ABSTRACT:
A self-cleaning pavement marker adapted to be installed in a groove below the plane of the driving surface of an associated roadway to provide a retroreflective light signal visible to an oncoming vehicle. The marker comprises an integrally formed elastomeric body adapted to be positioned in a longitudinally extending groove cut in the roadway surface. The body includes an upper portion for receiving a retroreflective lens means. The lens means is effective a retroreflect light impinging upon its front face from an oncoming vehicle back toward the vehicle. The upper body portion of the marker is depressible between a normal position wherein the lens means is positioned below the plane of the associated roadway to retroreflect light impinging on the front face from an oncoming vehicle back toward the light source, and a depressed position caused by the force of a vehicle tire passing over the upper body portion. Wiping means is positioned below the plane of the associated roadway and is integrally formed with the body, and is positioned adjacent to the front face of the lens means, and is configured and arranged such that the wiping means does not interfere with the retroreflective function of the lens means when the body portion is in the normal position. Upon depression of the upper body portion to the depressed position, and its return to the normal reflecting position, the front face of the lens means moves past the wiping means and in direct contact therewith, whereby the wiping means effects a debris-cleaning and wiping function. The marker is effective as a snowplowable marker, particularly where studded tires are permitted.
