Abstract

An airport safety system includes an area of land wherein natural grass has been removed substantially from the grass and artificial turf having a plurality of synthetic fibers, the turf securely installed in the area without the use of a layer of infill dispersed between the fibers. The turf also is capable of absorpting fuel from a fuel spill at or near the area.

Claims (28)

1. An airport safety system comprising:

a runway or taxiway area of airport land wherein natural grass has been removed substantially from the ground; and

artificial turf having a plurality of synthetic fibers, the turf including multiple sections fastened together to form a large, heavy turf mass, the turf mechanically and/or adhesively, securely installed in the area without the use of a layer of infill dispersed between the fibers, the turf delineating at least a portion of one of the taxiway or runway.

2. The system of claim 1 , which includes a growth retarding base beneath the turf.

3. The system of claim 1 , wherein the growth retarding base is selected from the group consisting of: rock, sand, concrete and any combination thereof.

4. The system of claim 1 , which includes at least one membrane positioned beneath the turf.

5. The system of claim 1 , wherein the turf is attached to the runway/taxiway.

6. The system of claim 1 , wherein the turf is attached to a member that is attached to the runway/taxiway.

7. The system of claim 6 , wherein an edge of the runway/taxiway is modified to be positioned against the member.

8. The system of claim 6 , wherein the member is selected from the group consisting of: a solid metal beam, a hollow metal beam, a channel drain, a solid synthetic beam, a hollow synthetic beam, a wood beam, a structural member, and any combination thereof.

9. The system of claim 1 , wherein the turf is attached to the ground via a mechanism selected from the group consisting of: glue, a pinning device, a flexible material secured in place with a base placed beneath the turf, and any combination thereof.

10. A method for increasing safety at airports comprising:

(a) removing natural grass from a safety area at an airport having a runway or taxiway;

(b) installing an artificial turf in the area without the use of a layer of infill, the artificial turf including at least one plastic selected from the group consisting of nylon, polypropylene, and polyurethane and configured and arranged to absorb aircraft fuel from an accident occurring on or near the turf; and

(c) delineating at least a portion of one of the runway or taxiway with the installed turf.

11. The method of claim 10 , which includes placing a growth retarding base beneath the turf.

12. The method of claim 11 , wherein the growth retarding base is selected from the group consisting of: rock, sand, concrete and any combination thereof.

13. The method of claim 10 , which includes positioning at least one membrane beneath the turf.

14. The method of claim 10 , which includes attaching the turf to a runway/taxiway.

15. The method of claim 14 , which includes attaching the turf to a member that is attached to the runway/taxiway.

16. The method of claim 15 , which includes modifying an edge of the runway/taxiway to be positioned against the member.

17. The method of claim 15 , wherein the member is selected from the group consisting of: a solid metal beam, a hollow metal beam, a channel drain, a solid synthetic beam, a hollow synthetic beam, a wood beam, a structural member, and any combination thereof.

18. The method of claim 10 , which includes attaching the turf to the ground via a mechanism selected from the group consisting of: glue, a pinning device, a flexible material secured in place with a base placed beneath the turf, and any combination thereof.

19. An airport runway/taxiway system comprising:

a base located adjacent to a taxiway; and

an artificial turf glued to the base and installed without an infill material, the artificial turf including at least one edge defining at least a portion of an edge of the taxiway to help delineate the taxiway.

20. The airport runway/taxiway system of claim 19 , wherein the base includes a material selected from the group consisting of: rock, crushed rock or concrete.

21. The airport runway/taxiway system of claim 19 , the artificial turf displaying advertising.
