Abstract (en)

1. Composite structure for roadways and surfaced areas, based on bituminous mixtures comprising various superposed courses of materials bonded with a bituminous binder from a base course (6) in contact either with the foundation or with the roadway or area to be surfaced and a surfacing course (2), the said structure being characterised in that at least its base course (6) consists of a bituminous material capable of withstanding an alternating flexure fatigue test lasting for 10**6 cycles while being subjected to relative deformations greater than 1,5 10**-4 , and in that the thickness of the said base course is restricted to at least a part of the zone subjected to tensile stresses (5) under the effect of a single moment acting on the composite structure.

Abstract (fr)

L'invention concerne une structure composite pour chaussées et aires de roulement. Ladite structure est caractêrisée en ce que la partie inférieure au moins de cette structure composite est constituée d'un matériau à grande capacité d'aliongement sous efforts répétés, et en ce que l'épaisseur de ladite partie inférieure est limitée à au moins une partie de la zone soumise à des contraintes de traction. Application: revêtement des routes.
