Abstract
The invention pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern marking designs replicate 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 bridging the intersections between the first and second sections, maintaining 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 for heat treatment during application.
