Abstract: An improved casting for a road marker having a reflector and a method of installation for the road marker are disclosed. The method of installation includes forming a groove that has a rectangular geometry when view from above and is longitudinal oriented parallel to the direction of the road. The groove can also have a deeper section at the center with the same geometry of the groove but with a bigger radius to receive one or more legs from the road marker of the present invention.

Abstract: A pavement road marker is provided mounted to a road having a main shell or body having a top portion. The top portion of the body being generally planar and including a lens mounted thereon. The lens is mounted within the body so that the plane created by the lens is beneath the plane created by the planar surface of the body portion. The assembly further includes an inner cavity having a first surface and a first opening. The first opening is oppositely disposed from the top portion. The first surface of the inner cavity includes various structural elements such as protrusions, legs, or dimples. The protrusions, legs, and dimples increase surface area to improve adhesion of potting to the inner surface of the housing to fill the cavity of the housing. The legs having a lateral surface which extend on a plane normal to an outer surface of the body.
