Abstract
A roadway reflector is both durable and easily embedded into an opening in a roadway. The roadway reflector in one presently preferred embodiment is preferably circular or disk shaped so it can be inserted into a preformed circular hole in the roadway. A reflector includes two primary components, one of which is an upper member which can be easily coupled to the base member by a plurality of mating tabs and notches in the respective components. An expansion ring is inserted into the base member to expand the base member into a friction fit with the opening in the roadway. A resilient membrane or web is included in the base member and surrounds the upper reflective member so that as a snow plow blade, vehicle tire or the like passes over the reflector, the upper member is depressed downwardly into a cavity in the base member. After the item passes the reflector, the resilient membrane flexes similar to a hinge to thereby rebound the upper member upwardly to its normal position which projects upwardly from the surface of the road.
