Abstract(s)This paper presents some new and significant aspects of pre-failure deformation characteristics, particularly stress-strain properties at small strains, of crushed unbound granular materials used in pavement construction. The data was obtained from a series of precision cyclic triaxial tests performed at the Institute of Industrial Science, University of Tokyo, using stress paths and strain levels representatives of pavement field conditions. Based in this data, effects of stress state and strain level in Young’s modulus are discussed to some depth.
Cet article présente des aspects nouveaux et significatifs des caractéristiques des geomatériaux, en particulier les propriétés contraintedéformation en petites déformations des matériaux granulaires concassés non traités utilisés dans la construction routière. Les donnés ont été obtenus par des essais triaxiaux cycliques de précision réalisés à l’ "Institute of Industrial Science, University of Tokyo", en utilisant des chemins de contrainte et des niveaux de déformation représentatives dans les chaussées. Ces données ont permis de mettre en évidence les effets de l’état de contrainte et du niveau de déformation dans le Module d’Young.
