This techbrief highlights the research conducted to investigate the current use of nondestructive evaluation (NDE) data to assess the condition of bridge and tunnel elements. However, based on interviews with personnel in Lead Adopter States and after consultation with engineers at FHWA, the research team focused on bridges and bridge decks.
This technote explores the use of PL for culvert inspections. This project was carried out in collaboration with the Utah Local Technology Assistance Program (LTAP) and the Utah Department of Transportation (UDOT). This case study supported an extensive research project underway by Utah LTAP evaluating a variety of technologies to obtain metrics fo
