1.2 The percent recovery at multiple stress levels is intended to determine the presence of elastic response and stress dependence of bituminous binders.
1.3 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.
1.4 This European 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 European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 Ta preskusna metoda zajema določevanje deleža ohranjene aktivnosti ter skladnosti nepovratnega lezenja bitumna in bitumenskih veziv s ponavljajočim obremenilnim in razbremenilnim preskusom lezenja (MSCR). Preskus MSCR se izvede z dinamičnim strižnim reometrom (DSR) v načinu lezenja pri določeni temperaturi.
1.2 Ta standard je primeren za nestaran material, staran material v skladu s standardom EN 12607-1 (RTFOT), staran material v skladu s standardom EN 14769 (PAV) ter staran material v skladu s standardoma EN 12607-1 in EN 14769.
Za proizvodnjo materiala za ta standard je mogoče uporabiti tudi druge metode staranja, na primer iz standarda EN 15323 (RCAT).
1.3 Delež ohranjene aktivnosti pri več stopnjah odpornosti je namenjen določevanju prisotnosti elastičnega odziva in odvisnosti na odpornost bitumenskih veziv.
1.4 Skladnost nepovratnega lezenja pri več stopnjah odpornosti označuje občutljivost na stalno deformacijo in odvisnosti na odpornost bitumenskih veziv.
1.5 Ta standard ne obravnava vseh morebitnih varnostnih težav, ki se nanašajo na njegovo uporabo. Za vzpostavitev ustreznih varnostnih in zdravstvenih praks ter za določitev uporabnosti regulativnih omejitev pred uporabo je odgovoren uporabnik tega standarda.

Overview
EN 16659:2015 defines the Multiple Stress Creep and Recovery Test (MSCRT) for the characterization of bitumen and bituminous binders. The method uses a Dynamic Shear Rheometer (DSR) in stress-controlled creep mode to determine percent recovery and non‑recoverable creep compliance (Jnr) at multiple stress levels and specified temperatures. These metrics indicate elastic response and sensitivity to permanent deformation - properties directly relevant to pavement rutting resistance and binder performance under repeated traffic loading.
Key Topics and Requirements
- Test objective: Measure percent recovery (%R) and non-recoverable creep compliance (Jnr) to assess elastic behavior and permanent deformation susceptibility.
- Instrumentation: Dynamic Shear Rheometer (DSR) running in stress-controlled mode with temperature control (5 °C–85 °C capability) and data sampling at least every 0.1 s during creep.
- Geometry and gap: 25 mm parallel plate geometry with 1.00 mm gap (±0.01 mm).
- Loading protocol: Ten 1 s creep / 9 s recovery cycles at 0.1 kPa, followed by ten cycles at 3.2 kPa (standard durations and stress levels specified).
- Temperatures: Standard test temperatures include 50 °C, 60 °C, 70 °C or 80 °C; other temperatures may be used for comparison.
- Sample prep & handling: Sampling per EN 58, preparation per EN 12594; strict heating limits, storage delays (min 30 min, max 24 h), and special instructions for polymer-modified and fluxed binders.
- Quality & precision: Includes requirements for rheometer calibration, repeatability and reproducibility assessment (ISO 5725-2 referenced).
- Safety note: Standard does not replace laboratory safety practices - users must manage high-temperature handling risks.
Applications and Users
- Practical uses:
- Quality control and acceptance testing of asphalt binders.
- Screening of polymer-modified binders for elastic response.
- Comparative evaluation of binder sensitivity to permanent deformation (indicator of rutting potential).
- Research and development of binder formulations and performance grading.
- Typical users:
- Materials and pavement testing laboratories
- Bitumen manufacturers and suppliers
- Highway authorities and pavement engineers
- R&D teams working on asphalt binder modifiers and performance specifications
