Abstract:

The Ohio Department of Transportation requested from ORITE to conduct GPR runs to ascertain the thickness of cover above the top rebar layer of Woody County bridge WOO-75-1294 on interstate 75 over U.S. route 6. The main purpose of these surveys was to see if there was enough cover on top of the rebar to allow grinding of the concrete surface. Surveys and data collection were conducted on the bridge on April 20, 2016. A ground penetrating radar system was used to collect data on the I-75 Bridge over SR 6 to ascertain the depth of rebar at specific locations. A calibration run was conducted and the depth to rebar was manually checked at that location to calibrate the propagation velocity of the GPR antennas. Systematic data was collected at 2 foot increments, and then the data was processed to show an overall depth to cover of the top rebar, and specific graph for locations of interest were also generated.
