Bituminous mixtures - Test methods - Part 16: Abrasion by studded tyres
This document specifies two test methods (method A and method B) for determining the susceptibility of abrasion by studded tyres, tested on cylindrical specimens of bituminous mixtures. The test methods are applicable to bituminous mixtures with aggregate with upper sieve size not exceeding 22 mm.
The tests are applicable to laboratory produced specimens or cores drilled from a slab or pavement.
NOTE 1 Method A originates from the ‘Prall’-method, which has been improved by comprehensive Nordic research work. The method correlates with abrasion in the field when using paving grade bitumen. According to Nordic experience by method A the correlation between laboratory and abrasion in field is not established when polymer modified bitumen or rubber modified bitumen, etc. is used.
NOTE 2 Method B originates from Finnish experience and is suitable also when polymer modified bitumen is used. The correlation between laboratory and abrasion in field is not established when rubber is used.
Asphalt - Prüfverfahren - Teil 16: Abrieb durch Spikereifen
Dieses Dokument legt zwei Prüfverfahren (Verfahren A und Verfahren B) für die Bestimmung der Empfindlichkeit gegenüber dem durch Spikereifen verursachten Abrieb durch Prüfung von zylindrischen Probekörpern aus Asphalt fest. Die Prüfverfahren gelten für Asphalt mit Gesteinskörnung mit einer oberen Korngröße von höchstens 22 mm.
Die Prüfungen sind anwendbar für im Labor hergestellte Probekörper oder für aus Platten oder der Fahrbahnbefestigung entnommene Bohrkernproben.
ANMERKUNG 1 Verfahren A ist vom „Prall“-Verfahren abgeleitet, das durch umfassende skandinavische Forschungs¬arbeiten verbessert wurde. Das Verfahren korreliert mit dem Abrieb in der Praxis bei Verwendung von Straßen¬baubitumen. Entsprechend den skandinavischen Erfahrungen stellt sich der Zusammenhang zwischen dem Abrieb im Labor und in Feldversuchen nicht heraus, wenn polymermodifiziertes Bitumen oder kautschukmodifiziertes Bitumen usw. verwendet wird.
ANMERKUNG 2 Verfahren B beruht auf finnischen Erfahrungen und ist auch bei Verwendung von polymer-modifiziertem Bitumen anwendbar. Die Korrelation zwischen dem Abrieb im Labor und in der Praxis wird bei Einsatz von kautschukmodifiziertem Bitumen nicht bestimmt.
Mélanges bitumineux - Méthodes d'essai - Partie 16 : Abrasion par pneus à crampons
Le présent document spécifie deux méthodes d’essai (méthode A et méthode B) pour déterminer la sensibilité à l’abrasion des pneus à crampons, dont l’essai est effectué sur des éprouvettes cylindriques de mélanges bitumineux. Les méthodes d’essai sont applicables aux mélanges bitumineux contenant des granulats dont la dimension supérieure d’ouverture du tamis ne dépasse pas 22 mm.
Les essais sont applicables aux éprouvettes fabriquées en laboratoire ou aux carottes prélevées dans une dalle ou une chaussée.
NOTE 1 La méthode A provient de la méthode « Prall », qui a été améliorée par des travaux de recherche nordiques approfondis. Cette méthode correspond à l’abrasion sur le terrain lors de l’utilisation de bitume routier usuel. Selon les expériences nordiques menées sur la méthode A, la corrélation entre l’abrasion en laboratoire et l’abrasion sur le terrain n’est pas établie lorsque du bitume ou du caoutchouc modifié par des polymères, etc. est utilisé.
NOTE 2 La méthode B provient d’une expérience finlandaise et est notamment adaptée lors de l’utilisation de bitume modifié par des polymères. La corrélation entre l’abrasion en laboratoire et l’abrasion sur le terrain n’est pas établie lorsque du caoutchouc est utilisé.
