The invention relates to the use of stabilizing body in the construction of roads. The stabilizing body comprises a substantially rigid, planar body (20) that can be inter-engaged with other similar bodies in a configuration in which an extended, substantially planar stabilizing structure can be formed. Each stabilizing body defines a multi-cellular configuration with cells (26) defined by side walls extending from the operative top side of the body towards the operative bottom side thereof. The side walls (28) defining the cells have projecting formations (30) projecting therefrom into the cells. In use, the wearing course of a road is formed within and above a stabilizing structure formed above the base of the road, with the asphalt composition used filling the cells and being anchored to the stabilizing bodies via the projecting formations, thus forming a wearing course resistant to various different known of road failure.
A stabilizing body for use in the construction of asphalt roads, which comprises a substantially rigid, planar body defining a multi-cell configuration between spaced operative top and bottom sides of the planar body, and in which the cells are defined by surrounding side walls extending from the operative top side of the body towards the operative bottom side of the body and the side walls of each cell have a plurality of projecting, continuously curved, rib formations that project therefrom, without sharp corners that can induce reflective cracks, into the space defined by the cell and that extend substantially parallel to the general plane of the body, the rib formations, in use of stabilizing body, serving to anchor an asphalt composition that is received in the cells for forming a road surface within the cells.
