Abstract

A method and apparatus for performing rapid repair of a crater-damaged aircraft runway. The surface level area of the crater is first enlarged to a predetermined rectangular area within which a plurality of concrete tiles of a standard area will fit contiguously to cover the area. The crater is filled with material. The contour of the runway leading up to the area is conformed to by a series of end-to-end scraper blades of widths equal to that of the tiles, the blades are lifted en masse and traveled to an edge of the rectangular area where they are lowered thereinto to a depth below the undamaged surface equal to the thickness of a tile. The device is then traveled to the other end of the area while striking off the fill material to provide a smooth, even surface upon which the tiles are laid.
