Glass Beads For Road Marking

Reflective glass beads is a kind of micro spherical glass,which is widely use in road marking and line striping, it can improve the reflective effect of road marking paint,when the light shot on the marking line,the glass beads mixed in marking line will reflect the car light back,make the driver see the travel direction, greatly improve the driving safety at night.

Different countries have its own standard,we have all types and also can customized to meet specific project requirements.

Products standards

Different countries have its own standard, such as BS6088A, BS6088B,  AASHTO1, AASHTO2; they have different physics and chemistry function, we have complete standard for all over the world,or can customized according customer’s request.

The factors affecting the glass beads reflective result

  • Bonding between glass beads and marking paint
  • Refractive index of glass beads
  • Transparency of glass beads
  • Roundness of glass beads

The glass beads are colorless and transparent small balls, which have the functions of refraction, focusing and directional reflection to light. Scattering glass beads on the paint can improve the visibility, improve the brightness and durability of the road marking, and help drivers see the marking clearly on rainy nights or at night.

After premixing in the road marking paint or spreading on the coating surface, a reflective layer will be formed on the bottom surface of the glass sphere. The light emitted into the glass bead will be refracted in it and reflect the light to the direction of the light source. This reflection of the glass bead is called the regression reflection of light. When the automobile headlamp irradiates the road surface, the visibility of the road marking is improved because the light returns to the driver’s eyes.

Glass beads are mainly used in normal temperature and hot-melt road marking coatings. One is sprinkled with glass beads and the other is premixed glass beads. Surface glass beads are directly spread on the wet marking paint after the paint draws the marking line on the road. The premixed glass bead is to add the glass bead into the coating pavement and mix it evenly before the pavement marking coating is drawn. Premixed glass beads can ensure long-term reflection within the service life, while surface scattering glass beads can play a timely reflection.
