Bridge Substructure Concrete Deterioration
This report summarizes results of a reconnaissance survey of 45 bridges in NYSDOT Administrative Regions 1 (Albany), 4 (Rochester), 7 (Watertown), and 9 (Binghamton). They were inspected and reported by age group in 1979-80 under a previous study and discussed in Special Report 73. Visual inspections of the bridges began in the summer of 1988 and were completed in the summer of 1989. Included in this study is an analysis of mean ratings of bridge substructure elements from the Department's inventory of bridges in the same age categories. Ratings for epoxy-coated versus plain reinforcing bars in substructure concrete elements of similar age were compared. No attempt was made to determine causes of the distress observed except by inference. Problems most commonly encountered were closed cracks and spalling in splash zones, and open cracks in elements closer to the deck. Contrary to expectations based on Special Report 73, most substructure elements were found to be in good condition.
