Description
1.1 This test method covers the determination of percent recovery and non-recoverable creep compliance of asphalt binders by means of Multiple Stress Creep and Recovery (MSCR) testing. The MSCR test is conducted using the Dynamic Shear Rheometer (DSR) at a specified temperature.
1.2 This standard is appropriate for unaged material, material aged in accordance with Test Method D 2872 (RTFO), material aged in accordance with Practice D 6521 (PAV), and material aged in accordance with both Test Method D 2872 and Practice D 6521.
Note 1 – The majority of development work on this test method was performed on material aged in accordance with Test Method D 2872 (RTFO).
1.3 The percent recovery is intended to provide a means to determine the presence of elastic response and stress dependence of polymer modified and unmodified asphalt binders.
1.4 A precision and bias statement for this standard has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.
1.5 The values stated in SI units are to be considered standard.
1.6 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.
