Abstract: The installation of geomembranes (synthetic liners) under deep valley landfills of utility and mine waste presents unique problems. Limited data are available concerning geomembranes beneath large embankments constructed over extended periods of time. Evaluations of slope stability, abrasion resistance and durability under high stresses and slope conditions are generally limited to hypothetical rationale. This paper describes the laboratory testing and engineering procedures used to predict the performance of geomembrane systems beneath coal ash/coal refuse disposal sites in western Pennsylvania.
