REFLECTIVE ROAD MARKINGS

REFLEKTIERENDE FAHRBAHNMARKIERUNGEN

REFLECTIVE MATERIALS WITH DIRECTED REFLECTION CONTRIBUTE LARGELY TO THE EARLY RECOGNITION OF IMPORTANT INFORMATION AND PROVIDE ROAD USERS WITH A LARGE MEASURE OF SAFETY. DEVICES SUCH AS ROAD STUDS, MARKER POSTS, TRAFFIC AND INSTRUCTION SIGNS ARE ALL EXAMPLES OF THE USE OF VERTICAL REFLECTION, I.E. THE REFLECTING SURFACES ARE VERTICAL TO THE LIGHT SOURCE AND TO THE ROAD. ROAD MARKINGS ARE AN EXAMPLE OF HORIZONTAL REFLECTION. THIS REFLECTION IS ACHIEVED THROUGH FINE GLASS BALLS ADDED TO THE PAINT OR THE PLASTIC MARKING MATERIAL. THE WORKING OF GLASS BEADS INTO HORIZONTAL MARKINGS AS SPHERICAL LENSES INCREASES BOTH THE MECHANICAL STRENGTH AND THE DURABILITY OF THE MARKINGS AND PROVIDES IMPROVED NIGHT VISIBILITY THROUGH RETRO-REFLECTION. THIS NIGHT VISIBILITY IS RETAINED EVEN AS THE MARKINGS WEAR AWAY, AS NEW SPHERICAL LENSES ARE CONSTANTLY BEING FREED, AND THESE TAKE OVER THE REFLECTION.
