|Aggregate and Petrographic Laboratory
||The Aggregate and Petrographic Laboratory (APL) provides facilities for the evaluation, preparation, and testing of aggregate sources, products, and samples for use in concrete, asphalt mixtures, and granular base course applications.
|Asphalt Binder and Mixtures Laboratory
||The Asphalt Binder and Mixtures Laboratory studies the flow and deformation of paving materials. The Laboratory's primary mission is to characterize properly the behavior of paving materials such as asphalt binder and fine aggregate mastic.
||Researchers at the Chemistry Laboratory advance the understanding of chemical changes causing road failure or damage (such as aging or deicing salts) and potential performance enhancements; help develop state-of-the-art characterization tools; and test and foster new materials development. The Laboratory validates FHWA-sponsored offsite research and assists industry and State and Government agencies with forensic analyses and unbiased support.
|Coatings and Corrosion Laboratory
||The mission of the Coatings and Corrosion Laboratory (CCL) is to develop and analyze the effectiveness of innovative coatings test procedures while evaluating the durability of new coating systems, especially environmentally compliant materials for the corrosion protection of steel bridges.
||Researchers in the Concrete Laboratory evaluate new test methods, conduct concrete materials research, develop mixture design and analysis procedures for concrete pavements, and provide concrete forensics.
||The Geotechnical Laboratory is used to study the interactions between soil and structural elements made of steel, concrete, or timber that are used for bridge foundations and retaining wall systems.
|J. Sterling Jones Hydraulics Research Laboratory
||The J. Sterling Jones Hydraulics Research Laboratory provides a means of testing the hydraulic performance of highway drainage structures and stream crossings, including the hydraulics of bridges, culverts, and storm sewers. The purpose of the Laboratory is to solve hydraulic and stream stability problems attendant to highways and to support highway engineers with design guidance and tools.
|Nondestructive Evaluation Laboratory
||The FHWA Advanced Sensing Technology (FAST) Nondestructive Evaluation (NDE) Laboratory is a world-class national laboratory and is the keystone of FHWA's research and testing efforts related to the application of nondestructive testing technologies for condition assessment of highway infrastructure.
|Pavement Testing Facility
||The Pavement Testing Facility (PTF) uses rapid pavement testing of full-scale structures to develop and verify new specifications, designs, and test procedures for rigid and flexible pavements. The facility is used by pavement and highway research engineers to evaluate the durability of both new and existing pavement materials and to help develop smoother and more cost-effective highway systems.
||The purpose of the Structures Laboratory is to support FHWA's strategic focus on improving mobility through analytical and experimental studies to determine the behavior of bridge systems under typical and extreme loading conditions. These experimental studies may also include tests of bridge systems developed to enhance bridge durability and constructability over time. Data from these studies help upgrade national bridge design specifications and improve the safety, reliability, and cost effectiveness of bridge construction in the United States.
