Abstract
A pavement marker for providing a marking signal on the roadway surface capable of reflecting light impinging thereon and for reflecting light back toward the source thereof so as to be visible to a driver in an oncoming vehicle, comprises a base having a generally horizontal bottom surface and at least one wall positioned in use in the direction of an oncoming vehicle. A lens member of light-transmitting synthetic resin is carried by the base and has a front face oriented so as to make an acute angle of between about 15.degree. and about 60.degree. with the base to rise above the roadway surface upon which the pavement marker is to be installed. The base includes means cooperating with the rear surface of the lens member for providing a plurality of hermetically sealed cells, the lens member including a plurality of retro-directive cubecorner-type reflector elements in the portions thereof occupied by the cells, the reflector elements being oriented to reflect light impinging upon the front face of the lens member in the areas corresponding to the cells back toward the source thereof to render the reflector structure highly visible at night. Abrasionlimiting means in the form of a thin glass sheet overlies the front face of the lens member in the areas occupied by the reflector elements, the glass sheet reducing the degradation of optical efficiency normally caused by abrasive tire contact on the lens member while allowing adequate cleaning by tire wiping action so that optical efficiency of the pavement marker is enhanced. In a second embodiment, spaced, abrasion-limiting ridges parallel to the direction of traffic are carried by a portion of the front face of the lens member and raised thereabove for forming a plurality of channels, the ridges absorbing substantially the full impact forces and abrasive contacts of tires for minimizing abrasion of the other portions of the lens member while adequate cleaning of the lens member is obtained by the action of tires, including a combination of high velocity air and rainwater being forced through the channels by passing tires.
