HORIZONTAL ROAD SURFACE MARKING
The invention relates to road construction, and specifically, to road marking using special materials (road-marking materials) with reflective additives (micro-glass beads) applied thereto. The technical result of the proposed invention consists in increasing the retroreflection factor of the road marking and making it independent of the color (whiteness, brightness) of the road marking material (thermoplastic, cold plastic, paint). The invention is used as follows. Light sources, such as car headlights, emit radiation, including in the form of visible light. A major portion of the light beams directly incident onto a pavement (6) is absorbed. According to the first embodiment, a portion of all incident light beams is partially reflected directly from a road marking layer (4) and returned in the opposite direction. In both embodiments, a portion of the light beams is incident upon an extending portion (1). Since no additional layer (8) is present on the surface of the extending portion (1), the light beam is partially reflected and, upon refraction, passes inside a micro-glass bead (2). Having passed through the micro-glass bead (2), the light beams are almost completely reflected from the interface between the glass and additional layer (8), which is present along the entire surface of the micro-glass bead (2), except for the extending portion (1). Majority of these reflected light beams is returned to the light source.
