Bituminous mixtures - Test methods for hot mix asphalt - Part 11: Determination of the affinity between aggregate and bitumen

This European Standard specifies procedures for the determination of the affinity between aggregate and bitumen and its influence on the susceptibility of the combination to stripping. This property is intended to be of assistance to the designer for mixture design rather than as a type test. Susceptibility to stripping, as determined by these procedures, is an indirect measure of the power of a binder to adhere to various aggregates, or of various binders to adhere to a given aggregate. The procedures can also be used to evaluate the effect of moisture on a given aggregate-binder combination with or without adhesion agents including liquids, such as amines, and fillers, such as hydrated lime or cement.
In the rolling bottle method, the affinity is expressed by visual registration of the degree of bitumen coverage on uncompacted bitumen-coated mineral aggregate particles after influence of mechanical stirring action in the presence of water.
NOTE 1   The rolling bottle test is a simple but subjective test and suitable for routine testing. It is not appropriate for aggregates that are highly abrasive.
In the static test method, the affinity is expressed by visual registration of the degree of bitumen coverage on uncompacted bitumen-coated mineral aggregate particles after storage in water.
NOTE 2   The static test is a simple but subjective test that is less precise generally but can cope with high PSV-aggregates.
In the boiling water stripping test method, the affinity is expressed by determining the degree of bitumen-coverage on uncompacted bitumen-coated aggregate after immersion in boiling water under specified conditions.
NOTE 3   The boiling water stripping test is an objective test and has a high precision. However, it is a more specialist test because it requires greater skill of the operatives and uses chemicals as reagent. The latter point may also imply extra health and safety considerations. (continued)

Asphalt - Prüfverfahren für Heißasphalt - Teil 11: Bestimmung der Affinität von Gesteinskörnungen und Bitumen

Diese Europäische Norm legt ein Verfahren fest zur Bestimmung der Affinität von Gesteinskörnungen und Bitu-men
und des Einflusses dieser Affinität auf die Anfälligkeit für das Ablösen des Bindemittels von der Gesteins-körnung.
Diese Eigenschaft sollte vom Entwickler anstelle von Eignungsprüfungen in erster Linie für die Erstel-lung
von Mischgutrezepturen verwendet werden. Die nach diesen Verfahren bestimmte Anfälligkeit für das
Ablösen des Bindemittels von der Gesteinskörnung ist ein indirektes Maß für das Haftvermögen dieses Binde-mittels
an verschiedenen Gesteinskörnungen oder für das Haftvermögen verschiedener Bindemittel an einer
bestimmten Gesteinskörnung. Diese Verfahren können auch zur Beurteilung der Auswirkung von Feuchte auf
bestimmte Kombinationen aus Gesteinskörnung und Bindemittel mit oder ohne Haftvermittler, einschließlich
Flüssigkeiten, wie z. B. Aminen, und Zusätze, wie z. B. hydratisierter Kalk oder Zement, herangezogen
werden.

Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 11: Détermination de l'affinité granulat-bitume

Le présent document spécifie des modes opératoires pour déterminer l’affinité entre granulat et bitume et son influence sur la susceptibilité de la combinaison au désenrobage. Cette propriété est plutôt destinée à aider le concepteur à formuler le mélange qu’à représenter un essai pour épreuve de formulation. La susceptibilité au désenrobage, telle que déterminée par ces modes opératoires, est une mesure indirecte de la capacité du liant à adhérer à différents granulats ou de différents liants à adhérer à un granulat donné. Les modes opératoires peuvent également être utilisés pour évaluer l’effet de l’eau sur une combinaison granulats-liant avec ou sans dope d’adhésivité que ce soit des liquides comme les amines, des fillers comme la chaux hydratée ou le ciment.
Dans la méthode «de la bouteille tournante», l’affinité est exprimée par le degré d’enrobage de bitume, déterminé visuellement, de granulats minéraux enrobés de bitume, non compactés, après une agitation mécanique en présence d’eau.
NOTE 1   L’essai «de la bouteille tournante» est simple mais subjectif et approprié pour des essais de routine. Il ne convient pas pour les granulats hautement abrasifs.
Dans la méthode de l’essai statique, l’affinité est exprimée par le degré d’enrobage de bitume, déterminé visuellement, de granulats minéraux enrobés de bitume, non compactés après le stockage dans l’eau.
NOTE 2   L’essai statique est simple mais subjectif ; il est généralement moins précis mais est approprié aux granulats à haut coefficient de polissage accéléré.
Dans la méthode de l’essai de désenrobage à l’eau bouillante, l’affinité est exprimée par le degré d’enrobage de bitume de granulats minéraux enrobés de bitume, non compactés après immersion dans l’eau bouillante dans des conditions spécifiées.
NOTE 3   L’essai de désenrobage à l’eau bouillante est objectif et très précis. Toutefois, il s’agit d’un essai plus spécialisé car il exige un personnel plus qualifié et il utilise des réactifs chimiques. Ce de
