Lobjectif de ce travail consiste à caractériser expérimentalement le comportement en fatigue dun béton bitumineux renforcé à laide des grilles en fibre de verre (géo-grilles). Le travail est basé sur une campagne expérimentale de 38 essais de fatigue alternée en flexion en quatre points (4PB), respectivement : 18 essais sur des éprouvettes en béton bitumineux non-renforcée (NR) et 20 essais sur des éprouvettes en béton bitumineux renforcé (R) à laide de deux géo-grilles. Toutes les éprouvettes sont fabriquées en trois couches. Les essais sont réalisés à 10°C avec une fréquence de 25Hz, conformément à EN 12697-24, 2012. Cette étude a permis de montrer que la présence des géogrilles retarde la propagation des fissures et augmente la durée de vie en fatigue conventionnelle du béton bitumineux.
