VERMONT EVALUATES BRIDGE DECK MEMBRANES

From 1971 through 1982 Vermont's Agency of Transportation conducted a field evaluation of 33 membrane systems to seal concrete bridge decks from corrosive de-icing salts. Based on analysis of over 1,600 core samples, the results show that the experimental waterproofing systems outperformed Vermont's standard treatment of tar emulsion. The best performance was with preformed sheet membranes and thermoplastic systems, followed by polyurethane, epoxy, and tar emulsion. Six exposed bridge decks were also monitored for chloride contamination as a control. The overall performance of five vulcanized, cured or cross-linked elastomer systems selected by NCHRP was good, but application was difficult, thus making it apear doubtful that the systems could be properly placed under typical field conditions. Long-term results indicate a variety of membrane systems can be made to work if adequate time and effort is spent in selection, design and installation.
