Performance of four different municipal solid waste landfill liner systems, i.e., Subtitle D composite liner system, composite liner system with a geosynthetic clay liner (GCL) instead of low permeability compacted soil, Wisconsin NR500 liner system, and proposed ...

<p>The shrinkage of fabric-supported reinforced geosynthetic clay liner (GCL) panels covered by a geomembrane and left exposed with no overlying soil was openly documented as a potential problem in 2005. Laboratory and field testing has been conducted in an ...

Torsional ring shear tests were performed to evaluate the effect of shear displacement rate on the internal shear strength of a needle-punched geosynthetic clay liner (GCL) under different normal stresses. The test results suggest that the internal shear strength ...

The paper describes a slope failure involving an unreinforced geosynthetic clay liner (GCL) in a municipal solid waste (MSW) landfill liner system. The precise mechanism for the shear movement of the interim slope is not known. However, the significant damage ...

Dry and hydrated specimens of an unreinforced geomembrane - backed geosynthetic clay liner were sheared against a textured geomembrane using a torsional ring shear apparatus to study the shear behavior of geomembrane encapsulated bentonite.
