Safety improvements of airport runways and taxiways are achieved by providing a flexible, water-impermeable surfacing material (14) on a compacted soil base directly adjacent to an edge of airstrip shoulders (12). A synthetic grass surface (30) is provided on the area beyond the surfacing material (14) 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 (14) and will be trapped by the synthetic grass (30), thereby minimizing foreign object damage to aircraft engines, particularly to those overhanging engines which extend well beyond the existing runway and taxiway shoulders.

L'invention concerne des améliorations se rapportant à la sécurité des pistes et voies de circulation d'aéroports, apportées grâce à la mise en place d'un matériau de revêtement (14) souple imperméable à l'eau sur un support de terre compactée jouxtant directement un bord d'accotements de pistes d'aterrissage (12). Une surface de gazon synthétique (30) est aménagée sur l'aire située au-delà du matériau de revêtement (14), de sorte que des corps étrangers, tels que des particules éparses des matériaux d'accotement des pistes d'aterrissage, soient projetées par le souffle des réacteurs à travers la texture relativement lisse du matériau de revêtement (14) et piégées par le gazon synthétique (30), ce qui réduit au minimum les dommages pouvant être causés par des corps étrangers aux moteurs d'avion, en particulier les moteurs en porte-à-faux qui débordent largement les accotements des pistes et voies de circulation.
