Bituminous mixtures - Test methods for hot mix asphalt - Part 24: Resistance to fatigue
This document specifies the methods for characterising the fatigue of bituminous mixtures by alternative tests, including bending tests and direct and indirect tensile tests. The tests are performed on compacted bituminous material under a sinusoidal loading or other controlled loading, using different types of specimens and supports.
The procedure is used to rank bituminous mixtures on the basis of resistance to fatigue, as a guide to relative performance in the pavement, to obtain data for estimating the structural behaviour in the road and to judge test data according to specifications for bituminous mixtures.
Because this document does not impose a particular type of testing device, the precise choice of the test conditions depends on the possibilities and the working range of the used device. For the choice of specific test conditions, the requirements of the product standards for bituminous mixtures shall be respected. The applicability of this document is described in the product standards for bituminous mixtures. Results obtained from different test methods are not assured to be comparable.
Asphalt - Prüfverfahren für Heißasphalt - Teil 24: Beständigkeit gegen Ermüdung
Dieses Dokument legt die Verfahren fest zur Charakterisierung der Ermüdung von Asphalt durch verschiedene Prüfungen, einschließlich Biegeprüfungen und Prüfungen der direkten sowie der indirekten Zug¬festigkeit. Die Prüfungen werden an verdichtetem Asphalt unter sinusförmiger oder einer anderen kontrollier¬ten Belastung unter Verwendung verschiedener Probekörpertypen und Auflagerungen vorgenommen.
Das Verfahren dient zur Einstufung von Asphalt nach seiner Beständigkeit gegen Ermüdung, als Hinweis auf sein relatives Leistungsvermögen in der Fahrbahnbefestigung, um Daten zur Abschätzung des Tragverhal¬tens in der Straße zu erhalten und die Prüfdaten nach den für Asphalt geltenden Festlegungen zu beurteilen.
Da dieses Dokument keinen bestimmten Prüfgerätetyp vorschreibt, hängt die genaue Auswahl der Prüfbedingungen von den Möglichkeiten und dem Arbeitsbereich des im betreffenden Fall verwendeten Prüf¬geräts ab. Bei der Auswahl der jeweiligen Prüfbedingungen müssen die Anforderungen der Produktnormen für Asphalt berücksichtigt werden. Die Anwendbarkeit dieses Dokumentes ist in den Produktnormen für Asphalt beschrieben. Die mit verschiedenen Prüfverfahren erhaltenen Prüfergebnisse sind nicht notwendiger¬weise miteinander vergleichbar.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné a chaud - Partie 24: Résistance a la fatigue
Le présent document spécifie les méthodes qui sont utilisées pour caractériser la fatigue des mélanges bitumineux par différents types d’essais, dont des essais de flexion et des essais de traction directe et indirecte. Les essais sont réalisés sur des matériaux bitumineux compactés, au moyen d’une charge sinusoidale ou d’une autre charge contrôlée, en utilisant différents types d’éprouvettes et de supports.
La procédure est utilisée pour classer les mélanges bitumineux selon leur résistance a la fatigue, prise comme guide comparatif des performances dans les structures de chaussée, de maniere a obtenir des données permettant d’estimer le comportement structurel du matériau dans la chaussée et de pouvoir juger les résultats d’essais en fonction des spécifications des mélanges bitumineux.
Comme le présent document n’impose pas un type de dispositif d’essai particulier, le choix précis des conditions d’essai dépend des possibilités et de la plage de fonctionnement du dispositif utilisé. Pour le choix des conditions d’essai spécifiques, il sera nécessaire de respecter les criteres des normes produit des mélanges bitumineux. Le domaine d’application du présent document est décrit dans les normes produit des mélanges bitumineux. Il n’est pas certain que les résultats obtenus selon les différentes méthodes d’essai soient comparables.
