Bituminous mixtures - Test methods - Part 49: Determination of friction after polishing

This document specifies a method to determine the friction at 60 km/h after polishing during a fixed number of passes on surfaces of bituminous mixtures samples, or to follow its evolution as a function of the number of polishing passes.
The samples used are either produced in a laboratory or are cores taken from the site.

Asphalt - Prüfverfahren - Teil 49: Messung der Griffigkeit nach dem Polieren

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Griffigkeit bei 60 km/h nach dem Polieren während einer festgelegten Anzahl an Übergängen auf Oberflächen von Asphaltproben bzw. zur Verfolgung der Entwicklung der Griffigkeit in Abhängigkeit von der Anzahl der Übergänge fest.
Die verwendeten Probekörper werden entweder im Labor hergestellt oder sind vor Ort entnommene Bohrkerne.

Mélanges bitumineux - Méthodes d’essai - Partie 49 : Détermination du frottement après polissage

Le présent document décrit une méthode permettant de déterminer le coefficient de frottement à 60 km/h, après un nombre déterminé de passes de polissage sur les surfaces des échantillons de mélanges bitumineux ou de suivre cette évolution en fonction du nombre de passes de polissage.
Les échantillons utilisés sont soit des éprouvettes confectionnées en laboratoire, soit des carottes prélevées sur le site.

Bitumenske zmesi - Preskusne metode - 49. del: Ugotavljanje tornih sposobnosti po poliranju

Ta dokument opisuje preskusno metodo za ugotavljanje tornih sposobnosti pri 60 km/h po poliranju med določenim številom utrjevanj na površinah vzorcev bitumenskih zmesi ali za spremljanje njihovega razvoja kot funkcije števila prehodov polirne naprave.
Uporabljeni vzorci so ustvarjeni v laboratoriju ali so jedra, odvzeta na mestu uporabe.
OPOMBA:   Ta postopek je bil predhodno poznan kot Wehnerjeva in Schulzejeva metoda (glej [1]).
