Bituminous mixtures - Test methods for hot mix asphalt - Part 15: Determination of the segregation sensitivity

Le présent document décrit une méthode d''essai pour la détermination de la qualité de malaxage et de la tendance à la ségrégation des mélanges bitumineux à chaud. Un échantillon chaud du mélange est placé dans une trémie conique. On ouvre la plaque du fond de la trémie pour laisser tomber le mélange sur une plate-forme, formant ainsi un tas conique. Une trappe est ouverte dans la plate-forme sous le centre du tas. La partie contenant les éléments fins à l''intérieur du tas s''écoule par l''ouverture. On détermine la teneur en bitume et la granulométrie de la partie intérieure plus fine ainsi que la partie plus grossière restante du mélange bitumineux. La valeur de la ségrégation est calculée comme étant la différence entre la teneur en bitume de la partie contenant les éléments fins et celle de la partie contenant les éléments grossiers.

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!
