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 sind für Asphalt mit Gesteinskörnung mit einer oberen Korngröße von höchstens 22 mm anwendbar.
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 Straßenbau-bitumen. Entsprechend den skandinavischen Erfahrungen mit Verfahren A ist die Korrelation zwischen dem Abrieb im Labor und in Feldversuchen nicht gegeben, 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 geeignet. Die Korrelation zwischen dem Abrieb im Labor und in Feldversuchen ist nicht gegeben, wenn kautschukmodifiziertes Bitumen verwendet wird.
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.

4 Method A
4.1 Principle
A cylindrical specimen having a diameter of 100 mm and a height of 30 mm is brought to a temperature
of 5 °C. The specimen is worn by abrasive action during 15 min by 40 steel spheres. The loss of volume
in millilitre is recorded and is reported as the abrasion value.
4.2 Apparatus
Abrasion apparatus according to Figure 1, including a stroke, (43 ± 1) mm, and a connection rod, length
(200 ± 5) mm.
The stroke height shall be measured in a way that possible backlash is included in the stroke height.
The equipment shall be mounted on a concrete foundation, the mass should be at least 300 kg, or be
attached to a concrete floor. If rubber feet are used, they shall be of such quality that the equipment
does not come into self-oscillation.
4.2.1 Sample collar of stainless steel for test specimen with inner diameter (102,0 ± 0,2) mm, to
enable fitting of specimens made by EN 12697-30, and inner height at least 35 mm. Thickness about
6 mm. (Figure 1).
NOTE The measurement for inner diameter is required on new manufactured equipment. Some earlier made
equipment could have an inner diameter that is smaller than the tolerance requirement but it does not have
influence on the wearing surface area; however, the smaller diameter might limit the possibility to enable fitting of
specimens made by EN 12697-30.
