A Study of Deterioration in Concrete Bridge Decks
The study includes (1) a detailed survey of deterioration on 620 bridge decks throughout Missouri, (2) observation of construction procedures and testing of fresh concrete on bridge decks, (3) analysis of cores taken from sound and deteriorated areas of bridge decks. The major findings from this study were: (1) fracture plane and surface mortar deterioration are the most serious types of bridge deck deterioration in Missouri; (2) fracture plane is associated with (a) a built-in plane of weakness occurring in the plane of the top mat of reinforcing steel, (b) use of de-icing salts, (c) surface cracking, and (d) depth of cover over the top steel; (3) surface mortar deterioration is associated with an excessive amount of mixing water, an insufficient amount of entrained air, the use of de-icing salt, and the severity of the frost action.
