Fifty randomly selected concrete bridge decks in New York State, overlaid with low-slump concrete, were studied in 1985 after 5 years of service. The study included recording surface defects, measuring delamination and half-cell potentials, and sampling and testing for deck chloride profile. Conclusions are drawn about the nature and significance of the observed damage, and estimates are made of service life expectancy. Policy implications for the New York State Department of Transportation are discussed.
