Tests for mechanical and physical properties of aggregates - Part 8: Determination of the polished stone value
This Standard describes the reference method used for type testing and in cases 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 may be used provided that an
appropriate working relationship with the reference method has been established.
Annex A describes an optional method for the determination of the aggregate abrasion value (AAV).
NOTE The AAV method should be used 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.
Prüfverfahren für mechanische und physikalische Eigenschaften von Gesteinskörnungen - Teil 8: Bestimmung des Polierwertes
Diese Norm legt das für die Erstprüfung und in Streitfällen 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, dürfen andere Verfahren
angewendet werden, sofern ein ausreichender Zusammenhang zum Referenzverfahren nachgewiesen
wurde.
Im Anhang A ist ein optionales Verfahren zur Bestimmung des Abriebwertes der Gesteinskörnung (en: aggregate
abrasion value, AAV) festgelegt.
ANMERKUNG Das AAV-Verfahren sollte angewendet werden, wenn bestimmte Arten von griffigen Gesteinskörnungen
(üblicherweise Gesteine mit einem PSV von 60 oder darüber), die anfällig gegen Abrieb unter Verkehrsbelastung sind,
benötigt werden.
Essais pour déterminer les caractéristiques mécaniques et physiques des granulats - Partie 8: Détermination du coefficient de polissage accéléré
La présente norme décrit la méthode de référence utilisée pour les essais de type 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 peuvent être utilisées, à condition qu’une relation appropriée avec la méthode de référence ait été établie. Des exemples de méthodes d’essai avancées sont donnés dans l’Annexe F.
L’Annexe A décrit une méthode facultative pour la détermination de la valeur d’abrasion des granulats (AAV).
NOTE Il convient d’utiliser la méthode de l’AAV 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.

3 Definitions For the purposes of this document the following definitions apply. 3.1 test specimen sample used in a single determination when a test method requires more than one determination of a property 3.2 batch production quantity, a delivery quantity, a partial delivery quantity (railway wagon-load, lorry-load, ship's cargo) or a stockpile produced at one time under conditions that are presumed uniform NOTE With a continuous process the quantity produced during an agreed period is treated as a batch. SIST EN 1097-8:2009
The test is carried out on aggregate passing a 10 mm sieve and retained on a 7,2 mm grid sieve, and is in two parts: a) test specimens are subjected to a polishing action in an accelerated polishing machine; b) the state of polish reached by each specimen is measured by means of a friction test. The PSV is then calculated from the friction determinations. 5 Sampling The sample submitted to the laboratory for the test shall be obtained from a batch of normal production from the sour
