ABSTRACT:
A method of repairing cracks and apertures in a roadway, including the step of filling the crack or aperture with petroleum emulsion and overlapping the crack or aperture with the emulsion to preferably up to one inch or greater beyond the edge of the aperture on each side; applying a layer of an organic, cover blotter material and mounding said cover blotter material to cover substantially the entirety of said petroleum emulsion layer. The emulsion penetrates and softens the pavement surrounding the site. When the emulsion cures, it coagulates with the cover blotter material. The roadway is reopened to allow traffic to pass over the site to further compact and smooth out the roadway repaired surface to eventually form a pliable smooth patch.
