A frictional, in situ self-draining composite structure for runway and roadway structural docking and pathway surface. The composite structure has a solid base to which is bound a porous superstratum of aggregate and resinous binder. The composite structure is fabricated by applying a first mixture containing about two to about four parts by volume of aggregate particles of crushed rock, river gravel, crushed coral, coarse sand, slag, or crushed refractory material and one part by volume of a settable resinous binder to the base section and allowing it to set, and then by applying a second mixture containing about two to about four parts by volume of scoria and/or slag particles and one part by volume of a settable resinuous binder to the first porous layer. |
