ABSTRACT:
A raised road marker has a flat bottom surface with an outer periphery. At least one cavity opens onto the bottom surface laterally inwardly of the periphery and extends upwardly into the marker body. A venting groove extends along the bottom surface from the cavity to the periphery to provide a vent for air trapped in the cavity when the marker is urged into a pool of adhesive to secure the marker to a roadway. The venting of air provides a stronger bond between the marker and adhesive. Markers having a rounded top surface may be provided with a flat bottom portion with abutment surfaces to facilitate movement of a line of the markers in an automated system.
