1. Scope |
1.1 This specificationNote 1:For more information on LTPPBind online, see https://infopave.fhwa.dot.gov/Tools/LTPPBindOnline accessed June 10, 2020. 1.2This specification incorporates Test Method D7405 for determining non-recoverable creep compliance, Jnr. S, H, V, or E designations must be specified for standard, heavy, very heavy, and extremely heavy traffic loading, respectively. 1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4The 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 25C, see
Specification D946/D946M. For
asphalt binders graded by viscosity at 60C, 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.
1.5This 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. |
