Title: Pavement marker

Abstract: Disclosed herein is a pavement marker for engagement with an underlying roadway for providing a marking visible from an oncoming vehicle on the roadway surface. The pavement marker comprises a lens member of light-transmitting synethetic resin including a front face having a light-receiving and refracting portion adapted to be inclined at an angle of at least 15° and a rear face having reflex reflective means for reflecting light transmitted through the light-receiving and refracting portion back to the source. The pavement marker has an untempered glass sheet fixedly disposed on the light-receiving and refracting portion and the glass is in compression throughout the expected temperature range to which the pavement marker is exposed in use.
