A resilient pavement marker (10) for delineating lanes and shoulders of road- ways which is not susceptible to the forces associated with plowing of the road or damage from environmental conditions. The marker (10) incorporates an assemble unit which may be readily installed within the roadway including a base housing (20), a depressible piston (40) which carries a detachable lens assembly (50), and a compressible biasing assembly (70) to facilitate depression of the piston (40) and re- turn to its original position. The piston (40) is retained within the housing by a cap (24) cooperating with the base. The cap (24) includes an opening (34) which has a lobed or scalloped configuration adapted to cooperate with the scalloped configura- tion of the piston (40) thereby preventing rotation of the piston (40) within the hous- ing. The lens assembly (50) is removable from the piston to facilitate simple replace- ment of the reflective lenses without removal or disassembly of the marker (10). The compression assembly (70) fills substantially the entire interior of the housing (20) and includes closed-cell members to eliminate absorption of moisture and damage from freezing.
