Abstract
A lane marker for a road is defined by a generally convex strip formed, for example, from an asphalt slurry. The marker strip is placed on the road surface as by extrusion, the strip then compacted and provided with a reflective coating such as a light colored paint carrying glass particles. The coating may cover the entire strip, or may be defined by two parallel stripes. Rain drainage grooves also reflectively coated may be provided, the grooves extending across the marker strip. The marker strip exhibits particular utility during normal rainfall at night hours.
