The AASHTO Materials Reference Laboratory (AMRL) is a research associate program located at the National Institute of Standards and Technology (NIST) under the sponsorship of the American Association of State Highway and Transportation Officials (AASHTO). AMRL is involved with materials used in transportation projects, including soils, aggregates, traffic and structural paints, metals, plastic pipe, asphalt binders, and bituminous materials and mixtures. AMRL, established in 1965, operates under a memorandum of agreement between AASHTO and NIST. NIST is responsible for the day-to-day management and operation of AMRL, and the AASHTO Highway Subcommittee on Materials guides the operation of the laboratory. The AMRL Council of the subcommittee maintains general oversight over the laboratory but has delegated certain responsibilities to the AMRL Administrative Task Group (ATG). This task group is responsible for conducting program reviews, making budgetary and staffing recommendations for inclusion in AASHTO's annual budget, and preparing the Association's materials standards related to the quality of laboratory testing. AMRL performs four major functions: inspection of equipment, testing procedures, and quality systems at materials-testing laboratories; distribution of proficiency samples; participation in the work of standards committees; and analysis of testing problems. This article discusses in detail AMRL's Laboratory Inspection Program and the AASHTO Accreditation Program. In conclusion it is pointed out that AMRL is taking a leadership role in facilitating the implementation of new technology, for example by including the new Strategic Highway Research Program (SHRP) test methods in its programs. Also, the laboratory's programs are being broadened in scope to be more responsive to the needs of its sponsors and the transportation industry.
