Benefits of technology
The present invention is a method for sealing cracks in pavement surfaces and roadways using a zigzag shaped mesh tape. This method improves sealing properties by using the zig-zag shaped mesh tape, which can follow the shape of the pavement cracking and is made of multiple mesh elements connected to each other. The zig-zag shaped mesh tape can also have heat-melt adhesive applied to the bottom side, which can be activated when a heat gun is applied on top of the tape. This method is cost-effective, simple, easy-to-use, and durable.
Problems solved by technology
However, such crack repair method is considered a temporary repair since progressive maintenance must be applied because of continued crack enlargement under changing environmental conditions, including temperature and moisture fluctuations.
Repaired cracks continue to expand since current repair methods do not address and alleviate the stresses that cause crack formation and movement.
However, the fiberglass sheet, while presenting a solid, hard surface, is also susceptible to tears and cracks caused by movement and / or enlargement of the underlying repaired crack.
While the described prior crack repair methods significantly lengthens the time between maintenance to a repaired crack, these methods still experience failures due to and caused by crack reformation.
Another very significant problem is related to a crack shape.
The crack shape does not normally allow the application of straight, uniformly shaped, strips of overlaying material.
Custom shaped pieces of material, to follow the crack must be individually cut which makes this method somewhat haphazard and time consuming.

Embodiment Construction
[0022]FIG. 4 depicts a crack 406 in a pavement 401.The crack 406 is about two inches in depth and ¼ inch wide. The method of the present invention is preferably used with cracks of such a depth, in various types of bituminous pavements, or cement concrete pavements. However, the scope of the invention is not confined to repair sites of such a depth and width.
[0023]In accordance with the method of the present invention, the crack 406 in the pavement is filled with a flexible crack filler. The term “crack filler” as used herein shall include petroleum emulsions, asphalt emulsions or modifications to such emulsion, acrylic emulsions,rubberized asphalt and epoxy mixtures, heat melt fillers.
[0024]A suitable flexible crack filler that can be used in conjunction with this invention is a product sold under the trademark “Latex-ite Blacktop Crack Filler” by Dalton Enterprises, Inc. of Cheshire, Conn. It is preferred that the crack filler used in the process of the present invention has a vis...

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.
Description
CLAIM OF PRIORITY[0001]This application claims priority under 35 USC Section 119(a) from U.S. Provisional Application No. 61 / 356,363 filed Jun. 18, 2010. The above mentioned application is hereby incorporated by reference in their entirety.BACKGROUND OF THE INVENTION[0002]The present invention is directed to a method and system for repairing cracks or holes in a paved surface.[0003]Various methods for repairing cracks and holes in paved surfaces, concrete or asphalt roadways, driveways and recreational surfaces, such as tennis courts, outdoor basketball courts, volleyball courts and running tracks generally involve cleaning the crack of loose debris and then filling the crack with a crack filler material that hardens to a solid state, forming a smooth surface with the surrounding pavement surface. This is more economical than re-paving the entire section of pavement which may contain only one or a few cracks.[0004]However, such crack repair method is considered a temporary repair si...
