The applicator can be made up of stainless steel or mild steel. With it is the glass bead dispenser where glass beads are placed. Glass beads dispenser can be a rotary type where the flow of beads is based on the speed of the machine or it can be the gravity type where beads are poured when the slot is opened.
Marking materials are in powder form and composed of binder, titanium dioxide pigment, and pre-mix glass beads. These are placed on bags or sacks. Bags are poured on the preheater for melting and mixing. It is embossed once applied and it is typical 1.5mm or 3.2mm thick. Additional glass beads can be used and are distributed throughout the coating which improves the appearance of traffic lines by increasing its visibility at night.
