Standard Practice for Burial and Retrieval of Samples in a Test Pad to Evaluate Installation Effects on Geosynthetic Clay Liners

Importancia y uso:

5.1 The ability to maintain design function (for example, barrier) or design properties (for example, peel strength, chemical resistance, etc.), or both, of a geosynthetic clay liner may be affected by damage to the physical structure of the GCL due to the rigors of field installation. The effect of damage may be assessed by analyzing specimens cut from sample(s) retrieved after installation in a representative test pad. Analysis may be performed with visual examination or laboratory testing of specimens from the control sample(s), and from the exhumed sample(s).

5.2 A uniform practice for installing and retrieving representative sample(s) from a test pad is needed to assess installation damage using project-specific or generally accepted, representative materials and procedures. Damage of a specific grade and type of GCL under specific installation procedures may be assessed with sample(s) exhumed from a full-scale test pad.
