    Abstract

    Premature failure of portland cement concrete bridge decks is of national concern, particularly in those areas where chloride residues accumulate in the concrete from winter deicing operations. West Virginia's research and field usage indicates that the application of a relatively thin (1 to 2-in.) overlay of portland cement concrete or mortar containing a latex modifier may result in a significant increase in the useful life of bridge decks. Eighteen structures, including both new construction and renovation of existing decks, have received the latex-modified concrete overlay. Results to date have been most encouraging.
