Thermoplastic markings are heat-applied materials that become malleable when heated, then cool and harden to create extremely durable markings with extended lifespan. They offer superior adhesion, excellent retroreflectivity through embedded glass beads, and better durability on asphalt surfaces. Paint-based markings use water-based or oil-based formulations that are easier to apply but typically have shorter lifespans. Thermoplastic requires specialized heating equipment and higher initial costs but provides better long-term value through extended lifespan and reduced replacement frequency.
