Laser Spectroscopy for Rapid Profiling of Steel Bridge Coating, Corrosion, and Heavy Metals

TRB’s National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) program Report 164: Laser Spectroscopy for Rapid Profiling of Steel Bridge Coating, Corrosion, and Heavy Metals has released a report that explores the development of laser-scanning technology that could provide direct measurement of the condition of bridge surfaces and undercoatings. The technology could assess the level of corrosion, if any, in the underlying steel structure.
