Reflective pavement marker

Abstract

A reflective pavement marker includes a shell having a top wall, a side wall extending from an end of the top wall, and reflective end walls extending from an other end of said top wall, wherein the shell forms an interior cavity. The reflective pavement marker also includes a reflective portion integral with the reflective end wall, a reflective coating covering the reflective portion and a bonding coating covering at least the reflective portion. The reflective pavement marker further includes a filler material within the interior cavity of the shell.

What is claimed is:  
     
         1 . A reflective pavement marker comprising: 
 a shell having at least one side wall having a reflective portion, wherein said shell forms an interior cavity, said reflective portion having an inner surface partially defining said cavity;    a reflective coating covering said inner surface of said reflective portion;    a bonding coating covering at least said reflective coating; and    a filler material disposed within the interior cavity of said shell.    
     
     
         2 . A reflective pavement marker as set forth in  claim 1  wherein said shell includes a top wall, side wall and reflective end wall with reflective portion that are integral and formed as one piece.  
     
     
         3 . A reflective pavement marker as set forth in  claim 1  wherein said reflective portion includes a plurality of integrally formed cube-shaped members arranged in a grid pattern.  
     
     
         4 . A reflective pavement marker as set forth in  claim 1  wherein said reflective coating is a metal material.  
     
     
         5 . A reflective pavement marker as set forth in  claim 1  wherein said bonding coating is a bonding primer.  
     
     
         6 . A reflective pavement marker as set forth in  claim 5  wherein said bonding primer is an acrylic latex primer.  
     
     
         7 . A reflective pavement marker as set forth in  claim 5  wherein said bonding primer is a water based primer.  
     
     
         8 . A reflective pavement marker comprising: 
 a shell having at least one side wall having a reflective portion, wherein said shell defines an interior cavity, and said reflective portion and said shell are integral and formed as one piece;    wherein said reflective portion includes a plurality of integrally formed cube-shaped members arranged in a grid pattern on an inner surface;    a reflective coating covering said inner surface of said reflective portion, wherein said reflective coating is a metal material;    a bonding coating covering said reflective coating to prevent separation of said reflective coating from said reflective portion, wherein said bonding coating is a bonding primer; and    a filler material disposed within said cavity of said shell.    
     
     
         9 . A reflective pavement marker as set forth in  claim 8  wherein said bonding primer is an acrylic latex primer.  
     
     
         10 . A reflective pavement marker as set forth in  claim 8  wherein said bonding primer is a water based primer.  
     
     
         11 . A method of forming a reflective pavement marker, said method comprising the steps of: 
 forming a shell having at least one reflective portion with an inner surface wherein the shell forms an interior cavity;    coating said inner surface with a metal material;    covering at least said metal material with a bonding compound; and    filling the cavity of the shell with a filler material.    
     
     
         12 . A method as set forth in  claim 11 , wherein said step of forming includes forming a cube corner retro-reflective portion on the inner surface of the reflective portion.  
     
     
         13 . A method as set forth in  11  wherein said bonding compound is an acrylic latex primer.  
     
     
         14 . A method as set forth in  claim 11  wherein said bonding compound is a water based primer.
