Method and material for repairing of cracks in pavement and other surfaces

Abstract

The present invention relates to a method of repairing cracks and holes in pavement surfaces. This method involves filling a crack or hole in a paved surface with a flexible crack filler mix until the mix fills up the site and overlaps the edges of the aperture to a predetermined amount. Thereafter, the method includes the step of applying a zig-zag shaped mesh tape on top of the filled crack. The extra layer of a crack filler mix gets applied on top the zig-zag shaped mesh tape. Also disclosed is a material for repairing a crack in a paved surface.

1 . A method of repairing a crack in a pavement surface comprising the steps of:
 cleaning the crack of debris;   filling the crack with first portion of “crack filler” material that is allowed to harden to a solid state;   applying an additional portion of “crack filler” material to the sides of said opening;   applying a zigzag shaped tape over the filled crack and side portion of the filler material; the zigzag shaped tape being formed from loosely connected mesh segments that will follow the natural line of the crack;   applying a second portion of “crack filler” material over the laid zigzag shaped tape and for a distance beyond side edges of said tape; where the said distance is at least 1/32 inch; wherein said hardened “crack filler” material remains reasonably flexible and stretchable under temperatures between −45 C and +60 C. This allows and facilitates contraction and expansion between 0.3% and 8% of total width of said crack

         3 . A method of repairing a crack in a pavement surfaces recited in  claim 1 , wherein the said “crack filler” material is a petroleum emulsion 
     
     
         4 . A method of repairing a crack in a pavement surfaces recited in  claim 1 , wherein the said “crack filler” material is a polyepoxide thermosetting polymer 
     
     
         5 . A method of repairing a crack in a pavement surfaces recited in  claim 1 , wherein the said “crack filler” material is a hot-melt material, such as a liquefied rubber based compound as used by most driveway repair contracting companies. 
     
     
         6 . A method of repairing a crack in a pavement surfaces recited in  claim 1 , wherein the said “crack filler” material of said first portion is different type from said “crack filler” material of said second portion 
     
     
         7 . A method of repairing a crack in a pavement surfaces recited in  claim 1 , wherein the additional portion of said “crack filler” material is different type from said “crack filler” material of said first portion 
     
     
         8 . A material for crack repairs comprising a plurality of mesh segments connected in a chain by connectors; wherein said segments are in the same plane; wherein said connectors allow at least 10 degree rotation of said segments in the same plane against each other; wherein said mesh sizes are between 5×5 and 30×30 of Tyler scale, said mesh is made out of a vinyl coated fiberglass wire; said segments have minimum length of ⅙ in. and maximum length of 5 in.; said segments have a rectangular shape; said connectors are formed by stitching; said wire has gage from BWG31 to BWG38
