A study of deterioration in concrete bridge decks
Seven phases of study related to the problem of bridge deck deterioration are reported. The variables include timing variations for completion of hauling and finishing deck concrete, concrete test variations, and weather variations; an increase in depth of cover over the top reinforcing steel from 1 1/2 to 2 inches; insulating the underside of a bridge deck; sealing different areas of a bridge deck with one and five applications of linseed oil and with one application of a penetrating epoxy sealer; using an admixture in bridge deck concrete; evaluation of various field applied waterproofing membranes for effectiveness in protecting bridge decks (some of these membranes are no longer available); and determining chloride content of concrete from bridge decks with asphaltic concrete overlays with and without protective membrane systems.
