This test method covers the determination of percent recovery and non-recoverable creepcompliance of asphalt binders by means of the Multiple Stress Creep Recovery (MSCR) test. TheMSCR test is conducted using the Dynamic Shear Rheometer (DSR) at a specified temperature. Itis intended for use with residue from T 240 (Rolling Thin-Film Oven Test (RTFOT)). The testmethod may also be run on residue from R 28 (Pressurized Aging Vessel (PAV)).

Note 1–The majority of the development work on this test method was performed on materialaged according to T 240 (RTFO).

The percent recovery value is intended to provide a means for determining the elastic response andstress dependence of polymer modified and unmodified asphalt binders.

he values stated in SI units are to be regarded as the standard.
