Bituminous mixtures - Test methods - Part 47: Determination of the ash content of natural asphalts
This document describes a test method to determine the ash content in natural asphalts (including lake asphalts), binders containing natural asphalts or bitumens. For the method to apply, it is essential that any mineral matter in the binder be finely divided and cannot exceed 45 % by mass.
Asphalt - Prüfverfahren - Teil 47: Bestimmung des Aschegehaltes von Naturasphalt
Dieses Dokument beschreibt ein Prüfverfahren zur Bestimmung des Aschegehaltes von Naturasphalt (einschließlich Naturasphalt aus Asphaltseen) und von Bindemitteln, die Naturasphalt oder Erdölbitumen enthalten. Damit das Verfahren anwendbar ist, müssen die im Bindemittel enthaltenen Mineralstoffe fein verteilt sein und ihr Anteil darf einen Massenanteil von 45 % nicht überschreiten.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 47 : Détermination de la teneur en cendres des bitumes naturels
La présente Norme Européenne décrit une méthode d’essai destinée à déterminer la teneur en cendres des bitumes naturels ainsi que des liants comprenant des bitumes naturels. Pour pouvoir appliquer la méthode, il est essentiel que toute matière minérale présente dans le liant soit finement divisée et ne pas dépasser 45% en masse.
