Bituminous mixtures - Test methods - Part 42: Amount of foreign matter in reclaimed asphalt

This European Standard specifies a visual method of determining the amount and components of coarse foreign matter in reclaimed asphalt. A method for determining the amount and components of finer foreign matter in reclaimed asphalt is given in Annex A. This method does not completely categorise the foreign matter that can occur in asphalt.
NOTE 1   For the use of reclaimed asphalt in asphalt mixtures, it is important to know the components in the reclaimed asphalt and to what extent coarse foreign matter is present that can influence the properties of the asphalt mix.
NOTE 2   The method is not intended to categorise all foreign materials but rather to ensure that the amount of coarse foreign materials are minimised.

Asphalt - Prüfverfahren - Teil 42: Menge der Fremdpartikel in Ausbauasphalt

Dieses Dokument legt ein Sichtprüfverfahren zur Bestimmung des Gehalts an groben Fremdstoffen und deren Bestandteile in Ausbauasphalt fest. Ein Verfahren zur Bestimmung des Gehalts an feineren Fremdstoffen in Ausbauasphalt und deren Bestandteile wird in Anhang A angegeben. Dieses Verfahren ist nicht dazu geeignet, die Fremdstoffe, die in Ausbauasphalt enthalten sein können, vollständig zu klassifizieren.
ANMERKUNG Für die Verwendung von Ausbauasphalt in Asphalten ist es wichtig zu wissen, welche Bestandteile im Ausbauasphalt enthalten sind, und die Mengenanteile der groben Fremdstoffe zu kennen, die die Eigenschaften des Asphalts beeinflussen können.

Mélanges bitumineux - Méthodes d'essai - Partie 42 : Quantité de matériaux étrangers présents dans les agrégats d'enrobés

Ce document spécifie une méthode visuelle permettant de déterminer la quantité et les composants de matériaux étrangers grossiers dans les agrégats d'enrobés. Une méthode visant à déterminer la quantité et les composants de matériaux étrangers fins dans les agrégats d'enrobés est fournie à l'Annexe A. Cette méthode ne permet pas de classer en catégories la totalité des matériaux étrangers susceptibles d'être présents dans les agrégats d’enrobés.
NOTE En vue de l'utilisation d'agrégats d'enrobés dans les mélanges bitumineux, il est important de connaître les composants de ces agrégats et de savoir dans quelle proportion sont présents les matériaux étrangers grossiers qui peuvent influer sur les propriétés du mélange bitumineux.

1 Scope

This document specifies a visual method of determining the amount and components of coarse

foreign matter in reclaimed asphalt. A method for determining the amount and components of finer

foreign matter in reclaimed asphalt is given in Annex A. This method does not completely categorize

the foreign matter that can occur in reclaimed asphalt.

NOTE For the use of reclaimed asphalt in bituminous mixtures it is important to know the components in

the reclaimed asphalt and to know to what extent coarse foreign matter is present that can influence the

properties of the bituminous mixture.
