ASTM D 5514 : 1994 : R2001

1.1 This test method evaluates the stress/time properties of geosynthetics by using hydrostatic pressure to compress the geosynthetic over synthetic or natural test bases consisting of manufactured test pyramids/cones, rocks, soil or voids.

1.2 This test method allows the user to determine the relative failure mode, points of failure for geosynthetics, or both.

1.3 This test method offers two distinct procedures.

1.3.1 Procedure A incorporates manufactured test pyramids or cones as the base of the testing apparatus. Procedure A is intended to create comparable data between laboratories, and can be used as a guide for routine acceptance test for various materials.

1.3.2 Procedure B incorporates site specific soil or other material selected by the user as the test base of the testing apparatus. Procedure B is a method for geosynthetic design for a specific site.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.

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.
