Bitumen and bituminous binders - Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR)

Le présent document prescrit plusieurs méthodes faisant appel à un rhéomètre à cisaillement dynamique (DSR) pour mesurer certaines caractéristiques rhéologiques des bitumes neufs, après vieillissement artificiel ou récupérés d'un enrobé et des liants bitumineux, modifiés ou non, fluidifiés ou non, récupérés d'une émulsion. La procédure repose sur la détermination du module complexe en cisaillement et de l'angle de phase des liants.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

  • mandatory clauses to satisfy,
  • non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!


What is the Redline format?
The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.


The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
