ABSTRACT:
A low profile, bi-directionally snow-plowable road marker having a cast metal base or body of generally square plan configuration formed on its underside with laterally spaced oppositely curved arcuate rib members flanked by transversely extending webs and protrusions located centrally of the body and acting with the rib members to self-center the cast body in a shallow arcuate depression of single radius formed in a roadway pavement; the webs and protrusions being configured to evenly distribute adhesive over the bottom, sides, ends and over portions of the upper side of the cast body to encapsulate and lock the same securely in the pavement depression. The upper side of the cast body is distinguished by a pair of downwardly sloping sub road surface vision ramps extending inwardly of opposite ends of the cast body and terminating at their lower ends in co-planar mounting platforms which are separated by a vertically extending wall having a transversely protruding and overhanging canopy portion along its upper end. A reflective light signal assembly is adapted to be mounted on either one or both of the platforms as selected; such being protectively captured and locked against vertical and lateral displacement by the overhanging canopy beneath which it is mounted. Locators having upper curvilinear surfaces and co-planar bottom surfaces are provided along opposite sides of the cast body to engage the roadway surface and thereby vertically locate the body casting in the pavement depression so that there is minimal protrusion of the marker above the roadway surface. The signal assemblies are protectively located on the bottom of the vision ramps and shielded from contact with vehicle tires and snowplow blades by the canopy.
