SNOWPLOWABLE PAVEMENT MARKER AND METHOD AND APPARATUS FOR INSTALLING SAME ABSTRACT OF THE DISCLOSURE A low-profile snowplowable pavement marker includes a metal base member having two arcuate-bottom keel members inter- connected by an arcuate-bottom support member, the upper sur- faces of the keel members respectively defining inclined ramps each having an inner edge and an outer edge respectively rising at different angles from a basal plane at one end of the base member toward the other end thereof to corresponding coplanar top surfaces, the support member having a support surface lying below the basal plane for supporting thereon a cube corner reflex reflector assembly partially recessed below the basal plane. The keel members and the support member are respectively secured in complementary arcuate recesses with the basal plane substantially coplanar with the roadway surface, the recesses being cut in the pavement with circular blade cutting apparatus without moving the cutting apparatus along the pavement. A bidirectional marker is shown as well as cutting apparatus for cutting the three recesses therefor simultaneously. A mono- directional pavement marker is shown, with two forms of cutting apparatus for respectively cutting the keel recesses either simultaneously or sequentially with the support member recess.
