Abstract:Concrete bridge decks are routinely inspected as a requirement of the National Bridge Inspection Standards. This is typically a visual inspection, with deficiencies recorded from the shoulder of the roadway, outside of traffic flow. A new 3-D optical bridge evaluation system (3DOBS) allows inspectors to capture more detailed information about the condition of bridge decks at near-highway speeds without the need for lane closures or worker exposure to traffic. Researchers trained MDOT staff on the use of the vehicle-mounted camera and image analysis software, which will supplement traditional inspections on some bridges. The additional data will help MDOT optimize the timing of deck preservation treatments to prevent costly deterioration.
