Thermoplastic pothole repair material and method

Abstract

Disclosed is a thermoplastic material and method for repairing damaged asphaltic surfaces by filling “potholes” or damaged regions with thermoplastic fill that is placed in the damaged region of an asphaltic surface, heated to melt the fill in the damaged region and when sufficiently filled a thermoplastic color matched upper patch sheet is laid thereon and heated completing the asphaltic surface.

1 . A pothole filling material comprising a thermoplastic, wherein said thermoplastic is comprised of alkyd/polyamide or polyamide/ester modified gum. 
     
     
         2 . The pothole material of  claim 1 , wherein said thermoplastic fills and thereby repairs potholes in asphaltic surfaces. 
     
     
         3 . The pothole material of  claim 2 , wherein said thermoplastic is a color matching preformed thermoplastic patch sheet that covers said potholes. 
     
     
         4 . The pothole material of  claim 1 , wherein said thermoplastic is provided in an aggregate, granular or pellet form and applied in layers in said pothole. 
     
     
         5 . The pothole material of  claim 4 , wherein said thermoplastic is heated within said pothole to a molten state such that said layers are combined by melting into a single thermoplastic filling compound to complete pothole reparation. 
     
     
         6 . The pothole material of  claim 5 , wherein said molten state is achieved at a temperature greater than 300° Fahrenheit. 
     
     
         7 . The pothole material of  claim 6 , wherein said thermoplastic in said molten state flows into cracks, crevices and fissures in the asphaltic surfaces thereby providing an improved bond between the surrounding bitumen and said potholes. 
     
     
         8 . The pothole material of  claim 4 , wherein said preformed thermoplastic patch sheet is marked, cut and sized to extend over said pothole and heated sufficiently to melt said preformed thermoplastic patch sheet in order to combine said asphaltic surface with said pothole for optimized repair. 
     
     
         9 . The pothole material of  claim 4 , wherein said preformed thermoplastic patch sheet is color matched to any asphaltic road surface. 
     
     
         10 . The pothole material of  claim 4 , wherein said preformed thermoplastic patch sheet cracks and moves with said asphaltic road surface. 
     
     
         11 . The pothole material of  claim 1 , wherein said thermoplastic comprises from zero up to 100% recycled materials. 
     
     
         12 . A method of applying a pothole material comprising a thermoplastic, wherein said thermoplastic is comprised of alkyd/polyamide or polyamide/ester modified gum. 
     
     
         13 . The method of applying the pothole material of  claim 12 , wherein said thermoplastic wherein said thermoplastic fills and thereby repairs potholes in asphaltic surfaces. 
     
     
         14 . The method of applying the pothole material of  claim 13 , wherein applying said thermoplastic is a color matching preformed thermoplastic patch sheet covering potholes. 
     
     
         15 . The method of applying the pothole material of  claim 13 , wherein said thermoplastic is supplied in an aggregate, granular or pellet form and applied in layers in said pothole. 
     
     
         16 . The method of applying the pothole material of  claim 13 , wherein heating said thermoplastic within said pothole to a molten state provides for melting said layers together into a continuous thermoplastic repair. 
     
     
         17 . The method of applying the pothole material of  claim 16 , wherein heating said thermoplastic into said molten state is achieved at a temperature greater than  300  ° F. 
     
     
         18 . The method of applying the pothole material of  claim 17 , wherein heating said thermoplastic into said molten state allows for flowing said thermoplastic flow into cracks, crevices and fissures in the asphaltic surfaces thereby providing an improved bond with the surrounding bitumen. 
     
     
         19 . The method of applying the pothole material of  claim 16 , wherein preparation includes marking, cutting and sizing of said preformed thermoplastic patch sheet by extending said patch sheet over said pothole and heating sufficiently such that melting said preformed thermoplastic patch sheet together with said asphaltic surface and/or to said pothole, is achieved. 
     
     
         20 . The method of applying the pothole material of  claim 16 , wherein color matching blends said preformed thermoplastic patch sheet with any asphaltic road surface. 
     
     
         21 . The method of applying the pothole material of  claim 16 , wherein bonding of said preformed thermoplastic patch sheet with said pothole and said asphaltic road surface allows said preformed thermoplastic patch sheet to crack and move with said asphaltic road surface. 
     
     
         22 . The method of applying the pothole material of  claim 13 , wherein filling said pothole with said thermoplastic uses zero to up to  100 % recycled materials.
