Functions:
− Separation
Paved and unpaved roadway applications are stabilized when the geotextile is placed at the subgrade/aggregate interface.
− Filtration
Nonwoven geotextiles provide superior hydraulics property and soil retention, making them ideal for filtration in subsurface drainage systems
− Cushioning
The nonwoven geotextile lessens the impact to the road structure when placing at the subgrade/aggregate interface.
