<p>A review of 92 heap leach projects from 15 countries provides a starting point for a series of experiments, at 22 &deg;C and a vertical pressure of 2000 kPa, to examine short-term puncturing and the development of geomembrane strains that could affect longer-term ...

<p>For the last three decades, high density polyethylene (HDPE) geomembranes (GMBs) have played a crucial rule as the primary barrier in municipal solid waste (MSW) landfills. In parallel, there have been extensive investigations into the service life of HDPE ...

<p>A performance-based methodology for seismic analysis and design of the geosynthetic elements of waste containment systems, including landfills and heap leach pads, has been developed. The methodology offers a rational alternative to the current state of ...

The use of fabricated geomembranes can facilitate installation of a containment system, closure cell, final cover system, sports turf barrier, floating cover, e.g., over a leachate pond to reduce precipitation and leachate volume, pond liners, e.g., stormwater ...

<p>Several large-scale laboratory tests were conducted on multi interface geomembrane liner specimens to assess damage effects from static pressure, cyclic loading, and large displacement static shear. The specimens consisted of compacted subgrade soil, a ...

<p>The subject of this paper is exposed-geomembrane-lined ponds whose leakage to the environment is highly undesirable. Such ponds are actually quite common in industrialized settings, and they form an important part of the operating infrastructure of many ...

<p>Heap leaching is one of several leaching methods (in-situ leaching, dump leaching, pressure leaching and tank leaching) whereby metal and other ores are leached with various chemical solutions to extract valuable minerals. Commonly HDPE is used in the pad ...

<p>The shrinkage of fabric-supported reinforced geosynthetic clay liner (GCL) panels covered by a geomembrane and left exposed with no overlying soil was openly documented as a potential problem in 2005. Laboratory and field testing has been conducted in an ...

In summary, the Centerville Neighborhood Revitalization Plan includes Five Star Rated row homes, duplexes, and stacked town homes, a solar energy system to power common areas and a state of the art stormwater management system to protect against flooding and ...

<p>A database of 534 large-scale direct shear test results was assembled in this study to evaluate the interface shear strength between geosynthetic clay liners GCLs and geomembranes GMs . The tests were conducted between 1992 and 2003 by a single independent ...
