Bitumens and bituminous binders - Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR)
This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear.
From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus.
This method 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).

Bitumen in bitumenska veziva - Določanje kompleksnega strižnega modula in faznega kota - Dinamični strižni reometer (DSR)
Ta dokument določa splošno metodo uporabe dinamičnega strižnega reometra (DSR) za merjenje reoloških lastnosti bitumenskih veziv. Postopek vključuje določanje kompleksnega strižnega modula in faznega kota veziv v razponu preskusnih frekvenc in preskusnih temperatur pri testiranju v oscilacijskem strigu.
Iz preskusa se izračunata kompleksni strižni modul, |G*|, in njegov fazni kot, δ, pri dani temperaturi in frekvenci, kot tudi komponenti G' in G" kompleksnega strižnega modula.
Ta metoda je uporabna za nepostarana, postarana, stabilizirana in regenerirana bitumenska veziva. Preskusni postopek v skladu s tem dokumentom ni primeren za bitumenska veziva z delci, večjimi od 250 μm (npr. polnilni material, granulirana guma).

Overview
SIST EN 14770:2023/oprA1:2026, Bitumens and bituminous binders - Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR), is a draft European amendment developed by CEN/TC 336. This standard specifies a general method for measuring the rheological properties of bituminous binders using a Dynamic Shear Rheometer (DSR). The procedure involves determining the complex shear modulus (|G|)* and phase angle (δ) of bituminous binders across various test frequencies and temperatures using oscillatory shear. Additionally, the standard outlines the calculation of the components of the complex shear modulus, namely G' (storage modulus) and G" (loss modulus).
The method is suitable for a wide variety of binders, including un-aged, aged, stabilized, and recovered bituminous binders, provided that the sample does not contain particles larger than 250 μm, such as filler material or granulated rubber.
Key Topics
- Dynamic Shear Rheometer (DSR): The standard defines the detailed use of DSR apparatus for precise rheological analysis of bituminous binders.
- Complex Shear Modulus and Phase Angle: Guidelines for measuring |G*| and δ, which represent the viscoelastic behavior of the binder, are elaborated for comprehensive material characterization.
- Sample Preparation: Step-by-step instructions are provided for homogenizing, molding, and storing specimens to ensure reliable and repeatable test results, including storage conditions and minimum/maximum recommended storage times.
- Applicability and Limitations: The methodology does not apply to binders with large particles (over 250 μm), ensuring the test's reliability for bounded homogeneous samples.
- Safety Considerations: The standard emphasizes safe handling practices due to the potential hazards associated with high-temperature operations and the handling of hot bituminous binders.
- Quality Assurance: Recommendations are included for preparing extra test specimens and for steps to avoid contamination and ensure the integrity of results.
Applications
The EN 14770 standard is essential for:
- Asphalt and Pavement Design: Determining the viscoelastic properties of binders informs the performance grading of asphalt and contributes to more durable road surfaces.
- Binder Specification and Quality Control: Manufacturers and laboratories use the DSR method to verify that bituminous binders meet regulatory or customer requirements.
- R&D and Material Development: Researchers rely on this standard when developing new polymer-modified bitumen or evaluating the effects of ageing, additives, and recycling processes.
- Forensics and Failure Analysis: Identifying the root causes of pavement distress by measuring changes in binder rheology due to traffic, environment, or production issues.
- Compliance with European Standards: Industry professionals and compliance officers use this test to ensure their materials align with harmonized CEN standards for construction and infrastructure projects.
Related Standards
For comprehensive binder analysis and quality assurance, consider referencing these related standards:
