Summary
This document serves as an informational overview of the Federal Highway Administration’s (FHWA) Turner-Fairbank Highway Research Center (TFHRC), identifying it as the premier facility for infrastructure, operations, and safety highway research. The text outlines the center’s mission to advance transportation innovations that ensure a safer, equitable, and efficient national highway system. It details the capabilities of the 15 state-of-the-art laboratories housed within the facility, which collectively address pressing transportation issues through objective technical expertise and research leadership. The TFHRC employs a multidisciplinary approach, utilizing professionals such as civil, mechanical, and biomedical engineers, chemists, psychologists, and economists. The laboratories are categorized by specific research domains. Materials science is addressed through the Aggregate and Petrographic Laboratory, which evaluates roadway construction materials for durability; the Chemistry Laboratory, which investigates chemical causes of road failure; the Concrete Laboratory, focused on mixture design and sustainability; and the Asphalt Binder and Mixtures Laboratory, which characterizes paving material properties like strength and ductility. Structural integrity and preservation are managed by the Coatings and Corrosion Laboratory, which develops protective coatings, and the Structures Laboratory, which studies bridge system behavior to improve safety and reliability for the nation’s approximately 600,000 bridges. Operational and environmental challenges are tackled by several specialized facilities. The Geotechnical Laboratory studies soil-material interactions in foundations, while the J. Sterling Jones Hydraulics Research Laboratory investigates drainage performance and bridge scour using physical experiments and modeling. The Nondestructive Evaluation (NDE) Laboratory identifies weaknesses in existing infrastructure without compromising structural integrity. Safety and human factors are central to the Federal Outdoor Impact Laboratory (FOIL), which stages high-speed collisions to validate computer models, and the Human Factors Laboratory, which uses virtual reality and fieldwork to optimize the experience of drivers, pedestrians, and bicyclists. The Geometric Design Laboratory develops tools like the Highway Safety Manual, and the Pavement Testing Facility simulates long-term road use to assess material durability. The significance of TFHRC lies in its role as a hub for translating research into practical applications. The Saxton Transportation Operations Laboratory (STOL) serves as a testbed for new technologies, including connected vehicles and traffic networks, before large-scale deployment. The Safety Training Analysis Center (STAC) disseminates decades of safety research to state transportation departments. By integrating these diverse capabilities, TFHRC aims to enhance the quality of life for Americans by improving the reliability, safety, and efficiency of the highway system through continuous innovation and collaboration with academia, industry, and government agencies.
