Method and system for repairing cracks in a paved surface
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, wherein the second layer hardens to form a rigid mat above the first layer; 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 further comprising:
cleaning the crack and the paved surface prior to said applying.
7. The method according to claim 1 further comprising:
filling the crack with a binder or cement material prior to said applying.
8. 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, wherein the second layer forms a rigid mat; 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.
9. The system according to claim 8 , wherein the watertight tape has an adhesive surface.
10. The system according to claim 9 , wherein the watertight tape has a surface opposite the adhesive surface comprising a fabric backing.
11. The system according to claim 8 , wherein the watertight tape is flexible at temperatures as low as about −70° F. to more than 200° F.
12. The system according to claim 8 , wherein the watertight tape is pliable.
13. The system according to claim 8 , wherein the watertight tape has a thickness of about 1 mm.
14. The system according to claim 8 , wherein said adhering is carried out with a liquid acrylic.
