System and Method For Repairing Damaged Portions of a Concrete Surface

Abstract

A method of repairing a damaged portion of a roadway comprises cutting around the damaged portion using a circular saw blade to form cut lines that include overcut portions and angled intersections. Using a grinder, or some other tool, a user removes the overcut portions and angled intersections formed by the cut lines to form a smooth and contiguous edge around the damaged portion. The damaged portion is filled a repair material, such as a polymer resin.

1 . A method of repairing a damaged portion of a roadway comprising:
 cutting around the damaged portion to form cut lines that include overcut portions;   removing roadway material from within an area defined by the cut lines to form a cutout;   removing the overcut portions from the roadway; and   filling the cutout with a repair material.   
     
     
         2 . The method of  claim 1 , wherein the step of cutting around the damaged portion comprises using a power saw with a circular blade. 
     
     
         3 . The method of  claim 1 , wherein the roadway is formed of concrete. 
     
     
         4 . The method of  claim 1 , wherein the roadway is formed of asphalt. 
     
     
         5 . The method of  claim 1 , wherein the step of removing the overcut portions comprises using a grinder. 
     
     
         6 . The method of  claim 1 , wherein the area defined by the cut lines is a polygon. 
     
     
         7 . The method of  claim 1 , wherein the repair material comprises a polymer resin. 
     
     
         8 . The method of  claim 1 , wherein removing the roadway material within the area defined by the cut lines comprises using a power tool. 
     
     
         9 . A method of repairing a damaged portion of a roadway comprising:
 cutting around the damaged portion to form cut lines that intersect at an angle to form a corner;   removing roadway material from within an area defined by the cut lines to form a cutout;   smoothing the corner formed by the cut lines; and   filling the cutout with a repair material.   
     
     
         10 . The method of  claim 9 , wherein the step of cutting around the damaged portion comprises using a power saw with a circular blade. 
     
     
         11 . The method of  claim 9 , wherein the roadway is formed of concrete. 
     
     
         12 . The method of  claim 9 , wherein the roadway is formed of asphalt. 
     
     
         13 . The method of  claim 9 , wherein the step of removing the corner comprises using a grinder. 
     
     
         14 . The method of  claim 9 , wherein the area defined by the cut lines is a polygon. 
     
     
         15 . The method of  claim 9 , wherein the repair material comprises a polymer resin. 
     
     
         16 . The method of  claim 9 , wherein the step of removing the roadway material within the area defined by the cut lines comprises using a power tool. 
     
     
         17 . The method of  claim 9 , wherein the angle formed by the cut lines is between eighty degrees and one hundred degrees. 
     
     
         18 . The method of  claim 17 , wherein the angle is about ninety degrees. 
     
     
         19 . A method of repairing a damaged portion of a concrete roadway, the damaged portion having a jagged edge comprising:
 smoothing the jagged edge of the damaged portion; and   filling the damaged portion with a repair material comprising a polymer resin.   
     
     
         20 . The method of  claim 19 , wherein the step of smoothing the jagged edge comprises using a grinder.
