Q: Where can I find literature on the useful service life of nonwoven geosynthetic fabrics installed in soils? Thank you.
A: Nice to hear from you and thanks for your question in regard to the service life of nonwoven geotextiles.
Below is a reference that I think is very good. In addition, I have exhumed a TYPAR roadway separation installation from 1972 every 10 years, and it is still going very strong.
