Description

ASTM D7748-12

Historical Standard: Standard Test Method for Flexural Rigidity of Geogrids, Geotextiles and Related Products

ASTM D7748

Scope

1.1 This test method covers the measurement of stiffness properties of geogrids, geotextiles and geogrid-geotextile composites all of which are referred to as geosynthetics within this standard. Bending length is measured and flexural rigidity is calculated through use of the cantilever test procedure.

1.1.1 This test method employs the principle of cantilever bending of the geosynthetic under its own mass.

1.2 This test method applies to geogrids, geotextiles and geogrid-geotextile composites.

1.3 This test method is for manufacturing quality control purposes only, to ensure uniformity and consistency of flexural rigidity for a specific product from roll to roll and lot to lot.

1.4 The values stated in SI units are to be regarded as the standard. The U.S. customary units may be approximate.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
