GEOTEXTILE ENGINEERING MANUAL

This Manual was prepared as a textbook for the FHWA training course "Geotextile Engineering Workshop." The manual was prepared to enable the Highway Engineer to correctly evaluate each application and to properly select, design and construct with geotextiles in transportation applications of filtration, drainage, erosion control, materials separation, and soil reinforcement. The effectiveness of using geotextiles for each application is reviewed, particularly with respect to performance and cost when compared to alternate systems. Specifically covered are: Test methods for determining engineering properties of geotextiles; development of construction specifications; determination of fabric suitability and feasibility as cost effective alternative designs for specific applications; and construction procedures and details.
