DEPTH OF CONCRETE COVER OVER BRIDGE DECK REINFORCEMENT

Fifty concrete bridge deck spans in New York State were surveyed with a pachometer for depth of clear concrete cover. Compliance with a design requirement for a minimum of 2 in. (51 mm) occurred at 77.3 percent of the locations measured. Spans having a high degree of compliance also tended to have relatively uniform cover depths. The degree of compliance appeared to be related to construction practices. The distribution of cover depths on individual spans was generally not normal, and a construction tolerance of plus or minus 1/2 in. (plus or minus 13 mm) was determined to be reasonable for the type of requirement under which the decks were built.
