The Materials Standards contain specifications, test methods, and provisional standards commonly used in the construction of highway facilities. The second update revises the guide’s sections on General Manufactured Materials, including: Concrete drainage structures; flexible and metallic pipe; markings and coatings; and safety devices.
The June 2019 update also contains two new standards along with 25 updated standards, AASHTO noted.
The web-based Materials Standards are available as a one-year online subscription with current subscribers automatically receiving access to all updates published during the subscription period, as well as access to recent past editions, with changes between editions highlighted for ease of reference.
