AASHTO re:source – which launched this podcast series in September 2020 – is part of the engineering and technical services division of the American Association of State Highway and Transportation Officials.
It provides services and tools through three major programs: the aforementioned PSP service, its Laboratory Assessment Program, and the AASHTO Accreditation Program.
The new aggregate gradation and gravity sampling portion of the PSP service has been three years in the making, according to AASHTO re:source, and is designed to both streamline and reduce the cost of the group’s PSP service.
