1.1 This test method is used to determine the unconfined compressive creep characteristics of drainage geotextiles, geocomposites, geonets, or any other geosynthetic associated with drainage at a constant temperature, when subjected to a constant compressive stress.
1.2 This test method is intended for use as an unconfined compressive performance creep test only. For a detailed procedure on how to establish an index test see the EN standard 1897. For performance tests, the specimen shall be subjected to the site-specific liquid and/or the site-specific stress (normal and potentially shear stress).
1.3 Because of the changing nature of the geosynthetic industry, and the wide variety of products already available, this particular test method may have to be slightly modified for unconfined compression creep testing of some products..
