion due to deicing salts, resulting in less/no concrete deterioration.
