Geotextiles provides effective stabilization and critical subsoil /
base course separator for paved surfaces and also stabilize and retain
aggregate for unpaved surfaces , such as parking, loading lots, roads, airport
runways, …etc.as shown in figure (I.5) (16)

Subgrade stabilization has always been a problem to the railroads. Due
to heavy dynamic load resulting from train traffic, the stony ballast is very
often contaminated by rising fine particles from the underlying soil, which
leads to deformation of the ground which eventually causes a gradual decrease
in the bearing capacity of the upper structure. (17)
Geotextiles
used in railroad stabilzation reduce maintenance and extend the track’s service
life. They also prevent the loss of costly ballast , reduce rail deformation ,
and increase the ballast’s loadbearing capacity. (8)
