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

exact text as granted — not AI-modified
What is claimed: 
     
         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.
