The American Association of State Highway and Transportation Officials released the first of three 2019 updates this month for its Standard Specifications for Transportation Materials and Methods of Sampling and Testing and AASHTO Provisional Standards – commonly referred to as the Materials Standards publication – which contain specifications, test methods, and provisional standards commonly used in the construction of highway facilities.
Two additional 2019 updates will be released in June and July this year.
The April 2019 update includes three new and 16 revised standards, while revising several key sections, including: Hydraulic Cement and Lime; Fresh Concrete; Hardened Concrete; Pavement Measurement; Bridge and Pavement Preservation; and Quality Assurance and Environmental.
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. Customers can purchase a subscription via the online AASHTO Store at https://store.transportation.org, searching by Item Code HM-WB.
Customers may purchase either a single-user license or choose among several multiple-user license options, which offer deeper price discounts, including: a 25 percent for a two-user license; a 33 percent discount for a three-user license; and a nearly 40 percent discount for a twenty-five-user license.
