Abstract
A resilient pavement marker for delineating lanes and shoulders of roadways which is not susceptible to the forces associated with plowing of the road or damage from environmental conditions. The marker incorporates an assembled unit which may be readily installed within the roadway including a base housing, a depressible piston which carries a detachable lens assembly, and a compressible biasing assembly to facilitate depression of the piston and return to its original position. The piston is retained within the housing by a cap cooperating with the base. The cap includes an opening which has a lobed or scalloped configuration adapted to cooperate with the scalloped configuration of the piston thereby preventing rotation of the piston within the housing. The lens assembly is removable from the piston to facilitate simple replacement of the reflective lenses without removal or disassembly of the marker. The compression assembly fills substantially the entire interior of the housing and includes closed-cell members to eliminate absorption of moisture and damage from freezing.
