EFFECTS OF DEICER SALTS AND ROADWAY CONTAMINANTS ON POLYMER IMPREGNATION OF BRIDGE DECK CONCRETE

Cores, 4in. (10 cm) wide, extracted from three 7-year-old concrete bridge decks were inpregnated with methyl methacrylate to evaluate the effects of deicer salts and roadway contamination on polymer impregnation. All specimens were impregnated by soaking from the top (traffic) surface at atmospheric pressure for a sufficient period of time to achieve approximately 5 in. (12.7 cm) of penetration. Deicer salts, in the quantities measured in the three bridge decks, did not reduce the depth of polymer penetration or the volume of voids filled with polymer. However, the rate of penetration decreased as salt concentration increased. The rate of penetration was a linear function of the square root of time. Removal of roadway contaminats by lye, detergent, or sandblasting had no apparent effect on the rate or extent of polymer impregnation.
