Application Summary AI generated
GB/T 24722-2009 specifies the technical requirements, test methods, inspection rules, and packaging for glass beads used in road marking materials. It is applied in the production and quality control of reflective road markings, such as thermoplastic or cold-applied paints, to ensure retroreflective performance and durability on highways, urban roads, and airport runways. The standard is used by manufacturers, construction contractors, and testing laboratories to verify bead size distribution, refractive index, and resistance to weathering.
