Description:
There are mainly two types of glass beads used for road marking:
Standard Glass Beads
- These are the most commonly used. They have a relatively uniform
size, usually ranging from about 0.4 - 0.85 mm in diameter.
Standard glass beads provide good retro - reflectivity and are
suitable for most normal road - marking applications, such as on
highways, urban roads, and parking lots.
High - Index Glass Beads
- These beads have a higher refractive index than standard glass
beads. They are designed to provide enhanced retro - reflectivity.
High - index glass beads are often used in situations where maximum
visibility is required, such as in areas with poor lighting
conditions, sharp curves, or at intersections.

There are several sizes of glass beads used in road marking.
Typically, the diameter of glass beads for road marking ranges from
about 0.1 to 1.0 mm. The most common size range is from 0.4 to 0.85
mm. Smaller beads around 0.1 - 0.4 mm can provide a smoother
surface texture to the road marking, but may have lower retro -
reflectivity. Larger beads in the range of 0.6 - 1.0 mm generally
have better retro - reflectivity but may protrude more and affect
the smoothness of the road - marking surface if not properly
applied.
The glass material is actually colorless and transparent, but
because the glass beads have a scattering effect on light in the
entire visible spectrum, it looks white in color. But when it is
added to a colored material, it scatters the light of the material
color, so it can be widely used in any material that requires an
appearance color without affecting the original material color.
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.
