Waterproofing Membranes for Bridge Deck Rehabilitation
Measurements of electrical potential and resistance on 44 rehabilitated reinforced concrete bridge decks in New York State are reported. Twenty included a two-component, liquid-applied bituminous-epoxy waterproofing membrane -- New York's standard from 1958 through 1974. Ten others included a modified polyester-resin, and 14 had a variety of experimental membranes. While the bituminous-epoxy membrane system failed to perform as hoped, it has probably been no more nor less effective than membranes in general use before 1970 in other parts of the United States. Other membrane types used experimentally in New York have performed better, as a group, than the bituminous-epoxy, but not outstandingly so. None of the membranes evaluated was successful in preventing continuation of corrosion of steel reinforcement where chlorides were already present in the decks. The degree of roughness of the concrete surface on which the membranes were placed appeared to be an important factor determining their successful performance.
