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. AMRL and the Cement and
Concrete Reference Laboratory (CCRL), which is sponsored
by the American Society for Testing and Materials, make
up the Construction Materials Reference Laboratories at
the NIST Building and Fire Research Laboratory. The
primary mission of these two programs is to improve the
quality of testing in laboratories that test
construction materials. 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. CCRL conducts programs for cements,
concrete, aggregates, pozzolans, and reinforcing steel.
Both laboratories are outstanding examples of how
federal and state governments and the private sector can
cooperate to meet a common goal; improving the quality
of constrcution in the United States.
