ABSTRACT:
An improved roadway patching system and method is provided for repairing potholes (12) or other damaged roadway areas. The patching system of the invention includes a lower asphaltic liner (18) which is adapted for placement within a pothole (12) or the like in closely conforming and adhering relationship with the inner contour (14) thereof in order to present a substantially water-impervious barrier. 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).
