A method of repairing asphalt or concrete surfaces such as roads and parking lots which have developed pot holes therein. The hole is cleaned of loose debris, lined with a water barrier sheet, provided with a reinforcing mesh, and filled with hot asphalt mix. The asphalt mix is compacted by a roller which has been chilled by exposure to a cryogenic substance, such as liquid nitrogen. Alternatively, the cryogenic substance directly contacts the asphalt mix. Preferably, the reinforcing mesh is further reinforced by flattened rods woven through the mesh or alternatively, laid thereon, with the rods oriented at angles of approximately forty-five degrees to linear structural members of the mesh. The water barrier, reinforcing mesh, and reinforcing rods are preferably formed from recycled plastic materials.
