An artificial grass surface (10) suited for bordering a runway (12) of an
airfield in order to reduce the presence of birds in the airfield. The
artificial grass surface (10) includes a pile fabric (14) having a
plurality of pile elements (20) extending from a backing mat (18) and
resembling grass. A water barrier (24) is provided for preventing water
from percolating to the compacted soil surface. An infilled particulate
material (22) is dispersed among the pile elements (20). A stabilizer is
provided to resist dislodgment of the infilled particulate material (22)
at the edges of the runways by the thrust of jet engines and to keep the
particulate material (22) in the pile elements (20) when the edges of the
runways are vacuumed to remove silt.
