ASTM D6454-99(2006)

1.1 The test method establishes the procedures for evaluation of the deformations of a turf reinforcement mat (TRM) under short-term compressive loading. This test method is strictly an index test method to be used to verify the compressive strength consistency of a given manufactured geosynthetic. Results from this test method should not be considered an indication of actual or long-term performance of the TRM in field applications.

1.2 Since these TRMs experience multidirectional compressive loadings in the field, this test method will not show actual field performance and should not be used for this specific objective. The evaluation of the results also should recognize that the determination of the short term single plane compressive behavior of geosynthetics does not reflect the installed performance of TRMs and, therefore, should not be used as the only method of product or performance specification.

1.3 The values in SI units are to be regarded as the standard. The values stated in inch-pound units are provided for information only.

1.4 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 to determine the applicability of regulatory limitations prior to use.
