Abstract

The use of ground penetrating radar (GPR) to find bridge corrosion was discussed. A simple pull cart was constructed with mounts for the antennas to keep the antennas an inch above the concrete surface. A threshold level was determined to differentiate between good and corroded rebars. The variance simulations helped to determine the reflectivity of the corroded rebar.
