→Used for determination of the tensile strength properties of geogrids by subjecting strips of varying width to tensile loading.
→It is used for quality control and conformance testing of geogrids.
→Three alternative procedures are provided to determine the tensile strength, as follows:
Method A-Testing a single geogrid rib in tension
Method B-Testing multiple geogrid ribs in tension.
Method C-Testing multiple layers of multiple geogrid ribs in tension.
