The American Association of State Highway and Transportation Officials recently issued a new publications catalog. The new index – entitled AASHTO Publications Catalog-2021, Volume 4 – includes the latest information concerning the organization’s publications, including descriptions, available formats, and prices.

AASHTO also noted that the paperback version of its Standard Specifications for Transportation Materials and Methods of Sampling and Testing and AASHTO Provisional Standards, commonly referred to as the “Materials Standards” guide, is now available.

Developed by the AASHTO Committee on Materials and Pavements, the Materials Standards guide contains specifications, test methods, and provisional standards commonly used in the construction of highway facilities.
