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. 收起
