Method for securing preformed pavement marking constructions

Abstract

A method for securing a pavement marking construction to the pavement includes sealing the perimeter edge of the pavement marking construction by applying a structural adhesive around the perimeter edge of the pavement marking construction. The seal is applied so that it overlaps the top surface of the pavement marking construction at the perimeter edge and extends to the pavement surface. The sealed pavement marking construction will be more durable and will resist peeling from the pavement, even when subjected to heavy traffic.

What is claimed is:  
     
         1 . A method for securing a preformed pavement marking construction having a top surface and at least one perimeter edge to a pavement surface comprising the steps of: 
 adhering the preformed pavement marking construction to the pavement surface;    providing a curable structural adhesive;    applying the curable structural adhesive to the at least one perimeter edge of the preformed pavement marking construction such that the curable structural adhesive overlaps a portion of the top surface of the preformed pavement marking construction at its at least one perimeter edge and a portion of the pavement surface; and    curing the curable structural adhesive.    
     
     
         2 . The method of  claim 1  wherein the curable structural adhesive is selected from the group consisting of one- and two-part epoxies, multi-component polyurethanes, silicone adhesives; UV curable adhesives; UV curable resins, and combinations thereof.  
     
     
         3 . The method of  claim 2  wherein the curable structural adhesive is a two-part epoxy.  
     
     
         4 . The method of  claim 1  wherein the curable structural adhesive is applied using a caulking gun.  
     
     
         5 . The method of  claim 1  wherein the curable structural adhesive is applied around the entire perimeter of the pavement marking construction.  
     
     
         6 . The method of  claim 5  wherein the curable structural adhesive is applied as a strip having a width between about 0.2 inch and about 0.8 inch.  
     
     
         7 . The method of  claim 5  wherein the width is about 0.3 inch.  
     
     
         8 . The method of  claim 6  wherein the width overlaps the perimeter of the pavement marking construction by between about 0.1 inch and about 0.4 inch.  
     
     
         9 . The method of  claim 8  wherein the width overlaps the perimeter of the pavement marking construction by about ⅛ inch.  
     
     
         10 . A method for securing a pavement marking construction having a top surface and at least one perimeter edge that has been adhered to a pavement surface comprising the steps of: 
 providing a curable structural adhesive;    applying the curable structural adhesive to the at least one perimeter edge of the pavement marking construction such that the curable structural adhesive overlaps a portion of the top surface of the pavement marking construction at its at least one perimeter edge and a portion of the pavement surface; and    curing the curable structural adhesive.    
     
     
         11 . The method of  claim 10  wherein the curable structural adhesive is selected from the group consisting of one- and two-part epoxies, multi-component polyurethanes, silicone adhesives; UV curable adhesives; UV curable resins, and combinations thereof.  
     
     
         12 . The method of  claim 11  wherein the curable structural adhesive is a two-part epoxy.  
     
     
         13 . The method of  claim 10  wherein the curable structural adhesive is applied using a caulking gun.  
     
     
         14 . The method of  claim 10  wherein the curable structural adhesive is applied around the entire perimeter of the pavement marking construction.  
     
     
         15 . The method of  claim 14  wherein the curable structural adhesive is applied as a strip having a width between about 0.2 inch and about 0.8 inch.  
     
     
         16 . The method of  claim 15  wherein the width is about 0.3 inch.  
     
     
         17 . The method of  claim 16  wherein the width overlaps the perimeter of the pavement marking construction by between about 0.1 inch and about 0.4 inch.  
     
     
         18 . The method of  claim 17  wherein the width overlaps the perimeter of the pavement marking construction by about ⅛ inch.  
     
     
         19 . A method for marking a pavement surface comprising the steps of: 
 adhering a pavement marking construction having a top surface and at least one perimeter edge to the pavement surface;    applying a curable structural adhesive to the at least one perimeter edge of the pavement marking construction such that the curable structural adhesive overlaps a portion of the top surface of the pavement marking construction at its at least one perimeter edge and a portion of the pavement surface; and    curing the curable structural adhesive.    
     
     
         20 . The method of  claim 19  wherein the curable structural adhesive is selected from the group consisting of one- and two-part epoxies, multi-component polyurethanes, silicone adhesives; UV curable adhesives; UV curable resins, and combinations thereof.
