![]() When you properly choose woven and nonwoven geotextiles it will prevent these failures from ever happening and greatly improve the performance of the road. Secondly, the granular aggregate will push into the fine-grained soil decreasing the needed thickness of the aggregate layer. To begin with, fine-grained soils enter into the gaps of the granular aggregate, preventing proper drainage and the aggregate will lose its needed rock-to-rock contact which in turn will greatly diminish the strength of the aggregate support layer and will increase road failure. ![]() (Koerner, 1994).įor paved and unpaved roadways where granular aggregate is placed on fine-grained soils, there are two damaging occurrences that will take place over time without the use of geotextile separator: Geotextile was established as a flexible, porous textile placed between different materials in order for the integrity so the function of both materials can remain intact or be improved upon.
