Standard Test Method for Measurement of Index Flux Through Saturated Geosynthetic Clay Liner Specimens Using a Flexible Wall Permeameter

Test Method Title

Standard Test Method for Measurement of Index Flux Through Saturated Geosynthetic Clay Liner Specimens Using a Flexible Wall Permeameter

Reference Number

ASTM D5887

Material

Geosynthetic Clay Liner

Test Property

Index Flux

Description of Test

This test method involves permeation of a 100-mm (4in.) diameter GCL test specimen. The specimen is set up in a flexible-wall permeameter, subjected to a total stress of 550 kPa (80 psi) and a backpressure of 515 kPa (75psi) for a period of 48h. Flow is initiated using deionized water by raising the pressure on the influent side of the test specimen to 530 kPa (77psi). The flux is determined when inflow and outflow are approximately equal (within 625%).
