Road Marking Glass Beads
Road marking visibility at night can only be achieved by the application of tiny glass beads on to the surface and incorporated within road marking materials. These beads (Safety Marking Spheres) are manufactured in a full range of sizes and offer life and durability to thermoplastic road markings.
BEAD GRADATION
Glass beads are graded in precise size ranges to optimize reflective performance throughout the life of the line. As markings wear under traffic flow, some spheres are dislodged allowing previously covered spheres to become exposed and act as reflective elements.
DEGREE OF EMBEDMENT
Maximum reflectivity of individual glass spheres occurs when the optinmum degree of embedment is achieved. This occurs when 60% of the bead is below the surface of the pavement marking material and 40% is above.

Spherical beads – 70% minimum by mass
Road reflective glass beads are a kind of fine glass sphere formed by melting glass sand (waste glass) at high temperatures. It is spherical under the microscope, colorless, transparent, and the refractive index is 1.5-1.64.
Road Marking Glass BeadsRoad marking glass beads play a very important role in road safety, they are mixed or dropped on paint to reflect light back to the driver especially in the dark or poor weather conditions. When the car light shines on the marking, the glass beads will reflective, and make the marking very clear.
