Strength Testing of Geotechnical Fabrics
A review was carried out of manufacturing methods for geotechnical fabrics and tests to define their load-extension properties. Some fabrics have complex three-dimensional structures and most are unlikely to be uniform or isotropic. Current test methods do not enable the load-extension behavior to be studied while the fabric is subjected to the normal compressive stresses acting through soil when the fabric is in service. It was judged that data from such tests might not be suitable for design purposes and of current test methods the simple uniaxial stress test appeared to be the most appropriate for quality control work. The results of a series of uniaxial stress tests using BIDIM needle punched fabric indicated that the minimum dimensions of test specimens should be 100 mm (long) and 200 mm (wide).
