Road Marking Glass Beads

During the application of paint on road work,thermoplastic paint should be heated to a certain level and used on the road surface as marking line,drop on glass bead should be dropped on the surface of line while it is still wet to increase the reflectivity of road marking line.
According to the specification of Communication Industry Standard of PRC No.GB/T24722-2009-,the granulometry of drop on glass bead is shown as table below,other parameters are the same with intermix galss bead.
 
We can produce glass beads based on standards of different countries and areas,such as BS6088, AASHTO M247,EN1423/EN1424-1998,KS L2521 ETC.
Using quantity and method of drop on beads can be varied by requirements of reflectivity of different countries.
