Traditional methods involved manual painting with brushes or spray equipment, which were labor-intensive and offered limited durability. Modern techniques utilize automated spray systems, heated thermoplastic applicators, and preformed tape systems. These advancements ensure precise application, improved adhesion, and longer-lasting markings. For example, thermoplastic application involves heating solid material to a molten state, then applying it with specialized equipment, leading to faster installation and more consistent results.

b. Use of reflective beads and thermoplastic materials

Reflective beads are incorporated into thermoplastic mixtures or applied as a topcoat to enhance nighttime visibility. These micro-glass spheres function on the principle of retroreflection, directing light back toward its source. Thermoplastics, due to their high melting point and rapid setting, are ideal for dynamic conditions, allowing quick application and immediate durability. The combination of these materials significantly extends the lifespan of markings and improves safety in low-light conditions.

c. Integration of smart technologies: LED and embedded sensors
