Abstract:
A raised pavement marker includes a rigid reflector assembly that supports two retroreflectors. The reflector assembly is resiliently mounted over a base by a resilient membrane, which is secured to the base at its outer edge. When a vehicle contacts the reflector housing, downward forces supplied by the vehicle to the reflector housing deform the membrane, which allows the reflector housing to move downwardly to pavement level. After the vehicle has passed, the resilience of the membrane restores the reflector assembly to its raised position. Methods for installing and removing the pavement marker are disclosed.
