Dimensional Stability of Geosynthetic Clay Liners in Landfill Applications
… related to the dimensional stability of geosynthetic clay liners (GCLs) in landfill applications. Multiple occurrences of panel separation of overlap seams in GCLs have been documented; however, explanation for the relative contribution of various mechanisms causing shrinkage has been …

Development and Use of Moisture-Suction Relationships for Geosynthetic Clay Liners
… determine the moisture-suction relationships of geosynthetic clay liners (GCLs). Moisture-suction relationships were determined by combining suction data from pressure plate tests, contact filter paper tests, and relative humidity tests, then fitting water retention curves (WRCs) to the data. …

Selected factors affecting measurement of the hydraulic conductivity of geosynthetic clay liners
Geosynthetic clay liners (GCLs) are thin (~7 to 10 mm), factory manufactured hydraulic barriers typically comprising a layer of sodium bentonite sandwiched between two geotextiles. Upon hydration and permeation with water at low effective stress (σ´) (e.g., typically ≤ ~30 kPa [4 psi]), the …

A novel direct shear apparatus to evaluate internal shear strength of geosynthetic clay liners for mining applications
The use of geosynthetic clay liners (GCLs) in engineering practice has grown extensively over the past three decades due to application of this material containment applications such non-hazardous solid waste, residential and commercial wastewater management, roadways, and other civil engineering …

Investigation of Temperature, Solution Strength, and Applied Stress Effects on Cation Exchange Processes in Geosynthetic Clay Liners
… exchange processes in sodium bentonite (Na-B) geosynthetic clay liners (GCLs). The test program was intended to determine if the variables of temperature, solution strength, and applied stress had beneficial or detrimental effects on the engineering behavior of Na-B GCLs in municipal solid …

Field Performance of Exposed Geosynthetic Composite Liner Systems
Geosynthetic clay liners (GCL) overlain by a geomembrane (GMB) in a geosynthetic composite liner system in landfill liner and other waste containment applications can be left exposed for weeks, months, or in some extreme cases, even years. Three known consequences of leaving a GMB-GCL composite …

Comparison of shear strength properties of textured polyethylene geomembrane interfaces in landfill liner systems
… shear strength between geomembranes and geosynthetics is a critical factor governing the stability of slopes that incorporate geosynthetics. In order to better characterise the shear properties of geomembranes, a wide-range of shear strength friction measurements were conducted. This …
