DIN EN 16659:2013-09

This test method covers the determination of percent recovery and non-recoverable creep compliance of bitumen and bituminous binders by means of Multiple Stress Creep and Recovery (MSCR) testing. The MSCR test is conducted using the Dynamic Shear Rheometer (DSR) in creep mode at a specified temperature. This standard is appropriate for unaged material, material aged in accordance with EN 12607-1 (RTFOT), material aged in accordance with EN 14769 (PAV), material aged in accordance with both EN 12607-1 and EN 14769. Other ageing methods, for example EN 15323 (RCAT) can also be used to produce material for this standard. The percent recovery at multiple stress levels is intended to determine the presence of elastic response and stress dependence of bituminous binders.The non-recoverable creep compliance at multiple stress levels is intended as an indicator for the sensitivity to permanent deformation and stress dependence of bituminous binders. 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.
