During the production of road painting, put glass bead into paint based on the ratio of 18-25% (weight percentage), so that the road paint can still keep reflectivity during wear and friction. The ratio is refer to the specification of Communication Industry Standard of the People’s Republic of China JT/T280-2004, the standards may be different from different countries and areas.

According to the specification of Communication Industry Standard of the People’s Republic of China GB/T24722-2009, the granulometry is shown in the table below:

Size scope (μm) Alternative NO.(mesh) content(%)
>600 >30 0
600-300 30-50 50-90
300-150 50-100 5-50
<150 <100 0-5
 
Specific gravity:2.4-2.6g/cm3
Reflectivity:≥1.50
Roundness:≥80%
Contained ratio of magnetic particles:≤0.1%

The appearance of glass bead should be colorless, loosen and spherical particle, should be clean without impurity, and without agglomeration.
