Determining Bridge Deck Chloride Quantities Using Ground Penetrating Radar

Monday, July 13, 2020 - 13:30

Chloride infiltration into concrete is the major cause of corrosion induced delamination in steel reinforced bridge decks and repairing delaminated concrete is a major cost factor in bridge deck rehabilitation.

The TRB Highway Innovations Deserving Exploratory Analysis Program's Determining Bridge Deck Chloride Quantities Using Ground Penetrating Radar is an investigation of an entirely new method for determining chloride quantity in bridge decks using nondestructive GPR technology in combination with a limited number of cores for calibration.
