For decades, nondestructive evaluation (NDE) has been an essential part of the extraordinary quality and performance achieved in modern steel bridges. Steel bridges have evolved with the use of new materials and fabrication practices, but the NDE methodologies deployed have generally remained the same. The goal of this umbrella topic is to capitalize on the many opportunities to improve fabrication practices with new and improved NDE for measurement and inspection.
Two NDE Roadmap working groups were established in March 2020 under the auspices of the Transportation Research Board (TRB) Standing Committee on Fabrication and Inspection of Metal Structures (AKC70) and the Standing Committee on Testing and...
