  • Patent number: 4127346
    Abstract: A traffic control marker for use with an asphaltic pavement including a rigid plate having a top indicating surface and a bottom surface adapted for contact with the asphaltic pavement and a continuous rigid flange which depends from the peripheral portion of the rigid plate. The continuous rigid flange is adapted for embedment in the asphaltic pavement to a depth at which the top indicating surface of the rigid plate is flush with the top surface of the surrounding asphaltic pavement. The rigid plate is provided with vent holes to assure uniform contact between the bottom of the rigid plate and the asphaltic pavement when the traffic control marker is installed in place. In the preferred form, the continuous rigid flange depends from the rigid plate at an angle of about 90.degree. to the plane of the rigid plate, but may depend at other angles if greater gripping action of the continuous rigid flange is desired.
