Determining the Depth of Hydro Demolition using Lidar Methods

Missouri University of Science and Technology was contracted to conduct research on the effectiveness of using ground-penetrating radar (GPR) to assess several highway bridges in rural Missouri. The assessment was to be based on the principle that sound concrete has a different density than unsound concrete, and this property could be used to map areas of bridge decks requiring repair.While the GPR assessment involved a dozen bridges, three bridges were selected to provide ground-truth data to calibrate the GPR-based assessment process.
