AASHTO re:source – which launched its podcast series in September 2020 – is part of the engineering and technical services division at AASHTO.
It provides services and tools through three major programs: the Laboratory Assessment Program, the Proficiency Sample Program, and the AASHTO Accreditation Program.
Developed by the AASHTO Committee on Materials and Pavements, the “Materials Standards” guide is formally known as the “Standard Specifications for Transportation Materials and Methods of Sampling and Testing and AASHTO Provisional Standards.” It contains specifications, test methods, and provisional standards commonly used in the construction of highway facilities.
AASHTO returned to a single annual release of the standards, rather than three separate annual updates, for the 2021 edition – with the PDF Download format of the guide released each year in July followed by the paperback format in September.
To make it easier for users to track updates and search for specific standards, AASHTO organized its Material Standards volumes by standard type: M and R standards in one volume; T standards in another; and MP, PP, and TP standards in the third.
On this AASHTO re:source podcast, AASHTO’s Soneira reviews the new M 339 standard – the “Standard Specification for Thermometers Used in the Testing of Construction Materials.”
