Method and system for repairing cracks in a paved surface

Abstract

The present invention relates to a method of repairing a crack in a paved surface. This method involves applying a watertight tape over a crack in a paved surface to cover the crack and form a first layer. The tape is applied with an adhesive. The first layer is contacted with a first liquid acrylic adhesive. The first layer is covered with a polyester fabric to form a second layer that adheres to the first layer. The polyester fabric is impregnated with a second liquid acrylic adhesive. A fiberglass sheet is adhered to at least a portion of the second layer and to the paved surface beyond edges of the second layer to form a transition layer over the edges. Also disclosed is a system for repairing a crack in a paved surface.

1 . A method of repairing a crack in a paved surface, said method comprising:
 applying a watertight tape over a crack in a paved surface to cover the crack and form a first layer, wherein the tape is applied with an adhesive;   contacting the first layer with a first liquid acrylic adhesive;   covering the first layer with a polyester fabric to form a second layer that adheres to the first layer;   impregnating the polyester fabric with a second liquid acrylic adhesive; and   adhering a fiberglass sheet to at least a portion of the second layer and to the paved surface beyond edges of the second layer to form a transition layer over the edges.   
   
   
       2 . The method according to  claim 1 , wherein the watertight tape is flexible at temperatures as low as about −70° F. to more than 200° F. 
   
   
       3 . The method according to  claim 1 , wherein the watertight tape is pliable. 
   
   
       4 . The method according to  claim 1 , wherein the watertight tape has a thickness of about 1 mm. 
   
   
       5 . The method according to  claim 1 , wherein the watertight tape has a fabric backing. 
   
   
       6 . The method according to  claim 1 , wherein the second layer hardens to form a rigid mat. 
   
   
       7 . The method according to  claim 1  further comprising:
 cleaning the crack and the paved surface prior to said applying.   
   
   
       8 . The method according to  claim 1  further comprising:
 filling the crack with a binder or cement material prior to said applying.   
   
   
       9 . A system for repairing a crack in a paved surface, said system comprising:
 a watertight tape capable of forming a first layer over a crack in a paved surface;   a polyester fabric impregnated with a liquid acrylic capable of forming a second layer that adheres to and covers the first layer; and   a fiberglass sheet capable of adhering to at least a portion of the second layer and to the paved surface beyond edges of the second layer to form a transition over the edges.   
   
   
       10 . The system according to  claim 9 , wherein the watertight tape has an adhesive surface. 
   
   
       11 . The system according to  claim 10 , wherein the watertight tape has a surface opposite the adhesive surface comprising a fabric backing. 
   
   
       12 . The system according to  claim 9 , wherein the watertight tape is flexible at temperatures as low as about −70° F. to more than 200° F. 
   
   
       13 . The system according to  claim 9 , wherein the watertight tape is pliable. 
   
   
       14 . The system according to  claim 9 , wherein the watertight tape has a thickness of about 1 mm. 
   
   
       15 . The system according to  claim 9 , wherein the second layer hardens to form a rigid mat. 
   
   
       16 . The system according to  claim 9 , wherein said adhering is carried out with a liquid acrylic.
