FIELD EVALUATION OF CONCRETE POLYMERIZATION AS A BRIDGE DECK SEAL

Several monomer systems were applied to the Pit River bridge deck in an attempt to determine if a simple paint roller and squeegee application technique would be effective in producing an impermeable polymerized deck surface. Prior to monomer application, the deck surface was prepared by either steam cleaning, sand blasting or bushhammering. Polymerization was attempted by applying two monomer systems - styrene and methylmethacrylate - with various promoters and catalysts. In addition, a polyester was placed over some of the polymerizing systems to improve penetration of the underlying monomers. Permeability tests on concrete cores taken from the test areas showed that the application of monomers using paint rollers and squeegees was not a dependable method for field impregnation of monomers into concrete bridge decks.
