<p>A surfacing material comprises a mixture made up of: re-cycled rubber in the form of granules having a size in the range dust to 8 mm; or an ethylene propylene diene ternomer in the form of granules having a size in the range dust to 5 mm; aggregate, such as stone, granite, glass or sand, in the form of granules having a particle size in the range dust to at least 15 mm and, a urethane pre-polymer. The surfacing material can include a colorant or an aggregate of a pre-selected colour so as to provide an entire coloured surface or, in combination with a surfacing material of otherwise similar type which includes either no colorant or aggregate of a pre-selected colour or a colourant or aggregate of different colour, a surface having areas of different colour but of similar resilience and/or wearing characteristics. Thus it is possible to provide a surface material fabrication comprising a layer of the surfacing material deposited on a geotextile membrane serving to provide an impervious backing. Typically the layer serves to provide a generally porous volume above the impervious backing. Also, there can be provided a discrete load bearing structure having a surface bearing the surface material fabrication as aforesaid. Typically the layer of surfacing material is adapted to provide a porous body through which liquid deposited on the surface can percolate to a pre-determined level and thereafter passes through the material to one or more recovery locations for the liquid.</p> |
