Popis:	A ground-coupled ground penetrating radar (GPR) system was used to assess the condition of two reinforced concrete bridge decks. After each GPR assessment was completed, the bridge deck was rehabilitated using a hydrodemolition process to remove deteriorated concrete from upper surface of the deck. LiDAR technology was used to create maps depicting the deck surface before and after the concrete removal. The objective of this work was to corroborate the GPR condition assessments by comparing the spatial distribution of the GPR and LiDAR mappings. This work illustrates that GPR data have the potential to predict concrete repair estimates.
