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 plane of the base providing a passage for drainage of liquid from the space between the snow plow ramps. The snow plow ramps are made up primarily of plastic material, with the reinforcing rib, in one embodiment, being of metal interlocked with the plastic material.

A snow plowable pavement marker comprising: a body having a fore and aft axis that extends parallel to the direction of travel when the body is secured to the surface of a roadway and a transverse axis extending perpendicularly with respace to said fore and aft axis; means defining a base plane for said body; said body having a top wall spaced from said base plane, a pair of outer walls extending in opposite directions from said top wall to said base plane with said fore and aft axis intersecting said outer walls, and a pair of side walls spaced from each other on opposite sides of said fore and aft axis and depending from said top wall and extending between said pair of outer walls; a pair of snow plow ramp sections each secured to one of said side walls; each of said snow plow ramp sections including a pair of snow plow ramps extending in opposite directions from said transverse axis; each of said snow plow ramps having an enlarged end adjacent said transverse axis and decreasing in cross-section to a tip portion at the distal end thereof spaced from said transverse axis such that snow plows and like implements moving toward said body in a direction from said tip portion will be guided over said body by said snow plow ramps; each of said snow plow ramp sections having an outer side wall extending from the tip portion of one of its snow plow ramps to the tip portion of the other of its snow plow ramps; said outer side wall having a straight lower edge; each of said snow plow ramps having an inner side wall extending from said tip portion toward said transverse axis and diverging from the straight lower edge of said outer side wall in the direction of said transverse axis; each of said snow plow ramp sections having a V-shaped metal reinforcing member with its apex located at said transverse axis and a pair of legs extending outwardly with respect to said body from said apex portion to said distal ends of said snow plow amps to define reinforcing ribs for said respective snow plow ramps to define reinforcing ribs for said respective snow plow ramps, said reinforcing ribs being received between the inner walls of said respective snow plow ramps and said outer wall of said ramp section; a top wall portion extending from the upper edge of each of said inner side wall to the respective leg of said reinforcing member; a top wall portion extending from the upper edge of said outer side wall to the reinforcing rib of each of said snow plow ramps; a web portion depending from each of said top wall portions on opposite sides of each of said reinforcing ribs; at least one hole in each of said reinforcing ribs; and a connector extending through each of said holes with its opposite end joined to the webs on opposite sides of said reinforcing rib to interlock said reinforcing rib with said webs; said ramp section being entirely of plastic material except for said V-shaped reinforcing member.
