With very weak subgrades, it is often beneficial
to combine the benefits of both separation and
stabilization.
A stabilization geotextile facilitates construction over

Design for Stabilization
The design of geosynthetic-reinforced unpaved
roadways has been simplified into design charts
that relate aggregate thickness requirements to a
range of subgrade strengths, based on standard
highway design loading and various allowable
rut depths.
