ABSTRACT:
Described is a raised pavement marker comprised of (referring to FIG. 1) a hollow, flexible, elastomeric body 2, a reflective film 4, and a pressure-sensitive adhesive 3. Raised portion 5 provides back support for the reflective film. The hollow body has a compressive strength of less than about 100 kiloPascals at 25 percent compression so that it yields readily to vehicle wheels traversing the marker, but it regains its approximate original shape after the wheels have passed over it.
