Survey of Concrete Deterioration in Bridge Substructures
The condition of bridge substructure elements in New York State was examined through a reconnaissance survey of 45 bridges in Regions 1(Albany), 4 (Rochester), 7 (Watertown), and 9 (Binghamton), and an analysis of condition ratings of specific substructure elements obtained from the Department's computer-stored inventory. Concrete from substructure beams and columns was sampled and tested to confirm the principal causes of deterioration. The condition of most substructure members was found to be satisfactory and they are expected to provide long service lives. Some problems were observed with pier cap beams and pier columns in the 11- to 15-year age group in Regions 4 and 5, and are expected to deteriorate with time. Open cracking and spalling were the principal types of defects affecting columns and beams, and were found to be due to corrosion of embedded steel.
