Repairing Cracks in Portland Cement Concrete Using Polymers
Research was conducted to identify improved methods for sealing cracks in portland cement concrete bridge decks and pavements. The use of polymer concrete in pavement cracks enlarged with a crack cutter proved to be effective although the method is labor intensive. The method has been used extensively on I 610 with good results. Epoxy injection was tested in the laboratory with crack width and temperature as the variables. Good results were obtained for recracking strength and filling cracks except at low temperature. Limited field studies were performed. The use of high molecular weight methacrylate monomers proved successful in laboratory tests with cracked concrete with variable crack widths and variable moisture. Field tests were successful except when cracks were filled with debris.
