Description / Abstract:
This test method covers the determination of percent recovery
and nonrecoverable creep compliance of asphalt binders by means of
the Multiple Stress Creep Recovery (MSCR) test. The MSCR test is
conducted using the Dynamic Shear Rheometer (DSR) at a specified
temperature. It is intended for use with residue from T 240
(Rolling Thin-Film Oven Test (RTFOT)).
The percent recovery value is intended to provide a means for
determining the elastic response and stress dependence of polymer
modified and unmodified asphalt binders.
The values stated in SI units are to be regarded as the
standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
