Bituminous mixtures - Test methods - Part 1: Soluble binder content

This document describes test methods for the determination of the soluble binder content of samples of bituminous mixtures.
The test methods described are suitable for quality control purposes during the production of plant mix and for checking compliance with a product specification.
For the analysis of mixtures containing modified binders, the guidance of Annex D should be followed.

Asphalt - Prüfverfahren - Teil 1: Löslicher Bindemittelgehalt

Dieses Dokument beschreibt Prüfverfahren zur Bestimmung des löslichen Bindemittelgehaltes in Proben aus Asphalt.
Die beschriebenen Prüfverfahren sind zur Qualitätskontrolle während der Herstellung des Mischgutes sowie zur Überprüfung der Übereinstimmung mit einer Produktspezifikation geeignet.
Zur Untersuchung von Gemischen, welche modifizierte Bindemittel enthalten, sollten die Hinweise in Anhang D beachtet werden.

Mélanges bitumineux - Méthodes d'essai - Partie 1 : Teneur en liant soluble

Le présent document décrit des méthodes d’essai pour déterminer la teneur en liant soluble d’échantillons de matériaux enrobés.
Les méthodes d’essai décrites sont applicables pour la maîtrise de la qualité de production en usine et pour les vérifications de conformité aux spécifications des produits.
Pour l'analyse des mélanges contenant des liants modifiés, il convient de suivre les recommandations données en Annexe D.
