Bituminous mixtures - Test methods for hot mix asphalt - Part 25: Cyclic compression test

This document describes two test methods (A and B) for determining the resistance of bituminous mixtures to permanent deformation.
Test method A describes the method for determining the creep characteristics of bituminous mixtures by means of an uniaxial cyclic compression test with some confinement present. In this test a cylindrical specimen is subjected to a cyclic axial stress. To achieve a certain confinement, the diameter of the loading platen is taken smaller than that of the sample.
NOTE   Confinement of the sample is necessary to predict realistic rutting behaviour, especially for gap-graded mixes with a large stone fraction.
Test method B describes the method for determining the creep characteristics of bituminous mixtures by means of the triaxial cyclic compression test. In this test a cylindrical specimen is subjected to a confining stress and a cyclic axial stress. This test is most often used for the purpose of evaluation and development of new types of mixtures.
This document applies to specimens prepared in the laboratory or cored from the road. The maximum size of the aggregates is 32 mm.
This European Standard applies to specimens prepared in the laboratory or cored from the road. The maximum size of the aggregates is 32 mm.

Asphalt - Prüfverfahren für Heißasphalt - Teil 25: Druckschwellversuch

Diese Europäische Norm beschreibt zwei Prüfverfahren (A und B) zur Bestimmung der Beständigkeit von
Asphalt gegen bleibende Verformung.
Das Prüfverfahren A beschreibt das Verfahren zur Bestimmung der Kriecheigenschaften von Asphalt mit Hilfe
eines einaxialen Druckschwellversuchs mit begrenzter Behinderung der Querdehnung. Bei dieser Prüfung
wird ein zylindrischer Probekörper einer zyklischen Axialbelastung ausgesetzt. Um eine bestimmte Behinde-
rung der Querdehnung zu erreichen, wird für die Lastplatte ein Durchmesser gewählt, der kleiner ist als der
des Probekörpers.
ANMERKUNG Die Behinderung der Querdehnung des Probekörpers ist erforderlich, um das tatsächliche Spurrinnen-
bildungsverhalten, besonders für Mischgüter mit Ausfallkörnung mit einem großen Splitt-Anteil, vorherzusagen.
Das Prüfverfahren B beschreibt das Verfahren zur Bestimmung der Kriecheigenschaften von Asphalt mit Hilfe
des triaxialen Druckschwellversuchs. Bei dieser Prüfung wird ein zylindrischer Probekörper einem Druck zur
Behinderung der Querdehnung (Stützdruck) und einer zyklischen Axialbelastung ausgesetzt. Die Prüfung wird
für die Bewertung und die Entwicklung neuer Arten von Mischgütern verwendet.
Diese Europäische Norm gilt für Probekörper, die entweder im Labor hergestellt oder durch
Bohrkernentnahme aus der Straße gewonnen wurden. Die maximale Korngröße beträgt 32 mm.

Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné a chaud - Partie 25 : Essai de compression cyclique

La présente Norme européenne décrit deux méthodes d'essai (A et B) destinées à déterminer la résistance à la déformation permanente de mélanges bitumineux.
La méthode d'essai A décrit le mode opératoire pour déterminer les caractéristiques de fluage de mélanges bitumineux au moyen d'un essai de compression cyclique uniaxial sous un certain confinement. Lors de cet essai, une éprouvette cylindrique est soumise à une contrainte axiale cyclique. Pour obtenir un certain confinement, le diamètre du piston de chargement est pris inférieur à celui de l'éprouvette.
NOTE   Le confinement de l'éprouvette est nécessaire pour prévoir un comportement à l'orniérage réaliste, en particulier pour les mélanges à granulométrie discontinue avec une fraction importante de gravillons.
La méthode d'essai B décrit le mode opératoire pour déterminer les caractéristiques de fluage de mélanges bitumineux au moyen d'un essai de compression cyclique triaxial. Lors de cet essai, une éprouvette cylindrique est soumise à une contrainte de confinement et à une contrainte axiale cyclique. Cet essai est le plus souvent utilisé dans le but d'évaluer et de développer de nouveaux types de mélanges.
La présente Norme européenne s'applique aux éprouvettes préparées en laboratoire ou extraites de la chaussée. La dimension maximale des granulats est de 32 mm.

Introduction
This European Standard contains two test methods to determine the resistance to permanent deformation of a
bituminous mixture by cyclic compression tests with confinement. The tests make it possible to rank various
mixes or to check on the acceptability of a given mix. They do not allow making a quantitative prediction of
rutting in the field to be made. The choice for confinement was made in order to obtain realistic test results for
gap-graded mixes.
1 Scope
This European Standard describes two test methods (A and B) for determining the resistance of bituminous
mixtures to permanent deformation.
Test method A describes the method for determining the creep characteristics of bituminous mixtures by
means of an uniaxial cyclic compression test with some confinement present. In this test a cylindrical
specimen is subjected to a cyclic axial stress. To achieve a certain confinement, the diameter of the loading
platen is taken smaller than that of the sample.
NOTE 1 Confinement of the sample is necessary to predict realistic rutting behaviour, especially for gap-graded mixes with a large
stone fraction.
Test method B describes the method for determining the creep characteristics of bituminous mixtures by
means of the triaxial cyclic compression test. In this test a cylindrical specimen is subjected to a confining
stress and a cyclic axial stress. This test is most often used for the purpose of evaluation and development of
new types of mixtures.
This European Standard applies to specimens prepared in the laboratory or cored from the road. The
maximum size of the aggregates is 32 mm.
NOTE 2 For purposes of compliance with EN 13108, the test conditions are given in prEN 13108-20.
