A LEVEL PLAYING FIELD

As quality control/quality assurance programs are implemented nationwide and the field enters the Superpave era, hot mix asphalt (HMA) producers and labs are seeking accreditation from the American Association of State Highway and Transportation Officials (AASHTO) to ensure the credibility of their procedures. AASHTO established its accreditation program in June 1988. Gaining AASHTO accreditation involves an inspection by officials of the AASHTO Materials Reference Laboratory. The program formally recognizes the competency of testing laboratories to perform specific tests on asphalt cement, cutback asphalt, emulsified asphalt, soil, aggregate, HMA, hydraulic cement, and portland cement concrete. By a regulation issued in 1995, the Federal Highway Administration (FHWA) required the central laboratories of all state transportation departments to be AASHTO-accredited by June 1997 for at least basic pavement materials testing. FHWA regulations also require that by June 29, 2000, states set up qualification programs for laboratories used in the acceptance decision of federally funded highway projects.
