Abstract (en)
[origin: US2012321382A1] The present invention provides a surface covering for enabling a surface, e.g. of the uneven, muddy, marshy, or sandy ground type, to be crossed by a vehicle, said surface covering including a double-ply textile core having two covered faces, each covered with at least one polymer layer, and a plurality of through tubular pockets extending substantially transversely through the thickness of the core between the two layers, and enabling respective stiffener bars to be inserted into each tubular pocket so as to make it possible, in particular, to increase the drivability and the load-bearing capacity of the surface when the surface covering is positioned on said surface.
