ATREL Earns AASHTO Accreditation

The Advanced Transportation Research and Engineering Laboratory (ATREL), headquarters of the Illinois Center for Transportation, was recently accredited by the American Association of State Highway and Transportation Officials (AASHTO). This accreditation means that ATREL has demonstrated proficiency for the testing of construction materials. ATREL is accredited in the categories of Quality Systems, Hot Mix Asphalt, and Aggregate.

The AASHTO Accreditation Program (AAP) was established in 1988 as a means of formally recognizing the competence of testing laboratories to perform specific tests on construction materials. AAP is a voluntary program that is available to all testing laboratories including government, commercial, university, and research facilities. There are nearly 1,500 individual laboratories that are currently accredited through AAP, making it the largest accrediting body of construction materials testing laboratories. AAP utilizes laboratory assessment and proficiency sample services provided by the AASHTO Materials Reference Laboratory (AMRL) and the Cement and Concrete Reference Laboratory (CCRL). AMRL provides administrative coordination and technical support for AAP.
