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.
Claims9
A method of repairing openings, including cracks, apertures and small potholes in a site in a roadway including the steps of:
- (A) supplying the site with a first material to fill the opening defined by said site and to soften the portion of the roadway adjacent the opening, said first material being comprised substantially of petroleum emulsion;
- (B) selecting as a second material an absorbent, highly porous, spreadable bulk material, from the group of organic, vegetatively-derived substances consisting of mulched leaves, mulched fruit, grass trimmings and garden trimmings, tree bark mulch, tree mulch, mulched wood, hay, sawdust;
- (C) following the supplying step, applying said second material as a cover blotter material to the site covering substantially the entirety of the first material such that said cover blotter performs a blotting function in that it both adsorbs and absorbs a continuous phase of said first material forming a suspended mass in said first material;
- and
- (D) compressing said second material into said first material until said second material permanently coagulates into said first material to produce a repaired road surface.
