AASHTO re:source – a division of the American Association of State Highway and Transportation Officials – provides services and tools through three major programs: the Laboratory Assessment Program, the PSP, and the AASHTO Accreditation Program. It also launched this podcast series in September 2020.

Proficiency sampling serves as a valuable tool for evaluating laboratory performance and competency – laboratories that are key to ensuring the material used to build highways, streets, and roads is uniform and of high-quality. This particular podcast looks at some of the AASHTO re:source’s findings from its most recent batch of soil classification samplings taken during the month of May.
