Bituminous mixtures - Test methods for hot mix asphalt - Part 49: Determination of friction after polishing

This European Standard describes a test method to determine the friction at 60 km/h after polishing during a fixed number of passes on surfaces of bituminous mixtures samples.
The samples used are either produced in a laboratory or are cores taken from the site.
NOTE   This procedure was previously known as Wehner and Schulze method (see [1]).

Asphalt - Prüfverfahren für Heißasphalt - Teil 49: Messung der Griffigkeit nach Polierung

Diese Europäische Norm beschreibt ein Prüfverfahren zur Bestimmung der Griffigkeit bei 60 km/h nach dem Polieren während einer festgelegten Anzahl an Übergängen auf Oberflächen von Asphaltproben.
Die verwendeten Probekörper werden entweder im Labor hergestellt oder sind vor Ort entnommene Bohrkerne.
ANMERKUNG Dieses Verfahren war ehemals unter der Bezeichnung Wehner/Schulze-Verfahren (siehe [1]) bekannt.

Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 49: Détermination du coefficient de frottement après polissage

La présente Norme européenne décrit une méthode d'essai permettant de déterminer le frottement à 60km/h après un polissage après un nombre déterminé de passes à la surface de l’échantillon de mélanges bitumineux.
Les échantillons utilisés sont soit des échantillons produits en laboratoire, soit des carottes prélevées sur le site.
NOTE   Ce mode opératoire était précédemment connu sous l'appellation "méthode de Wehner et Schulze"(voir [1].
