Title: APPLICATION: DEEP GROOVING--A METHOD FOR IMPREGNATING CONCRETE BRIDGE DECKS (ABRIDGMENT)
Accession Number: 00394965
Record Type: Component
Availability: Find a library where document is available Abstract: Polymer impregnation of concrete is a long-term protection method for chloride-contaminated concrete bridge decks. The deepgrooving impregnation method significantly reduces impregnation time, simplifies equipment needs, mitigates potential fire hazards, and may provide a long-lasting and more skid-resistant surface. The procedures for impregnating a concrete bridge deck using the deep-grooving method are presented. Included are methods used to calculate the optimum groove spacing, width, and depth. An optimum drying criterion using a propane-fired infrared heater is presented. A method for determining the impregnation time and polymerization times and methods for a methyl methacrylate (MMA) monomer system are also presented. In addition, methods for filling the grooves, an estimated total time to impregnate an average bridge, and cost data are presented.
