Pilot projects with two midwestern state’s Departments of Transportation analyze the structural integrity of more than 200 bridges using thermal infrared imaging to identify structural concrete anomalies
NV5 Geospatial, North America’s most comprehensive geospatial data firm, announced ahead of the 103rd Transportation Research Board (TRB) Annual Meeting that NV5 Geospatial’s thermal infrared (TIR) Solutions for transportation infrastructure challenges are being implemented in transportation projects analyzing concrete bridges in the Midwest. This remote sensing technology offering enables local, regional and governmental transportation agencies to identify structural problems well before they reach the surface of concrete bridge decks.
This groundbreaking work comes at a time when 42% of U.S. bridges are over 50 years old and more than 46,000 of them are considered “structurally deficient” according to the American Society of Civil Engineers (ASCE) “2021 Report Card on Infrastructure.” The ASCE report also found that “178 million trips are taken across these structurally deficient bridges every day,” potentially endangering countless lives. The U.S. was ranked by the World Economic Forum 13th globally when it comes to the overall quality of infrastructure.
Concrete bridge decks are critical components of the structure that require periodic inspections for continuous maintenance, rehabilitation, and replacement work. TIR is integral to non-destructive inspection (NDI) techniques for analyzing concrete bridge decks and identifying potential delamination made quicker and more efficiently by aerial collection.
