Bituminous mixtures - Test methods for hot mix asphalt - Part 22: Wheel tracking

This European Standard describes test methods for determining the susceptibility of bituminous materials to deform under load. The test is applicable to mixtures with upper sieve size less than or equal to 32 mm.
The tests are applicable to specimens that have either been manufactured in a laboratory or cut from a pavement; test specimens are held in a mould with their surface flush with the upper edge of the mould.
The susceptibility of bituminous materials to deform is assessed by the rut formed by repeated passes of a loaded wheel at constant temperature. Three alternative types of device can be used according to this standard: large-size devices, extra large-size devices and small-size devices. With large-size devices and extra large-size devices, the specimens are conditioned in air during testing. With small-size devices, specimens are conditioned, in either air or water.
NOTE   Large-size and extra large-size devices are not suitable for use with cylindrical cores.

Asphalt - Prüfverfahren für Heißasphalt - Teil 22: Spurbildungstest

Diese Europäische Norm beschreibt Prüfverfahren zur Bestimmung der Verformungsanfälligkeit von Asphalt bei Belastung. Das Verfahren ist auf Asphalt mit einem Größtkorn von maximal 32 mm anwendbar.
Die Prüfungen sind auf Probekörper anwendbar, die entweder in einem Labor hergestellt oder aus einer Fahr-bahnbefestigung geschnitten wurden; die Probekörper werden so in Prüfformen gelegt, dass ihre Oberflächen mit der Oberkante der Form bündig abschließen.
Die Verformungsanfälligkeit von Asphalt wird anhand einer Spurrinne geprüft, die durch wiederholte Über-gänge eines belasteten Rades bei konstanter Temperatur erzeugt wird. Nach dieser Norm können drei ver-schiedene Prüfgeräte verwendet werden: das Gerät mit großem Rad, das Gerät mit besonders großem Rad und das Gerät mit kleinem Rad. Bei Verwendung der Geräte mit großem und besonders großem Rad werden die Probekörper während der Prüfung an der Luft klimatisiert. Bei Verwendung des Geräts mit kleinem Rad werden die Probekörper entweder im Wasser oder an der Luft klimatisiert.
ANMERKUNG   Die Geräte mit großem und besonders großem Rad sind nicht für die Prüfung von zylindrischen Bohr-kernen geeignet.

Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 22 : Essai d’orniérage

La présente Norme européenne décrit les méthodes d'essai permettant de déterminer le comportement en déformation des matériaux bitumineux soumis à des charges roulantes. Cet essai s'applique aux mélanges dont les plus grandes dimensions granulaires sont inférieures ou égales à 32 mm.
Ces essais peuvent être effectués sur des éprouvettes qui ont été fabriquées en laboratoire ou prélevées sur une chaussée ; les éprouvettes sont placées dans un moule, leur surface affleurant la partie supérieure du moule.
Le comportement en déformation des matériaux bitumineux est évalué par la profondeur de l'ornière qui se forme suite à des passages répétés d'une charge roulante à température constante. Trois types de dispositifs peuvent être utilisés conformément à la présente norme : des dispositifs de grandes dimensions, des dispositifs extra-larges et des dispositifs de petites dimensions. Avec les dispositifs de grandes dimensions et les dispositifs extra-larges, les éprouvettes sont conditionnées à l'air pendant l'essai. Avec les dispositifs de petites dimensions, elles sont conditionnées soit à l'air, soit dans l'eau.
NOTE   Les dispositifs de grandes dimensions et les dispositifs extra-larges ne sont pas adaptés pour l’essai d’éprouvettes cylindriques.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 227.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.
