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 (RTFO), material aged in accordance with Practice (PAV), and material aged in accordance with both Test Method and Practice .
Note 1: The majority of development work on this test method was performed on material aged in accordance with Test Method (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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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.
