Scope

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.

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 method is applicable to un-aged, aged, stabilised 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).

Purpose

Revision decision 24/2021 taken unanimously on 2021-11-17 at CEN/TC 336 19th plenary meeting further to the outcome of 2021 systematic review taking into account all comments received as documented in N982 (need to update and align with the ongoing revision project of the DSR test method prEN 14770) and the recommendation of WG 1 for a PWI, noting that WG 1 was offering the available resource of motivated experts and a project leader. Drafting was so far at preliminary stage and, based on the progress of works, WG 1 requested on 2022-11-17 to activate the PWI (Recommendation 09/2022 in N1111), this was endorsed on 2022-11-30 by CEN/TC 336 at the 20th Plenary meeting by the Decision 28/2022 N1132.
