Flexible, raised pavement markers having improved shapes which take advantage of relief cuts and ribs to increase the durability and retention of reflectivity. One embodiment of such a marker comprises: a flexible body made of sponge rubber and having a raised surface connected to a base portion through a connecting portion, a reflective film attached to the raised portion, and a pressure-sensitive adhesive on the base. Relief cuts along the back of the connecting portion provide a bending or folding action whereby the reflective film is made to lie flat when a tire passes over the marker, thus protecting the reflective sheeting from scuffing.

A pavement marker comprising a body: (a) made of an elastomer having a compressive strength at 25% compression of about 40 to 100 kilopascals; (b) having a base portion with an approximately flat bottom which can be attached to a road without using either an anchor or a recess in the pavement; (c) having a raised surface adapted to face on-coming traffic when the marker is mounted on a road, to which surface is attached a reflective material; and (d) having a shape which supports the raised surface through a connecting portion of the body extending between the back of the raised surface and the base portion, said connecting portion forming an acute angle with the plane of the bottom of the base portion and having at least two ribs located on the back side of said connecting portion which ribs are oriented parallel to the plane of the base portion.
