Pavement marking pattern and method
First Claim
1. A pre-bonded pavement marking grid and insert pattern comprising:
- an independent thermoplastic grid section, and an independent thermoplastic insert section, wherein said insert section resides within said grid section and each said insert section is coplanar, and wherein said grid section and said insert section both comprise a planar top surface and a planar bottom surface and coplanar to each other, such that said grid section is in direct contact with and adjacent to said insert section thereby forming an intersection between said grid section and said insert section,andfurther comprising an adhesive backing layer on said coplanar bottom surface, said adhesive backing layer bridging and bonding said coplanar bottom surface to form a unified pavement marking pattern thereby preventing dislodging or separation of said pavement marking pattern during handling, movement, transportation before application of said pre-bonded pavement marking to the top of a pavement surface by application of heat.

Abstract
The invention herein pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern designs for the markings are available to replicate layers of bricks, cobblestones, horizontal signage, logos and other components. The marking patterns are composed of two or more independent sections, the first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example represent bricks which are contained within the grid. As the first and second sections are generally formed from different colored, preferably thermoplastic materials, a hot melt adhesive spray is utilized on the bottom surface of the marking pattern to bridge the intersections between the first and second sections to maintain the integrity of the marking pattern for convenience during handling and application to a substrate. Preferably the hot melt spray adhesive has approximately the same softening point range as the pattern sections to accommodate heat treatment of the marking pattern during application of the marking pattern to the substrate.
