发明名称 FLEXIBLE RAISED PAVEMENT MARKER, MOUNTING DEVICE AND METHOD
摘要 A flexible, raised snowplowable pavement marker having a top portion that readily deforms downwardly into a base portion when impacted by vehicular traffic or a snowplow blade. Markers installed in a cavity bored in pavement are anchored in place with grouts or alternatively within an annular ring mounting device. The marker body may be black in color to take advantage of solar activity in improving marker performance and longevity and may be vented to atmosphere to facilitate the downward deflection of the top portion of the pavement marker. A retroreflective sheeting is affixed to the marker so that the marker is highly visible to motor vehicle drivers at nighttime.
