Polymer impregnation of concrete can be used for the long-term protection of salt-contaminated concrete bridge decks. However, the current impregnation process requires long impregnation times and the development of new equipment. In addition, most monomers are a potential fire hazard. A laboratory investigation was performed to develop a simplified system that will reduce the impregnation time, simplify the equipment needs, and mitigate the potential fire hazards by deep grooving the concrete. The monomer used was an MMA-TMPTMA-AZO system. The laboratory results indicate that the impregnation time can be significantly reduced by optimizing the groove width, depth, and spacing. Optimum drying (by using infrared heaters) and polymerization conditions for the grooving conditions are also presented. The results of the laboratory study demonstrate the feasibility of the method and the need for a full-scale field trial to demonstrate its applicability to field conditions.
