1.  ASPHALT BINDER & BITUMINOUS MIXTURES LABORATORIES (ABML):
The Asphalt Binder Laboratory studies the flow and deformation of paving materials. The laboratory's primary mission is to characterize the behavior of paving materials properly such as asphalt binder and fine aggregate mastic. Work conducted in the laboratory provides the basis for improved material specifications that enable improvement of the durability, longevity, quality, and cost-effectiveness of pavements.
The Bituminous Mixtures Laboratory specializes in the research of asphalt pavement mixtures. This laboratory supports FHWA's efforts to develop, evaluate and improve materials, mixture design technology, and performance-based tests for asphalt paving mixtures. The laboratory's activities are aimed at extending the life and improving the performance of asphalt pavement, reducing vehicle wear and tear, and shortening construction delays. The laboratory is used to assist FHWA field offices, State Highway Agencies, and the pavement community in general.

2.  PAVEMENT TESTING FACILITY (PTF):
The PTF is a specialized laboratory that enables pavement distress to be induced and measured on full-scale pavement structures. It 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.

3.  CHEMISTRY LABORATORIES:
The Chemistry Laboratory conducts fundamental research into pavement materials to provide unbiased forensic testing and to provide technical support and assistance to FHWA Division Offices, State DoTs, other Federal agencies, and other industry partners. The technology and data generated in these laboratories, as well as the expertise of the staff, are being used to enhance the durability of highway materials and to reduce operating costs.

4.  COATINGS AND CORROSION LABORATORIES (CCL):
The CCL develops and analyzes the effectiveness of innovative coatings test procedures while evaluating the durability of new coatings systems, especially environmentally compliant materials for the corrosion protection of steel bridges. The laboratory tests numerous durable coatings using both accelerated laboratory tests and natural outdoor exposure. In addition, the laboratory assists State DoTs to solve a variety of bridge coatings problems and recommends appropriate coatings for different environmental conditions.

5.  AGGREGATES & PETROGRAPHIC LABORATORIES (APL):
The APL provides facilities for the preparation and testing of aggregate samples for concrete, asphalt mixtures, and granular base course applications. The laboratory also provides petrographic sample preparation and petrographic analysis of concrete, aggregates, and other construction materials for both research and forensic studies.

6.  CONCRETE LABORATORIES (CONCLAB):
The Concrete Laboratory is used to identify and evaluate new test methods, identify and conduct concrete materials research, develop mixture design and analysis procedures for concrete pavements, and provide concrete forensics. The lab is comprised of five components including an Aggregate materials & sample preparation room, a curing room, as well as facilities for evaluating plastic concrete properties. The lab provides support for specialized testing and forensic investigations on Portland cement concrete to assist state DoTs in research and troubleshooting problems with existing pavements and structures.
