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.

An edge-fastening system for securing an airfield safety arrangement surfacing material in position relative to an airstrip shoulder, the edge fastening system comprising:
- an anchor adjacent the side edge of the airstrip shoulder, said anchor having a head bonded to a longitudinal side edge of said surfacing material;
- and
- wherein said anchor and said shoulder form a fluid-tight seal.
An edge-fastening system for securing an airfield safety arrangement surfacing material in position relative to an airstrip shoulder, the edge fastening system comprising:
- an anchor in the form of an extrusion adjacent the side edge of the airstrip shoulder, said anchor having:
- a head bonded to a longitudinal side edge of said surfacing material;
- and
- a bottom anchoring portion connected to said head;
- and
- wherein said anchor and said shoulder form a fluid-tight seal;
- and
- a sealer between the anchor and the airstrip shoulder.
An edge-fastening system for securing an airfield safety arrangement surfacing material in position relative to an airstrip shoulder, the edge fastening system comprising:
- an anchor in the form of a prefabricated plastic extrusion adjacent the side edge of the airstrip shoulder, said anchor having:
- a head bonded to a longitudinal side edge of said surfacing material;
- and
- a bottom anchoring portion connected to said head via an upstanding leg portion;
- and
- wherein said anchor and said shoulder form a fluid-tight seal;
- and
- wherein said anchor is partially embedded in expansion foam;
- and
- further comprising a sealer between the anchor and the airstrip shoulder.
