BS EN 16659:2026

This standard BS EN 16659:2026 Bitumens and bituminous binders. Multiple Stress Creep and Recovery Test (MSCRT) is classified in these ICS categories:

• 91.100.50 Binders. Sealing materials
• 75.140 Waxes, bituminous materials and other petroleum products

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). WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices, workers protection, and to determine the applicability of regulatory limitations prior to use. The use of this document involves handling of apparatus and binders at very high temperatures.
