To make road lines easier to see in low-light conditions, reflective glass beads are widely used in road marking materials. But how do road marking glass beads work? Why do they make road markings brighter at night? And what is the difference between drop-on and intermix glass beads? In this article, we will explain their working principle, main types, and key selection factors. What Are Road Marking Glass Beads? Road marking glass beads are small, transparent spherical particles used to improve the nighttime visibility of pavement markings. They are commonly applied to road marking paints, thermoplastic paints, and other pavement marking systems. Their main function is to reflect vehicle headlights back toward drivers through a process called retroreflection. This makes lane lines, road edges, pedestrian crossings, and traffic symbols easier to identify at night. How Do Road Marking Glass Beads Work? The working principle ..."}
