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.

A traffic lane marker system, including a road, a solid raised marking strip on the road having at least one reflecting stripe thereon, the stripe carrying small, reflectivity-increasing glass spheres or glass particles therein, the at least one stripe running longitudinally with the marking strip, the marking strip being narrower than the road and following the curvature of the road, the marking strip lying above the road surface, at least the major part of the surface of the raised marking strip having sloping sides to drain rain from its surface, the marking strip being formed from asphalt, asphalt slurry or epoxy and stone, whereby the marking strip permits increased visibility of the marking strip during darkness hours, during times of rain, to thereby enhance the contrast between the marking strip and the road surface. A method of making a raised road marker strip for a road, including the steps of (1) extruding a generally convex strip of a flowable composition along a road to be marked so that the generally convex extruded marker strip lies on the top surface of the road (2) forming rain drainage grooves in the strip at an angle to the longitudinal axis of the road, (3) coating the strip with at least one reflecting stripe running longitudinally therewith.
