Abstract:Today’s environment is increasingly hostile to bridge decks with exposure to deicing salts and environmental factors such as large temperature swings and polluting chemicals. Being subjected to the most severe loading of all the bridge components, decks undergo deterioration and cracking, which usually results in the deck service life being shorter than that of the other major bridge components. Overlays can replace the deteriorated part of the deck, thus extending the bridge life. Many states including Iowa have been using overlays to replace the damaged deck concrete.
