Anotace

This document specifies a test method for the determination of per cent recovery and non-recoverable creep compliance of bitumens and bituminous binders by means of a Multiple Stress Creep and Recovery (MSCR) test. The MSCR test is conducted using the Dynamic Shear Rheometer (DSR) in creep mode at a specified temperature.
The per cent recovery at multiple shear stress levels is intended to determine the presence of elastic response and the stress dependence of bituminous binders. The non-recoverable creep compliance at multiple shear stress levels is intended as an indicator for the sensitivity to permanent deformation and stress dependence of bituminous binders.
This document is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 µm (e.g. filler material, granulated rubber)
