Polymer-Impregnated Bridge Slabs - Performance Over 10 Years
The report presents the results of a study to evaluate the performance over a 10-year period of slabs that were impregnated to a depth of about 1 in with a monomer that was subsequently polymerized (shallow polymer impregnation). The slabs were used to widen a bridge. The report contains data obtained from evaluations done after 3, 5, 7, and 10 years in service. The study indicates that, based on rapid permeability tests done on cores removed from the slabs, rate of corrosion measurements made on the top mat of reinforcement in the slabs, and chloride ion content determinations done on samples removed from the slabs, shallow polymer impregnation can provide greater long-term protection against the infiltration of chloride ions and the consequent corrosion of reinforcement than conventional bridge deck concrete that is not impregnated.
