DEEP IMPREGNATION OF CONCRETE BRIDGE DECKS

This article details a study of deep monomer impregnation (3 to 4 in.) and in-situ polymerization of a bridge deck--using the grooving technique--to prevent corrosion. The study shows that the process is commercially feasible and the work can be successfully completed to a set of specifications by contractors with no experience with monomer impregnation and in-situ polymerization. The bridge, located on the Mt. Nittany Expressway near Boalsburg, Pennsylvania, is a three-span multigirder bridge with simply supported steel plate girders, permanent steel deck forms, and composite design. The monomer system was a mixture of 100:10:0.5 parts of methyl methacrylate, trimethylol-propane trimethacrylate (promotor and cross-linking monomer), and 2, 2-azo-bisisobutyronitrile initiator (MMA-TMPTMA-AZO).
