This paper is about laboratory measurement of internal and interface shear strengths of geosynthetic clay liners. Test apparatus, gripping/clamping, hydration, consolidation, shear displacement and post-test measurement are also addressed.

This paper describes a slope failure in a municipal solid waste landfill, with lateral and vertical displacements of up to 275 and 61 m, respectively. To facilitate the analyses, this paper investigates shear strength of municipal solid waste using field and laboratory test results and back-analysis of failed waste slopes.

This article briefly describes the shear behavior of flexible geomembrane/nonwoven geotextile interfaces. In addition, a database of PVC, HOPE and VFPE geomembrane/ nonwoven geotextile interface strengths is presented that can be used for comparison purposes.

Dry and hydrated specimens of unreinforced geomembrane backed geosynthetic clay liners were sheared against a textured geomembrane to study shear behavior of the geomembrane encapsulated bentonite and results were discussed in this paper.

This paper analyses the successful performance of exhumed geomembrane liners over more than 29 years.

In general, geomembranes come in two distinct types. The first type is flexible enough for folding, transport to a job-site in large panels, unfolding, and seaming to other panels for field testing. The other type cannot be safely folded and instead ships as rolled goods.
