Method for repairing holes in pavement

Abstract

A method for repairing a hole in pavement comprises the steps of filling the hole with a filling material. One or more waterproofing cover sheet are placed over the hole, such that the hole and a portion of a surrounding area of the hole are covered. The waterproofing cover sheet is heated so as to make the waterproofing cover sheet adhere to the pavement, whereby the waterproofing cover sheet generally prevents water from infiltrating into the repaired pavement.

1 . A method for repairing a hole in pavement, comprising the steps of: 
 i) filling the hole with a filling material;    ii) placing at least one waterproofing cover sheet over the hole, such that the hole and a portion of a surrounding area of the hole are covered; and    iii) heating the waterproofing cover sheet so as to make the waterproofing cover sheet adhere to the pavement;    whereby the waterproofing cover sheet generally prevents water from infiltrating into the repaired pavement.    
   
   
       2 . The method as defined in  claim 1 , wherein step i) is performed by inserting the filling material into the hole and compacting the filling material.  
   
   
       3 . The method as defined in  claim 2 , wherein the filling material is cold asphalt.  
   
   
       4 . The method as defined in  claim 1 , further comprising a step of cleaning the surrounding area of the hole, prior to step ii).  
   
   
       5 . The method as defined in  claim 1 , further comprising a step of heating the area surrounding the hole, performed prior to step ii), so as to ensure that the waterproofing cover sheet generally adheres to the pavement.  
   
   
       6 . The method as defined in  claim 1 , further comprising a step iv) of covering the waterproofing cover sheet with loose material so as to reduce the tackiness of the waterproofing cover sheet.  
   
   
       7 . The method as defined in  claim 6 , wherein step iv) is performed by covering the waterproofing cover sheet with existing loose material found on the pavement.  
   
   
       8 . The method as defined in  claim 1 , wherein the waterproofing cover sheet has a layer of low-heat-resistant material supporting a layer of waterproof material, the layer of low-heat-resistant material being incinerated during step iii).  
   
   
       9 . The method as defined in  claim 1 , wherein the waterproofing cover sheet has a layer of low-heat-resistant material supporting a layer of waterproof material, the layer of low-heat-resistant material being removed from the layer of waterproof material prior to step iii).  
   
   
       10 . The method as defined in  claim 5 , wherein the step of heating the waterproofing cover sheet is performed by generally liquefying the layer of waterproof material.  
   
   
       11 . The method as defined in  claim 1 , further comprising a step of exposing a material of the pavement about the periphery of the hole, prior to step ii).  
   
   
       12 . The method as defined in  claim 11 , wherein the step of exposing the material of the pavement is performed by raking/scraping the pavement about the periphery of the hole while heating the periphery of the hole.
