Abstract: Disclosed are improved snowplowable pavement markers (130,230) held fixedly to a roadway (180,280) by adhesive (185,285). The markers (130,230) include a holder (131,231 ) and at least one transversely arranged reflector (32) to retroreflect incident light from headlights of approaching vehicles. The holders (131,231 ) have a pocket (155,233) for supporting the reflector (32). One or more through openings (156,250) having angled sides (157,251 ) are defined in the bottom of the pocket (155,233) so that when the marker (131,231 ) is installed in an adhesive bed on the pavement (180,280), adhesive (185,285) flows into contact with the holder (131,231 ) and the bottom of the reflector (32) to simultaneously affix both to the pavement (180,280). Reflectors (32) may be replaced by simply chiseling an old reflector out of the holder pocket (155,233) to create a flat bottom surface in the pocket to which a bead of mastic adhesive (185,285) is applied and a new reflector (32) is subsequently installed. This new marker construction applies to both raised and recessed snowplowable pavement markers.
