Tests for mechanical and physical properties of aggregates - Part 8: Determination of the polished stone value

This document describes the reference method used for type testing and in case of dispute for determining the polished stone value (PSV) of a coarse aggregate used in road surfacings. For other purposes, in particular factory production control, other methods are possible provided that an appropriate working relationship with the reference method has been established. Examples of advanced test methods can be found in the Bibliography.
Annex A describes an optional method for the determination of the aggregate abrasion value (AAV).
NOTE 1   The AAV method is suitable to use when particular types of skid resistant aggregates, (typically those with a PSV of 60 or greater) which can be susceptible to abrasion under traffic, are required.
The sample is taken from normal run of production from the plant.
NOTE 2   Chippings that have been freshly crushed in the laboratory or recovered from bituminous materials may give misleading results.

Prüfverfahren für mechanische und physikalische Eigenschaften von Gesteinskörnungen - Teil 8: Bestimmung des Polierwertes

Dieses Dokument legt das für die Erstprüfung und im Streitfall anzuwendende Referenzverfahren für die Bestimmung des Polierwerts (en: polished stone value, PSV) einer groben Gesteinskörnung für Straßenoberflächen fest. Für andere Zwecke, speziell im Rahmen der werkseigenen Produktionskontrolle, sind auch andere Verfahren möglich, sofern ein ausreichender Zusammenhang zum Referenzverfahren nachgewiesen wurde. Beispiele für fortschrittliche Prüfverfahren können den Literaturhinweisen entnommen werden.
Im Anhang A ist ein optionales Verfahren zur Bestimmung des Abriebwertes einer Gesteinskörnung (en: aggregate abrasion value, AAV) beschrieben.
ANMERKUNG 1   Das AAV-Verfahren ist geeignet, wenn bestimmte Arten von griffigen Gesteinskörnungen (üblicherweise Gesteine mit einem PSV von 60 oder darüber), die anfällig gegen Abrieb unter Verkehrsbelastung sein können, benötigt werden.
Die Probe wird aus der normalen Produktion im Werk entnommen.
ANMERKUNG 2   Frisch im Laboratorium gebrochenes oder aus Asphalt rückgewonnenes Material kann zu verfälschenden Ergebnissen führen.

Essais pour déterminer les caractéristiques mécaniques et physiques des granulats - Partie 8 : Détermination du coefficient de polissage accéléré

Ce document décrit la méthode de référence utilisée pour les essais de type initiaux et en cas de litige pour déterminer le coefficient de polissage accéléré (PSV) des gravillons utilisés dans les revêtements des routes. À d’autres fins, en particulier pour le contrôle de la production en usine, d’autres méthodes sont envisageables sous réserve qu’une corrélation appropriée avec la méthode de référence ait été établie. Des exemples de méthodes d'essai avancées sont disponibles dans la bibliographie.
L'Annexe A décrit une méthode facultative pour la détermination de la valeur d’abrasion des granulats (AAV).
NOTE 1 La méthode AAV peut être utilisée lorsque des types particuliers de granulats antidérapants (ceux, généralement, dont le PSV est égal ou supérieur à 60) sensibles à l’abrasion occasionnée par la circulation, sont exigés.
