Abstract
A road marker having a collar for mounting a reflector to the surface of the road. The collar is a generally flat disk, having a pair of diametrically opposed projections. The projections have inner planar surfaces to receive a reflector therebetween and curved outer surfaces to facilitate the passage of tires over the marker. The projections have a width and height greater than that of the reflector to protect the ends of the reflector from abrasion. A recess is provided for mounting the reflector to the collar. A plurality of shallow apertures are formed on the bottom surface for receiving a mounting compound for adhering the collar to the road surface.
