This is a materials specification covering geotextile fabrics for use in subsurface drainage, separation, stabilization, erosion control, temporary silt fence, and paving fabrics. This is a material purchasing specification and design review of use is recommended.
This specification sets forth a set of physical, mechanical and endurance properties that must be met, or exceeded, by the geotextile being manufactured.
In the context of quality systems and management, this specification represents a manufacturing quality control (MQC) document. However, its general use is essentially as a recommended design document.
This specification is intended to assure both good quality and performance of geotextiles used as listed above, but is possibly not adequate for the complete specification in a specific situation. Additional tests, or more restrictive values for the tests indicated, may be necessary under conditions of a particular application.
This specification is based on geotextile survivability from installation stresses. Designers should be aware that the classes in this specification reflect this basic premise. Refer to Appendix X1 of this specification for geotextile construction guidelines.
