ABSTRACT:
Overlay protection plate apparatus and method are provided to protect partially embedded light fixture supports for airport inset lights for runways, taxiways, or other aircraft ground traffic areas. The overlay protection plate apparatus and method provide protection against paving material entering the light fixture support during airport paving operations. Novel plate locating means and method locate the position of the overlay protection plate after the airport paving operations have covered over the overlay protection plate. Novel plate withdrawal means remove the covered overlay protection plate together with the pavement cover in substantially one piece over the overlay protection plate.
