These beads help improve the visibility of traffic lines at night and in poor weather, making roads safer for drivers. Although both standards relate to road marking glass beads, they cover different application methods. EN 1423 mainly applies to drop-on glass beads, while EN 1424 applies to premix glass beads. What Are Reflective Glass Beads for Road Marking? Reflective glass beads are small, transparent spheres added to road marking materials. When vehicle headlights shine on them, the beads return part of the light toward the driver. This process is known as retroreflection. As a result, road markings become easier to see at night, in rain, or under other low-visibility conditions. Reflective glass beads are commonly used for: What is the EN 1423 Standard? EN 1423 is a European standard for drop-on materials used in road marking applications. It covers glass beads, anti-skid aggregates, and ..."}
