AASHTO Type I Pavement Marking Paint Reflective Glass Beads Hot Melt Reflective Glass Beads
Description:
Glass beads are used for road markings in the following ways:
Retro - reflectivity
- When vehicle headlights shine on road markings with embedded glass beads, the beads reflect the light back to the driver's eyes. This makes the markings highly visible at night or in low - light conditions, improving road safety.
Durability
- They help markings last longer. Glass beads are hard and can withstand the wear and tear of vehicle traffic and the elements, like rain and snow. As cars drive over the markings, the beads stay in place and continue to provide reflectivity.

Do different sizes of glass beads affect their performance in road marking?
Yes, different sizes of glass beads do affect their performance in road marking.
Smaller glass beads (around 0.1 - 0.4 mm in diameter) can provide a smoother surface texture to the road marking. However, they may not have as high a retro - reflectivity as larger beads because they have less surface area to reflect light back to the driver's eyes.
Larger glass beads (about 0.6 - 1.0 mm) generally have better retro - reflectivity. They can effectively reflect light from vehicle headlights over a greater distance and at wider angles. But if they are too large, they may protrude too much from the road - marking material, leading to a less smooth surface and a higher risk of being dislodged by traffic.
The ideal size range for glass beads used in road marking is usually between 0.4 - 0.85 mm, as this provides a good balance between retro - reflectivity and surface durability.
Application:
Road marking glass beads have several important applications:
Traffic Safety
- They are used in road markings such as center lines, edge lines, and lane dividers. When vehicle headlights shine on the markings, the glass beads reflect light, making the markings highly visible at night or in low - light conditions. This helps drivers clearly see the road layout and boundaries, reducing the risk of accidents due to poor visibility.
Durability
- Glass beads improve the durability of road markings. They are embedded in the paint or thermoplastic material used for markings. As vehicles drive over the markings, the beads help protect the marking material from being worn away quickly by friction, thus extending the service life of the road markings.
