THE USE OF FILTER FABRIC AS A SUBGRADE RETAINER. FINAL REPORT

This project was designed to study the use of filter fabrics as a subgrade retainer, specifically on the construction of a highway (Florida S.R. 80 Relocated) over organic material in Palm Beach County, Florida. The objectives of the project were: (1) to evaluate and compare the construction techniques using three different types of filter fabric to separate the local embankment material from the foundation organic soil; (2) to evaluate the long-term performance of embankment construction using filter fabric over organic soil; and (3) to compare the cost of the two construction techniques, one using filter fabric and the other conventional. This is the final report on this project.
