EN 16659:2026 – Bitumens and Bituminous Binders – Multiple Stress Creep and Recovery Test (MSCRT)
Bitumens and bituminous binders - Multiple Stress Creep and Recovery Test (MSCRT)
EN 16659:2026 updates the methodology for evaluating the elastic recovery and deformation resistance of bituminous binders, essential materials in road construction and maintenance. The Multiple Stress Creep and Recovery Test (MSCR) is conducted using a dynamic shear rheometer (DSR), providing more precise measures of a binder’s ability to resist permanent deformation (rutting) under repeated traffic loading.
This revision accounts for both aged and unaged binders and introduces controls for particle size, improved specimen preparation, and revised temperature ranges for testing. These updates ensure that test results are more consistent and better reflect real-world conditions, thereby improving material specifications for asphalt pavements and ensuring long-term performance.
This standard is highly relevant to:
- Asphalt and bitumen product manufacturers
- Civil engineering laboratories
- Transportation agencies and road authorities
- Quality assurance professionals in paving projects
With detailed requirements for apparatus, specimen handling, and reporting, EN 16659:2026 enables better decision-making for infrastructure investment and maintenance.
Key highlights:
- Standardizes MSCR test for all bituminous binders
