    (What is a Work Item?)

    Developed by Subcommittee: D04.40 | Committee D04 | Contact Staff Manager



    WK46865

    1. Scope

    1.1 This specification covers asphalt binders graded by performance. Grading designations are related to the LTPPBind algorithm maximum pavement design temperature, the minimum pavement design temperature, and traffic loading. 1.2 This specification incorporates Test Method D7405 for determining nonrecoverable creep compliance, Jnr. S, H, V, or E designations shall be specified for standard, high, very high, and extremely high traffic-loading, respectively. 1.3 To ensure that the asphalt binder exhibits elastic response, the specifying agency may require compliance with Appendix X1. NOTE 1-For asphalt cements graded by penetration at 25C, see Specification D946. For asphalt cements graded by viscosity at 60C, see Specification D3381. For performance-graded asphalt binder, see Specification D6373. NOTE 2-AASHTO R29 provides nonmandatory information for determining the performance grade of an asphalt binder.

    State agencies will use this standard.
