History of Glass Beads for Road Markings Glass beads have always been used to make reflective road signs. If properly embedded in the marking material, the glass beads are able to collect the incident light and reflect some of it back to the light source. It's this ability that makes these small, spherical glass particles unique. 1952: Pocock and Rhodes first studied the principle of glass ...

Why Are the Road Markings Not Removed and Repaved, but Repainted and Covered with Glass Beads? For a number of reasons, road markings are usually scattered with glass beads and repainted rather than removed and repaved. Cost-effectiveness: In general,Repainting road markings and scattering glass beads is far less expensive than removing and repaving the road. This is due to the fact that re...

How to Solve Bubbles in Road Markings? All roads should be clean and dry during the marking construction. Moisture is the most harmful factor in the adhesion of paint and pavement. The amount of moisture in the ground is enough to affect proper coating adhesion. Early morning dew and fog usually result in wet roads. If there is too much moisture on the road surface, it usually leads to blistering ...

Detailed Process of Hot Melt Marking Construction 1. Road Cleaning Before construction, the nearby area must be cleaned to ensure that there are no impurities such as oil, water, fallen leaves, weeds, etc., so as not to affect the adhesion, smoothness, and reflective effect of the markings. 2. Full Scale Plotting During the setting out process, calculations and ...
