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.

What is claimed is: 1. 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. 2. A stabilizing body as claimed in claim 1, in which the cells, forming the multi-cell configuration defined by the planar body, each have a base wall that at least partially blocks the cell on the operative bottom side of the planar body. 3. A stabilizing body as claimed in claim 2, in which each base wall defines at least one projecting formation that projects operatively upwardly therefrom towards the operative top side of the planar body, each such projecting formation comprising a continuously curved formation that provides its base wall with a continuously curved profile when viewed in section. 4. A stabilizing body as claimed in claim 3, in which the operative height of the projecting formation that projects from the base wall of a cell is between 10% and 50% of the operative depth of the cell. 5. A stabilizing body as claimed in claim 1, in which the multi-cell configuration defined by the planar body is an open-cell configuration in which the cells extend through the body from the operative top side thereof to the operative bottom side thereof. 6. A stabilizing body as claimed in claim 3, in which each base wall defines a plurality of projecting formations that project operatively upwardly thereform and that are arranged to define a plurality of contained spaces within the cell in which they are defined. 7. A stabilizing body as claimed in claim 6, in which each cell having a plurality of projecting formations projecting operatively upwardly from the base wall thereof defines an egg-crate configuration. 8. A stabilizing body as claimed in claim 6, in which the operative height of each projecting formation that projects from the base wall of a cell is between 10% and 50% of the operative depth of the cell. 9. A stabilizing body as claimed in claim 2, in which each base wall defines an opening therein that can serve as a drainage passage for a liquid to drain from the associated cell. 10. A stabilizing body as claimed in claim 1, in which the side walls forming the cells defined by the planar body extend substantially perpendicularly to the general plane of the planar body. 11. A stabilizing body as claimed in claim 1, in which the side walls forming the cells are configured to define cells that taper from the operative top face side of the planar body to the operative bottom face side of the planar body. 12. A stabilizing body as claimed in claim 1, in which the planar body defines either one of a square and a rectangular outer perimeter profile, rendering similar bodies positionable adjacent one another to form an extended substantially continuous planar structure. 13. A stabilizing body as claim in claim 1, in which the planar body defines complementary engagement formations at locations along the outer perimeter thereof that permit inter-engagement of similar bodies when placed adjacent one another, to form an extended substantially continuous planar structure. 14. A stabilizing body as claimed in claim 1, which is formed of a synthetic plastics material. 15. A stabilizing body as claimed in claim 1, in which the planar body comprises a square body having outer dimensions of up to 1. 2횞1.2 meters. 16. A stabilizing body as claimed in claim 1, in which the planar body has a thickness between the top side thereof and the bottom side thereof between 10 mm and 50 mm.
