A paving structure (11) of the type having an upper wear layer (12) and an underlying sub-base layer (15) of rigid insoluble hard particulate material forming voids for the collection of water permeating through the permeable surface where layer (12) has an intermediate reinforcing grid (16) located at an intermediate level of the sub-base layer (15) such that it is covered by an upper part of the sub-base layer (15U) which is of a thickness not less than 1 1/2 times the dimension of the largest particles in that part of the sub-base layer. A reinforcing grid (26) at the base of the sub-base layer between this and the sub grade (18) may also be provided.

L'invention concerne une structure de revêtement de sol (11) du type ayant une couche d'usure supérieure (12) et une couche de base sous-jacente (15) réalisée dans un matériau particulaire dur insoluble rigide formant des cavités destinées à recueillir l'eau s'infiltrant par la couche d'usure à surface perméable (12). Cette structure a une grille de renforcement intermédiaire (16) qui est située à un niveau intermédiaire de la couche de base sous-jacente (15) de telle manière qu'elle soit recouverte d'une partie supérieure de la sous-couche de base (15U) ayant une épaisseur minimale de 1 ? fois la dimension des plus grandes particules de cette partie de la couche de base sous-jacente. Il peut également y avoir une grille de renforcement (26) à la base de la couche de base sous-jacente entre cette dernière et le fond de forme (18).
