ABSTRACT:
A low-profile snowplowable pavement marker is disclosed including a base member and a retroreflector. The base member has two arcuate-bottom keel members interconnected by a support member. The upper surfaces of the keel members define inclined ramps. The spacing of inner surfaces of the ramps allows retroreflectance of oncoming light while accommodating larger plow blade angles encountered in higher speed plowing. The support member has a central planar support surface for carrying the retroreflector and upwardly facing curved top surfaces providing relief in the base member between the ramps and in front of the retroreflector to allow tires of approaching vehicles to wipe the lens assembly. The housing of the retroreflector is molded from long-glass-fiber-reinforced composite thermoplastic material with a recess for accommodating a retroreflective lens element of a different thermoplastic material.
