FILTER FABRICS FOR AIRPORT DRAINAGE

This report provides a general review of fabric experience that applies to airport construction of surface and subsurface drainage installations and develops interim guidance for design, specifications, and installation of filter fabrics. Two fabric applications of surface drainage are considered: (1) between a channel or reservoir slope and the slope protection for scour, erosion, and pipe performance, and (2) silt fences for prevention of stream pollution by sediments in runoff. Three types of subsurface drainage applications are considered: (1) trench drains, (2) separation, and (3) drainage for consolidation of soft soils. A need for long-term correlation of field performance with fabric type, soil type, soil grain size, and hydraulic characteristics is pointed out. Two levels of guidance for the use of fabrics in airport drainage are suggested for use--(1) critical applications where if the design life is long (greater than 15 years), failure of the drainage installation would endanger life or structures, or require expensive maintenance, and (2) noncritical applications for short-life projects or applications that may be easily and inexpensively replaced. Appendix A describes current FAA use of filter fabrics in drainage, and Appendix B provides specific guidance for critical and noncritical use of fabrics under the above-mentioned applications.
