1.1 This specification 2 covers asphalt binders graded by performance. Grading designations are related to the LTPPBind Online calculated maximum pavement design temperature, the minimum pavement design temperature, and the traffic loading. Note 1: For more information on LTPPBind Online, see https://infopave.fhwa.dot.gov/Tools/LTPPBindOnline accessed May 23, 2023. 1.2 This specification incorporates Test Method D7405 for determining non-recoverable creep compliance, J nr . “S,” “H,” “V,” or “E” designations must be specified for standard, heavy, very heavy, and extremely heavy traffic loading, respectively. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. Note 2: A guidance document for specifying bodies using R % for elastic properties is under development. Note 3: For asphalt binders graded by penetration at 25 °C, see Specification D946/D946M . For asphalt binders graded by viscosity at 60 °C, see Specification D3381/D3381M . For performance-graded asphalt binder, see Specification D6373 . Note 4: AASHTO R 29 provides non-mandatory information for determining the performance grade of an asphalt binder. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
