Abstract
A snow plowable pavement marker including a body having a base adapted to be secured to the surface of a roadway in such a manner that the fore and aft axis of the body extends parallel to the direction of travel of vehicles. A pair of snow plow ramp sections are secured to the body on opposite sides of the fore and aft axis thereof, the ramp sections including a pair of oppositely projecting snow plow ramps. The snow plow ramps each has an inner wall adjacent the fore and aft axis, an outer wall on the opposite side of the respective inner wall from the fore and aft axis, and a reinforcing rib extending along the length of the ramp between the respective inner and outer walls thereof. Each of the snow plow ramps has an enlarged end adjacent the pavement marker body, and decreases in cross-section to a relatively sharp tip portion at the distal end thereof spaced from the pavement marker body such that snow plows and like equipment will first contact the snow plow ramps at the tip portions and be guided over the pavement marker body by the snow plow ramps. Drain slots are formed in the edges of the inner walls, reinforcing ribs and outer walls of the snow plow ramps adjacent the pl…
