Improved Radio Frequency Pavement Identification Tag

      Described is a hardware implementation whereby radio frequency
(RF) pavement identification tags are provided with a stability
collar.

      In prior art, RF pavement tags, typically installed in steel
mill slag roadbeds, have had a tendency to shift position causing
poor and/or no read conditions.

      The concept described herein improves on the pavement tag
design by utilizing a concrete stability collar with a receptacle
hole for the pavement tag.  The collar, approximately eighteen inches
in diameter and four inches thick, provides lateral and vertical
stability to the RF tag so as to allow its position to be maintained,
thereby enabling the reader to function as expected.
