Geotextile-Roads

Geotextiles provide three main functions to the roads: 
Separation
Woven Geotextile and non woven Geotextiles provide long-term separation of the aggregate base from the subgrade soil. By separating these two materials, the Geotextile maintains the original thickness of the roadway aggregate. This is the most important Geotextile function for roads, particularly where the road is being constructed on weak subgrade soils.
Filtration and Drainage
Geotextile allows the ground water to pass into the subsurface drain without eroding the soil and helping the ground from deterioration making the life of the roads very long.
Stabilization
Higher strength PP and polyester woven geotextiles provide strength to the roads thus making it increment in the effective bearing capacity of low strength sub-grade soils and increase the life of the roads.
