AASHTO re:source, formerly AMRL, operates in civil engineering as a center dedicated to advancing quality and excellence in construction materials testing. It offers services through three core programs—Laboratory Assessment Program (LAP), Proficiency Sample Program (PSP), and the AASHTO Accreditation Program (AAP)—to evaluate testing competency, support continual improvement, and foster confidence among laboratories and the specifiers who rely on them. As part of AASHTO's Engineering and Technical Services division, the organization sits within a framework that sets technical standards for highway system development. Headquartered in Frederick, Maryland, the organization is a small to mid-sized operation serving laboratories and transportation stakeholders who rely on standardized testing practices. It is linked to AASHTO, an association representing all fifty states, Washington, D.C., and Puerto Rico, which serves as a liaison between state departments of transportation and the federal government to promote an integrated national transportation system. A notable recent development is the July 2022 digital release of the 42nd edition of the Standard Specifications for Transportation Materials and Methods of Sampling and Testing, along with AASHTO Provisional Standards.
