ASTM WK46865

    New Specification for Performance-Graded Asphalt Binder Using the Multiple Stress Creep and Recovery Test

    (What is a Work Item?)

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



    WK46865

    1. Scope

    1.1 This specification2 covers asphalt binders graded by performance. Grading designations are related to the LTPPBind calculated maximum pavement design temperature, the minimum pavement design temperature and the traffic loading. 1.2 This specification incorporates Test Method D7405 for determining non-recoverable creep compliance, Jnr. S, H, V, or E designations must be specified for standard, high, very high and extremely high traffic loading respectively. NOTE 1A guidance document for specifying bodies using R% for elastic properties is under development. NOTE 2For asphalt binders graded by penetration at 25C, see Specification D946. For asphalt binders graded by viscosity at 60C see Specification D3381. For Performance-Graded Asphalt Binder, see Specification D6373. NOTE 3AASHTO R 29 provides non-mandatory information for determining the performance grade of an asphalt binder.
