ABSTRACT:
A highway marker for implantation in a highway or roadway where a top surface of the marker is just above the roadway surface and is centered in a stripe that separates the lane or roadway from the lane or roadway shoulder. The highway marker includes an outer sleeve formed from a section of five inch steel pipe that is for installation in the road with its top edge level with the road surface and contains a steel core centered in the sleeve in rubber that extends to the inner surface of the outer sleeve, the bonded rubber tending to deflect downwardly and rebound when a force is applied onto the steel core. The steel core is center tapped to receive a bolt that is fitted through a disk shaped cap having equal spaced sloping radial ribs that extend from a raised collar to the cap edge whereby, a weight of a vehicle tire traveling up a rib will depress the cap and steel core downwardly that rebounds after passage of the vehicle tire, and which cap can be colored as with a reflective surface over one hemisphere and red over the other for warning a driver of danger.
