ABSTRACT:
A pavement marker of the type including a shell-like body of light transmitting material, such as synthetic resin, having a reflective wall formed thereon, and which is filled with epoxy resin or the like for reinforcing the shell-like body against external forces applied by vehicles. The body has a fore and aft axis that intersects the reflective wall and extends parallel to the direction of travel of vehicles when the base of the pavement marker is secured to a roadway. The reflective wall has a lower edge adjacent the plane of the base that is spaced forwardly of the upper edge thereof such that the reflective wall is in nonperpendicular relationship with the plane of the base, and the outer surface of the reflective wall is curved outwardly and downwardly between the upper and lower edges. The reflective wall also curves rearwardly from the fore and aft axis on opposite sides thereof. The body also has a top surface that is convexly curved. The convex curvature of the reflective wall and top wall in opposition to external forces provides additional strength to the shell-like body.
