SPR-4839: Evaluation of Utilizing 3D GPR for Quality Assurance of Bridge Deck Rebar Cover and Delamination Screening

The main objective is to verify that INDOT’s 3D GPR system will provide rebar cover thickness estimates that are accurate and precise enough to be utilized for quality assurance (QA) of rebar cover thickness for newly constructed bridge decks. The research will also examine utilizing the 3D GPR for delamination screening.
