A fill (34) is then placed within the pothole (12) atop the liner (18). The patch is completed by provision of an asphaltic, water-impervious, substantially non-stretch top mat (20) which is applied over the fill (34) and engaging and adhering to the liner (18) and adjacent portions (16) of the roadway (10).
