722.00General Geotextile Property Requirements This is a mat erials specification
covering geotextile fabrics for use in stabilization/reinforcem ent, drainage, erosion control and separation applications. This specification sets forth a s et of physical, mechanical and endurance properties that must be met, or exceeded, by the geot extile being manufactured. This specification is intended to assure both good quality and performance of geotextiles but is possibly not adequate for the c omplete specification in a sp ecific 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 geote xtile survivability from installation stresses. This Section is intended for use in con junction with Section 620 - Geotextiles. Table 1 provides strength properties for three geotextile cla sses. The geotextile shall conform to the properties in Table 1 based on the Geotext ile Class required in the application specific sections which follow. All Table 1 property values represent Minimum Average Roll Va lue (MARV) in the weakest principal direction and shall meet or exceed the va lues stated below. The geotextile properties required for each Class are dependent on geotextile elongation.
