Field Evaluation of Protective Covers for Landfill Geomembrane Liners Under Contruction Loading Available to Purchase

The performance of landfill geomembrane liner protective cover systems with and without a geotextile is evaluated using field tests. The physical properties of the protective cover soils and the geomembrane liner before and after field testing were determined using laboratory tests. The hydraulic properties of the geomembrane field samples were measured using water vapor transmission (WVT) tests, and the mechanical properties were measured using multi-axial tension tests and wide strip tensile tests. A low mass per unit area geotextile was demonstrated to completely protect the geomembrane in this study.
