摘要： 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.

摘要： A self-righting roadway marker support for a flexible boundary or roadway marker has a hollow anchor sleeve sunk into a supporting surface, a mounting collar secured to said anchor sleeve, a pivot strut extending through and upward from the collar, a compressible coil spring to resiliently urge the strut into contact with the collar, and a spring stop which selectively limits the extent to which the coil spring may be compressed. An oblong, radiused or chamfered aperture formed in the collar cooperates with a spring-mounting eyebolt to prevent the strut from rotating when deflected. A tool is also disclosed for installing the marker support. The force required to deflect the support assembly is set to be less than the force that would destroy or permanently set or deform the boundary marker.
