ABSTRACT:
An extrudable roadway marker (11) is provided having enhanced stability. The roadway marker has a constant cross section along a centerline (A--A) that allows the roadway marker to be manufactured by extrusion. The base (13) of the roadway marker has a series of adjacent parallel grooves (27) that provide a large adhesive surface. Downwardly extending gripping edges (19) assist in attaching the roadway marker to a roadway surface. In one form, the sides of the roadway marker have reflective tape recesses (17) for receiving and protecting reflective strips 23. A raised rumble portion (15) provides a physical rumbling cue. A recess (25) reduces the weight of the roadway marker. The ends of the marker can be sheared flat or inclined. The parallel grooves may form sharp teeth where they join. The sharp teeth project away from the center of the roadway marker.
