Product Description
High Visibility Glass Beads for Road Marking - Retroreflective Glass Spheres for Thermoplastic Road Paint | AASHTO Standard
Road marking glass beads are manufactured from glass sand and recycled glass materials. Through high-temperature melting processes, these materials form small spherical glass beads that appear colorless and transparent under microscopic examination, with diameters ranging from 75 to 1400 microns. The primary production method for reflective glass beads is the flame floating process.
These glass beads serve two main functions in road marking applications: as premixed materials to ensure continuous reflectivity throughout the marking's lifespan, and as surface-applied materials during construction to provide immediate reflective properties.
