Surface dressing - Test methods - Part 1: Rate of spread and accuracy of spread of binder and chippings
This European Standard specifies test methods for determining the rates of spread and accuracy of spread of binder and chippings of a surface dressing on a section of road at a given time. It is also applicable to surface dressings on airfields and other trafficked areas.
The test methods are used on site to check the ability of binder sprayers and chipping spreaders to meet the intended rates of spread and tolerances and coefficients of variation.
The test methods for measuring the rates of spread and accuracy of spread of binders and chippings are not applicable to combined chipping-binder spreaders.
Oberflächenbehandlung - Prüfverfahren - Teil 1: Dosierung und Querverteilung von Bindemitteln und Splitt
Diese Europäische Norm legt Prüfverfahren für die Bestimmung der Dosierung und Genauigkeit der Verteilung von Bindemitteln und Splitt bei einer Oberflächenbehandlung zu einem bestimmten Zeitpunkt und in einem bestimmten Abschnitt einer Straßenoberfläche fest. Sie ist auch für Oberflächenbehandlungen auf Flugplätzen und anderen Verkehrsflächen anwendbar.
Die Prüfungen werden auf Baustellen benutzt, um zu überprüfen, ob die Bindemittel- und Splitt-verteiler die angegebenen Dosierungen und Variationskoeffizienten der Querverteilung einhalten.
Die Prüfverfahren für die Dosierung und Querverteilung von Bindemitteln und Splitt sind nicht für kombinierte Splitt-Bindemittel-Verteilergeräte anwendbar.
Enduits superficiels d'usure - Méthodes d'essai - Partie 1: Taux d'épandage et régularité transversale du liant et des gravillons
La présente Norme européenne spécifie les méthodes d'essai à employer pour la détermination des taux d'épandage et de la régularité transversale du liant et des gravillons d'un enduit superficiel d'usure sur une section de route à un instant donné. Elle s'applique également aux enduits superficiels d'usure des terrains d'aviation et autres zones de trafic.
Les méthodes d'essai sont utilisées sur le site pour contrôler la capacité des répandeuses de liant et épandeuses de gravillons à respecter les taux d'épandage, tolérances et coefficients de variation prescrits.
Les méthodes d'essai recommandées pour la mesure des taux d'épandage et de la régularité transversale des liants et des gravillons ne s'appliquent pas aux épandeuses mixtes de gravillons et de liants.
