Bituminous mixtures - Test methods - Part 46: Low temperature cracking and properties by uniaxial tension tests

This document specifies uniaxial tension tests for characterizing the resistance of an asphalt mixture against low temperature cracking. The results of the uniaxial tension tests can be used to evaluate the following:
-   tensile strength at a specified temperature, using the uniaxial tension stress test (UTST);
-   minimum temperature that the asphalt can resist before failure, using the thermal stress restrained specimen test (TSRST);
-   tensile strength reserve at a specified temperature (using a combination of TSRST and UTST);
-   relaxation time, using the relaxation test (RT);
-   creep curve to back calculate rheological parameters, using the tensile creep tests (TCT);
-   fatigue resistance at low temperatures due to the combination of cryogenic and mechanical loads, using the uniaxial cyclic tension stress tests (UCTST).

Asphalt - Prüfverfahren - Teil 46: Widerstand gegen Kälterisse und Tieftemperaturverhalten bei einachsigen Zugversuchen

Dieses Dokument legt einachsige Zugversuche zur Bestimmung des Widerstandes eines Asphaltgemischs gegen Kälterisse fest. Die Ergebnisse der einachsigen Zugversuche können zur Beurteilung folgender Eigen¬schaften verwendet werden:
-   Zugspannung bei einer festgelegten Temperatur unter Anwendung des direkten (einachsigen) Zugversuchs (en: Uniaxial Tension Stress Test, UTST);
-   Tiefsttemperatur, bis zu der der Asphalt dem Ausfall widerstehen kann, unter Anwendung des Abkühlversuchs (en: Thermal Stress Restrained Specimen Test, TSRST);
-   Zugfestigkeitsreserve bei einer festgelegten Temperatur (unter Anwendung einer Kombination aus TSRST und UTST);
-   Relaxationszeit unter Anwendung des Relaxationsversuchs (en: Relaxation Test, RT);
-   Kriechkurve, um durch Zugkriechversuche (en: Tensile Creep Test, TCT) auf rheologische Parameter zurückrechnen zu können; und
-   Ermüdungsverhalten bei niedrigen Temperaturen aufgrund der Kombination kryogener und mechanischer Beanspruchungen unter Anwendung von einachsigen zyklischen Zugversuchen (en: Uniaxial Cyclic Tension Stress Test, UCTST).

Mélanges bitumineux - Méthodes d'essai - Partie 46 : Fissuration et propriétés à basse température par des essais de traction uniaxiale

Ce document spécifie les essais de traction uniaxiale permettant de caractériser la résistance à la fissuration à basse température d'un mélange d'enrobé. Les résultats des essais de traction uniaxiale peuvent servir aux évaluations suivantes :
- la résistance à la traction à une température spécifiée en procédant à un essai de contrainte de traction uniaxiale (UTST) ;
- la température minimale à laquelle peut résister l'enrobé avant sa rupture en procédant à un essai sur éprouvette en retrait empêché sous contrainte thermique (TSRST) ;
- la réserve de résistance à la traction à une température spécifiée (en combinant TSRST et UTST) ;
- du temps de relaxation en procédant à l'essai de relaxation (RT) ;
- la courbe de fluage afin de recalculer les paramètres rhéologiques en procédant à des essais de fluage (TCT) ;
- la résistance à la fatigue aux basses températures due à la combinaison de charges cryogéniques et mécaniques en procédant à des essais de contrainte de traction cyclique uniaxiale (UCTST).
