Abstract: A preformed surfacing for a pavement is in the form of a sheet of flexible material containing cavities open to its upper surface and interconnected by ducts beneath the surface so that when laid down on a prepared subsurface having a drainage slope, water falling on the surfacing can drain away through the cavities and ducts. The sheet can be fixed to the subsurface by anchors bonded into cavities in the sheet.
