  • Patent number: 5846890
    Abstract: A temporary surface covering to allow or facilitate the circulation of vehicles on sandy or swampy soils. The surface covering is formed of a woven structure formed from weft threads (N.sup.o 1 to 26) of the monofilament type disposed along a single layer and warp threads (N.sup.o 1 to 10), also disposed along a single layer. The weave of the woven structure is such that each warp thread is interlaced with the weft thread preferably and approximately along half the intersections of the rows and columns of the weave so as to obtain, for each warp thread, at least one tight single weave zone (A) followed by a loose thread zone (B). The alternation of the various zones provokes retightenings of the weft threads creating a large relief (S1, S2, C1, C2) of the fabric embodied.
