VERMONT'S EXPERIENCE WITH BRIDGE DECK PROTECTIVE SYSTEMS

Intrusion of moisture and deicing chemicals into reinforced concrete bridge decks results in premature deterioration of the concrete and corrosion of the reinforcing steel. Vermont's search for an effective waterproofing system which would seal bridge decks and thus prevent intrusion of the moisture and chlorides has resulted in the application and evaluation of 29 different membrane systems since 1971. The results suggest that simple and inexpensive materials could be specified for sealing the major portion of a deck surface if a compatible and impervious membrane material is placed over poorly drained areas. The results of laboratory tests indicate that liquid-applied membranes offer substantial protection, even when pinholes and bubbles occur in the coatings, when contrasted with the chloride intrustion which occurs in untreated concrete.
