ASTM D6243-13
Historical Standard: ASTM D6243-13 Standard Test Method for Determining the Internal and Interface Shear Resistance of Geosynthetic Clay Liner by the Direct Shear Method
SUPERSEDED (see Active link, below)
1. Scope
1.1 This test method covers a procedure for determining the internal shear resistance of a Geosynthetic Clay Liner (GCL) or the interface shear resistance between the GCL and an adjacent material under a constant rate of displacement or constant stress.
1.2 This test method is intended to indicate the performance of the selected specimen by attempting to model certain field conditions.
1.3 This test method is applicable to all GCLs. Remolded or undisturbed soil samples can be used in the test device.
1.4 This test method is not suited for the development of exact stress-strain relationships within the test specimen due to the nonuniform distribution of shearing forces and displacement.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.
