Bituminous mixtures - Test methods for hot mix asphalt - Part 46: Low Temperature Cracking and Properties by Uniaxial Tension Tests

Definition of a test method to determine the susceptibility of asphalt to crack at low temperature and the temperature at which such cracking is likely to occur

Asphalt - Prüfverfahren für Heißasphalt - Teil 46: Rissbildung und Eigenschaften bei niedrigen Temperaturen

Mélanges bitumineux - Essais pour enrobés à chaud - Partie 46: Fissuration et propriétés à basse température par des essais de traction uniaxiale

Le présent document (prEN 12697-46:2008) décrit 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 à l'évaluation de :
-   la résistance à la traction en fonction de la température 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 en fonction de la température (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 dans l'état de traction 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).
