Investigation of a clay lined storage pit
… shown on the plans, the presence of the bottom clay liner is questionable. Large depressions and numerous cracks were found in the waste area. Acid contamination of the groundwater and the subsoils exists to a considerable depth. Laboratory tests illustrated the susceptibility of the copperas to …

An Evaluation of Borehole Hydraulic Conductivity Equations and Field Determined Soil Water Characteristic Curves
… to determine the hydraulic conductivity of compacted clay liners (CCLs) are of importance for safe guarding the environment from landfill leachate. Therefore, the methods utilized in the analysis of the Two Stage Borehole (TSB) test, as described in the ASTM D6391-11 (Method A, B, and C) …

Calculating and Limiting Local Strains in Geomembranes From Gravel Indentations
… municipal solid waste landfill base geomembrane liners are investigated with an emphasis on quantifying how strains are obtained and providing methods for limiting long-term local geomembrane strains below allowable levels. This involved the development of new experimental techniques and …

Centrifuge modelling of the behaviour of geosynthetic-reinforced soils above voids
… soil systems such as embankments and landfill liners. Centrifuge modelling of the soil and geosynthetic behaviour was conducted using a trapdoor to simulate the formation of a void in a controlled environment at realistic stress levels. A plane-strain model allowed visual observations of the …

Limiting membrane and diffusion behavior of a compacted sand-bentonite mixture for hydraulic and chemical containment
… diffusive contaminant transport. Additionally, compacted mixtures of Na-bentonite and sand can be an effective and economical alternative to barrier materials consisting only of natural clay (e.g., compacted clay liners) if the use of natural clay is not logistically or economically feasible. …
