Bridge Deck Deterioration: Two Case Studies
This report deals with surface condition of three concrete bridge decks constructed in 1966 and evaluated in 1973 and 1976. These were the first bridges in New York State for which complete performance and condition data were obtained on two separate occasions. Probably the study's most significant finding was the relationship between absorption of concrete over reinforcing steel and subsequent deterioration of the surface (for spans constructed with similar materials and having similar cover depth distributions). Second, salt applications in this particular environment were estimated to be more severe than applications of salt solution on simulated decks in Federal Highway Administration studies. Conclusions are also drawn concerning the effect of concrete cover on performance, and on the effectiveness of a two-part bituminous-epoxy waterproofing membrane applied on one of the bridges.
