ABSTRACT:
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.
