Abstract: Four organic chemicals over a range of concentrations were permeated through compacted specimens of kaolinite and illite‐chlorite. Permeability tests were performed in both rigid and flexible‐wall permeameters. Soil index ...

Abstract: In regions dominated by high-carbonate aggregates, landfill owners are faced with using alternative materials for leachate collection systems. Expanded clay and shale, known as lightweight aggregates, contain essentially ...

Abstract: A pilot scale field test was conducted to demonstrate the feasibility of using prefabricated vertical drains (PVDs) for in-situ point extraction of benzene, toluene, ethylbenzene, and xylene (BTEX) under vacuum. Results ...

Abstract: Asphalt concrete has been used for low permeability barriers in numerous applications over many centuries. In recent times, asphalt concrete barriers have been used for waste containment applications. The hydraulic ...

Abstract: Slender recycled plastic pins (RPPs) can be used to stabilize earthen slopes by driving the RPPs into the face of the slope to intercept the sliding surface and “pin” the slope. The RPPs will be subjected to lateral (bending) ...
