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

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.

Tests for general properties of aggregates - Part 3: Procedure and terminology for simplified petrographic description
SIST EN 932-3:2022

This document specifies a basic procedure for the identification of the petrographic type of natural aggregates. It applies for usual requirements for the procedure and terminology for simplified petrographic description. Precise petrographic identification, of technical mineralogy and petrography for civil engineering or specific end uses, requires further examination and is therefore excluded from the scope of this document.
NOTE 1 In principle, a qualified geologist (petrographer), with experience of materials used in civil engineering and aware of the composition of the deposit, has sufficient skills to sample and name the rock.
NOTE 2 For precise petrographic identification and technical requirements for specific applications, a non-exhaustive list of reference literature is given in the Bibliography.
This document applies only to natural aggregates. It is used to describe rocks and sediments. It does not apply to the description and identification of manufactured or recycled aggregates.

Tests for mechanical and physical properties of aggregates - Part 6: Determination of particle density and water absorption
SIST EN 1097-6:2022

This document specifies the reference methods used for type testing and in case of dispute, for the determination of particle density and water absorption of normal weight and lightweight aggregates. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. For convenience, some of these other methods are also described in this document.
The reference methods for normal weight aggregates are:
-   a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for railway ballast which uses Annex B);
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve (Clause 8);
-   a pyknometer method for aggregate particles passing the 4 mm sieve and retained on the 0,063 mm sieve (Clause 9).
In Clauses 7, 8 and 9, three different particle densities (oven-dried particle density, saturated and surface-dried particle density and apparent particle density) and water absorption are determined after a soaking period of 24 h. In Annex B, the oven-dried particle density is determined after soaking in water to constant mass.
For aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve, the wire basket method in Clause 7 can be used as an alternative to the pyknometer method in Clause 8.
NOTE 1   The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve.
NOTE 2   The pyknometer method described in Clause 8 can be used as an alternative for aggregates passing the 4 mm sieve and retained on the 2 mm sieve.
The reference methods for lightweight aggregates are:
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve (Annex C). Three different particle densities (oven-dried; saturated and surface-dried; apparent) and water absorption are determined after pre-drying and a soaking period of 24 h;
-   a method, using a Büchner funnel, for aggregate particles passing the 4 mm sieve (Annex D). The three particle densities and water absorption are determined using a vacuum in the range of 50 mbar to 100 mbar for at least five minutes.
Three other methods for normal weight aggregates can be used to determine the pre-dried particle density, as specified in normative Annexes A and H:
-   a wire basket method for aggregate particles passing the 63 mm sieve and retained on the 31,5 mm sieve (A.3);
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 0,063 mm sieve (A.4);
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve, including the 0/0,063 mm size fraction (Annex H).
NOTE 3   If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the pre-dried particle density method as defined in Annex A.
The quick method in normative Annex E can be used in factory production control to determine the apparent particle density of lightweight aggregates.
The method in informative Annex F can be used to determine the particle density and water absorption of aggregate particles passing the 4 mm sieve.
Data on the density of water at various temperatures is specified in normative Annex G.
Guidance on the significance and use of the various density and water absorption parameters is given in informative Annex I.
Precision data are presented in informative Annex J.
