Bituminous mixtures - Test methods - Part 10: Compactability
This European Standard describes three test methods for characterizing the compactability of a bituminous mix, by the relation between its density or void content and the compaction energy applied to it, using an impact (Marshall) compactor, gyratory compactor, or a vibratory compactor.
This European Standard applies to hot bituminous mixtures (both those prepared in laboratory and those resulting sampled from plant produced mixtures), with D not larger than 31,5 mm in accordance with EN 13043 for the impact and gyratory compactors, and 40 mm for the vibratory compactor. The results of the test method serve to supplement the results of mixture design.
Asphalt - Prüfverfahren für Heißasphalt - Teil 10: Verdichtbarkeit
Diese Europäische Norm beschreibt drei Prüfverfahren zur Kennzeichnung der Verdichtungsfähigkeit einer bitumenhaltigen Mischung, durch das Verhältnis zwischen seiner Dichte oder Luftporengehalts und der angewandten Verdichtungsenergie, bei dem ein Schlagverdichter (Marshall-Verdichter), ein Gyrator-Verdichter oder ein Vibrationsverdichter verwendet wird.
Diese Europäische Norm gilt für Mischungen aus Heißasphalt (die sowohl im Labor vorbereitet wurden als auch Proben aus maschinenhergestellten Mischungen), wobei D nicht größer ist als 31,5 mm in Übereinstimmung mit EN 13043 für die Schlagverdichter und Gyrator-Verdichtertypen, und 40 mm für den Vibrator-Verdichter. Die Ergebnisse des Prüfverfahrens dienen zur Ergänzung der Ergebnisse aus der Mischgestaltung.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 10 : Compactabilité
La présente Norme européenne décrit trois méthodes d'essai permettant de caractériser la compactabilité d'un enrobé par la relation entre sa masse volumique apparente ou son pourcentage de vides et l'énergie de compactage qui lui est appliquée à l'aide d'une machine de compactage par damage (Marshall), d'une presse à compactage giratoire ou d'un compacteur vibratoire.
La présente Norme européenne s'applique aux mélanges bitumineux à chaud confectionnés en laboratoire ou prélevés sur des mélanges produits en centrales dont la taille D, selon l'EN 13043, n'est pas supérieure à 31,5 mm pour le compactage par damage et le compactage giratoire, et à 40 mm pour le compactage par vibration. Les résultats de la méthode d'essai servent à compléter les résultats de l'épreuve de formulation.

EN 12697-10:2017 (E) 5 Note 1 to entry: High values of C and T will indicate a mixture for which high compaction energy is required to obtain a given void content decrease. 4 Principle The bituminous mixture is compacted at a prescribed temperature with varying compaction energies using one of three optional types of compaction methods: a) impact compaction b) gyratory compaction c) vibratory compaction. Two methods of monitoring the compactability can be applied: — Method 1: two or more specimen are compacted with different amounts of compaction energy and their densities are measured. — Method 2: one specimen is used and its increase in density during the compaction process is determined from its decrease in thickness. The following Table 1 defines the compaction type to use depending of the compactness of tracking method and gives the clause of test procedure. Table 1 — Compaction type
Procedure clause according to compaction method impact gyratory vibratory Compaction of specimens with varied compaction energy 6.1.1 n. a. 6.3 Measurement of specimen thickness during compaction 6.1.2 6.2 n. a. A graph is drawn of density (or voids content) against compaction energy. When the impact compaction is used, the compaction energy is characterized by the number of blows, when the gyratory compaction is used, by the number of gyrations and when the vibratory compactor is used, by the duration in seconds. A mathematical formula is derived from the experimental results, the parameters of which formula characterize the compactability of the bituminous mixture. 5 Apparatus 5.1 Impact compaction 5.1.1 Marshall compactor in accordance with EN 12697-30. 5.1.2 Measuring device for automatically recording the thickness of the specimen after each blow of compaction wit
