Abstract
The use of energy dissipation has been extended for assessing the resistance to permanent deformation of bituminous mixtures. The method is found beneficial for accurately determining the end of the linear region from the curves of permanent strain versus number of loading cycles, where the strain rate is constant. An analysis procedure based upon a combined technique of strain rate and energy dissipation method is presented.
Résumé
La méthode de l'énergie de dissipation a été étendue pour mesurer la résistance à la déformation permanente des mélanges bitumineux. Cette méthode s'avère avantageuse pour définir précisément la position de la fin de la région linéaire des courbes de déformation relative au nombre des cycles de chargement. Une procédure analytique basée sur une technique combinant la vitesse de la déformation et la dissipation de l'énergie est présentée.
