Book excerpt: This report compares the field performance of two reinforced-concrete bridge deck sections designed using the American Association of State Highway and Transportation Officials (AASHTO) specifications and the Ontario Highway Bridge Design Code (OHBDC) isotropic reinforcement method. For direct comparison of their field performance under similar conditions, the two bridge deck sections were incorporated into the same bridge. The two-lane, five-span bridge, called the Ferry Hill Bridge, is located in Orono, Maine. It is 450 ft long and 46 ft, 8 in. wide and consists of longitudinal steel girders with a monolithic 8-in.-thick reinforced-concrete deck. The field performance of the two deck sections was evaluated over a seven-year period by measuring rebar strains at 28 locations in the deck and conducting visual inspections of the underside of the concrete deck.
