Geosynthetics in roads and pavements

 

Geotextile Properties 

Depending on the gradation of the bank soil, 

either a nonwoven or a woven geotextile can be 

selected.  AASHTO M288 provides guidance on 

selecting the appropriate geotextile properties.

Site Preparation 

The site should be prepared in accordance with 

good engineering practices.  The slope or bank 

should be graded smoothly and be free from 

stumps or debris.  The surface should be 

compacted. Any pockets of soft soil should be  

removed and replaced with compacted earth 

material to provide a consistently uniform and 

strong, stable surface.
