These materials are dropped on to paints, thermoplastics, cold plastics and any other marking product applied in a liquid state, immediately after application to the road surface. The requirements taken into consideration in this standard are: - glass beads: granulometry, refractive index of the glass, chemical resistance, quality, surface treatments; - antiskid aggregates: granulometry, chemical characteristics, friability, colours.
