This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty randomly selected concrete bridge decks in New York State, overlaid with low-slump concrete, were studied in 1985 after an average of 5 years of service. The investigation included recording surface defects, measuring delamination and half-cell potentials, and sampling and testing for deck chloride profile. Conclusions are drawn with regard to 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.
