Experimental Investigation of the Effects of Moisture Levels on Geocomposite Drainage–Geomembrane Interface Shear Behavior
Large-scale direct shear tests compare drainage-geocomposite interfaces with smooth and textured geomembranes at different moisture levels. Texture and wetting affect peak and large-displacement strength, supporting site-specific cap stability testing.

Laboratory Evaluation of Geosynthetic Interface Friction under Low Stress
Summarises laboratory interface friction tests relevant to shallow landfill covers. Failure mode, surface wear, fluid and soil density affect friction, so high-stress test results should not be assumed suitable for low-stress interfaces.
