Abstract:
1. A preformed thermoplastic pavement marking material comprising a taggant composition wherein said taggant composition is a carrier consisting essentially of chemical elements with an atomic number between 29 and 60 and wherein said taggant composition includes a taggant concentration of said chemical elements that is within the range of 200 ppm to 5000 ppm and such that said taggant composition is identifiable before, during or after application of said preformed thermoplastic pavement marking material to a pavement surface and wherein said pavement marking material is selected from a taggant composition wherein taggant microparticles of said taggant composition consist of the group selected from combined with melamine-sulphonamide-formaldehyde copolymer and phenol-formaldehyde resins and said taggant composition is further selected from the group consisting of; plasticizers, glass beads, calcium carbonate, feldspar, and silica, and wherein said taggant concentration is greater than the standard error of the measurement equipment required to determine said taggant concentration of said chemical elements.
