This is a materials specification covering geosynthetics for use in subsurface drainage@ separation@ stabilization@ erosion control@ temporary silt fence@ paving@ and soil (walls and slopes). 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 geosynthetic 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 geosynthetics used as listed in Section 1.1@ but is possibly not adequate for the complete specification in a specific situation@ especially in reinforcement applications. Additional tests@ more restrictive values for the tests indicated@ or values based on project specific design may be necessary under conditions of a particular application. Minimum strength values provided in this specification are based on geosynthetic survivability from installation stresses. Designers should be aware that the classes and/or property requirements in this specification reflect this basic premise. Refer to Appendix X1 for most geosynthetic construction guidelines.
