The Relationship Between Glass Beads And Thermoplastic Paint
This is an experiment that tracks decline data during the lifetime of road marking glass beads manufactured by different manufacturer and techniques.
Traffic road markings must have the visual recognition performance—retroreflectivity. And the retroreflectivity of road marking is affected by a variety of reasons. We will observe the changed situations of glass beads manufactured by different techniques and paints through a group of photos, specifically to solve the problem of persistent retroreflection of thermoplastic paint.
Glass beads selections: Hydrofluoric acid cleaned glass beads, strong alkaline cleaned glass beads, Furnace melted glass beads, imported glass beads, other glass beads and etc.
Below is a group of photos, which take from different lanes and bring them back to the lab for further research. The glass beads were not found to fall off, and the retroreflective data didn’t meet the requirements.
Time period: 3 months, 6 month, 1 year etc.
