Abstract
A snowplowable retro-reflective pavement marker having a reflector mounted between a pair of flanged side ramps and a pair of center ramps. The side ramps have longitudinal flanges extending outwardly from each of the ramps to position the base properly with respect to the road surface. The flanges are tapered to provide a smooth contour for guiding snowplow blades when approaching from the side. The center ramps extend longitudinally on either side of the reflector to guide a snowplow blade when it engages the marker at a steep angle.
