AB  - As a product of polymeric materials, geomembranes (GMs) are widely used in 
      engineered systems as impervious barriers due to their low permeability. In this 
      study, a large-scale composite shear test apparatus was developed to investigate 
      the shear behaviors of various GM interfaces. A series of direct shear tests were 
      conducted on GM(-)soil, GM(-)geotextile, and GM(-)concrete interfaces. Two types of 
      high-density polyethylene (HDPE) GMs, a smooth GM and a textured GM, were used to 
      evaluate the effect of GM-texturing on the shear properties of these interfaces. 
      Based on the experimental data, the friction angles and adhesions of GM 
      interfaces were calculated using the Mohr(-)Coulomb criterion. Test results 
      describing the behavior of GM(-)soil and GM(-)geotextile interfaces from the current 
      study were then compared with results from previous studies. The test results are 
      shown to verify the reliability of the new large-scale composite shear apparatus. 
      In addition, this paper presents preliminary experimental results of the 
      GM(-)concrete interface shear tests.
