Roadway Geotextile Fabric

Geotextiles provide this critical permeability as they filter or keep the fines from migrating upward into the aggregate. Maintaining drainage of the aggregate base and sub grade soil is very important to prevent accelerated failure of the support system. A geotextile also allows the use of more......

Geotextiles provide this critical permeability as they filter or keep the fines from migrating upward into the aggregate. Maintaining drainage of the aggregate base and sub grade soil is very important to prevent accelerated failure of the support system. A geotextile also allows the use of more open, free draining aggregates instead of those with fines, which are weakened by moisture and are freeze-thaw sensitive.

Geotextiles are used in reinforcement through mechanisms of restraint or confinement, friction, membrane effect and local reinforcement.

Geotextiles also play a major role in construction of paved roads over areas having high ground water table.
