Abstract

A method for repairing roadway and pathway defects utilizes a filling material and a primer. The method calls for applying the primer to an edge of the defect; pouring the filling material into the defect; and curing the filling material to form a patch that is even with the road.

Claims

1. A method for filling a pot hole in a road utilizing a filling material, a primer and a catalyst, the method comprising the steps of:

applying the primer to an edge of the pot hole;

pouring the filling material into the pot hole; and

curing the filling material to form a patch that is even with the road.

2. The method of claim 1 in which the primer is applied to the entire surface of the pot hole.

3. The method of claim 1 in which the step of applying the primer is preceded by a step of cleaning the pot hole.

4. The method of claim 1 in which the step of curing the filling material comprises spraying the surface of the filling material with the catalyst.

5. The method of claim 1 in which the pot hole is a defect near a manhole, and the pot hole is filled with a filling material and the primer.

6. A method of applying a filling material in the space around a manhole structure to prevent deterioration of a collar formed from concrete, the method comprising the steps of:

pouring the concrete into the space around the manhole structure to form the collar;

applying the filling material over the collar; and

curing the filling material to form a rigid support around the manhole structure which absorbs impacts produced when vehicles pass over the manhole structure.

7. The method of claim 6 in which the primer is applied to the entire surface of the wet concrete.

8. The method of claim 6 in which the step of applying the primer is preceded by a step of leveling the concrete.

9. The method of claim 6 in which the step of curing the filling material comprises spraying the surface of the filling material with the primer.

10. The method of claim 6 in which the step of curing the filling material comprises spraying the surface of the filling material with catalyst and then water.

11. A method for raising the level of a manhole structure and collar to the level of a resurfaced road utilizing a cover, a separator ring, and a filling material, the method comprising the steps of:

applying the cover on top of the manhole structure and the collar;

erecting protection of the manhole cover and ring from being covered with the asphalt;

pouring the asphalt over the road;

removing the protection from the manhole cover and ring;

positioning the separator ring around the lid;

applying the filling material over the manhole structure and the collar to form a secondary lid and surround each having a height equal to the resurfaced road; and

removing the separator ring from around the lid.

12. The method of claim 11 wherein a primer is applied to manhole cover and ring before applying the filling material.

13. The method of claim 12 in which the step of applying the filling material is followed by a step of leveling the filling material.

14. The method of claim 11 in which the step of removing the separator ring is followed or preceded by curing the filling material.

15. The method of claim 14 in which comprises the step of curing the filling material comprises spraying the surface of the filling material with the catalyst.

16. The method of claim 14 in which the step of curing the filling material comprises spraying the surface of the filling material with primer and then water.

17. A separator ring for separating a manhole cover and its underlying structure, the separator ring comprising

An elongated body capable of bending in a circle or other shape and having two opposing ends;

and

Male and female adjusters, each located at an opposing end, the male adjuster fitting inside the female end to establish the length around the manhole cover.

18. The separator ring of claim 17 further comprising a handle or separator ring lifter to pull the separator ring free from the filling material placed atop the manhole cover.
