A nondestructive inspection of 52 bridge decks was conducted  in central New York State utilizing Ground Penetrating Radar (GPR). The objectives of the GPR inspection were to provide an up‐to‐date assessment of the physical condition of the concrete deck, including the overall quantity of deteriorated concrete within the bridge and on a span by span basis. The GPR bridge deck inspection was performed at highway speeds, without the need for traffic control. The nondestructive inspection  was conducted for the New York State Department of Transportation.

A sample deterioration map of we provided from the inspection are shown below.
