Abstract (en)
[origin: WO9425676A1] Element assembly for paving roads and the like, developing a filtering effect for flowing fluids and having at least two superimposed coatings (1, 2, 3 ...) in the direction of flow from the upper entry side to the lower exit side, in which the upper layer on the entry side is substantially thinner than each of the underlying layers (2, 3 ...) and the free through-flow sections (a) of the layer on the entry side are smaller than the free through-flow sections (b, c ...) of each of the underlying layers (2, 3 ...), whereby the dimensions of the free through-flow sections (a, b, c ...) increase in the successive layers in the direction of flow.
