Results of polymer impregnation of concrete slabs and a bridge deck to a depth of 4 in. (100 mm) are presented and examined. The criteria developed for drying the slabs and bridge decks to a depth of 4 in. (100 mm) using gas-fired infrared heaters (applied on one surface only) is either to measure the temperature at 4 in. (100 mm) and cease applying heat when it reaches greater than or equal to 230 deg F (110 deg C) or stop applying heat when the rate of temperature rise on the surface is less than 10 deg F/hr. (6 deg C/hr). Impregnation by ponding of the monomer system (100 parts methyl methacrylate, 10 parts trimethylolpropane trimethacrylate, and 0.5 parts azobisisobutyrl nitrile) to achieve a depth of 4 in. (100 mm) requred 4 days or longer. Polymerization of the monomer system in the concrete can be achieved at 4 in. (100 mm) by using a hot water bath and by maintaining a temperature at 4 in. (100 mm) of greater than or equal to 130 deg F (55 deg C). /ASCE/
