ABSTRACT:
Safety improvements of airport runways and taxiways are achieved by providing a flexible, water-impermeable surfacing material on a compacted soil base directly adjacent to an edge of airstrip shoulders. A synthetic grass surface is provided on the area beyond the surfacing material so that foreign objects such as loose particles of the airstrip shoulder materials will be driven by jet blasts and run-off across the relatively smooth texture of the surfacing material and will be trapped by the synthetic grass, thereby minimizing foreign object damage to aircraft engines, particularly to those overhanging engines which extend well beyond the existing runway and taxiway shoulders.
