Long-Term Rehabilitation of Salt-Contaminated Bridge Decks

J. A. Manson / R. G. Slutter / J. W. Vanderhoff / R. E. Wyers / P. D. Cady

This report describes results of a critical review and research on possible new methods for the rehabilitation of salt-contaminated bridge decks. Emphasis was given to impregnation with poly(methyl methacrylate) and to the concept of scarification followed by impregnation with a polymer or corrosion inhibitor and overlaying with a low-permeability cover. Tests for resistance to freezing and thawing and for polarization resistance (a measure of corrosion resistance) were made on various combinations of substrate treatment and overlay. A new method to facilitate impregnation was demonstrated; the method involves deep grooving of the concrete prior to impregnation.
