Performances of Landfill Liners Under Optimum Moisture Conditions (original) (raw)

This paper addresses the study conducted on the performance of landfill liner interface parameters. Interface shear strength parameters for various combinations of 12 different lining materials were studied and presented in this paper. This comprehensive testing program covers the interfaces between: 1) soil and compacted clay liner (CCL), 2) geomembrane (HDPEs or PVC) and soil, 3) geosynthetic clay liner (GCL) / CCL and soil, 4) geomembrane and geotextile, 5) geotextile and soil, 6) geotextile and GCL / CCL, and 7) geomembrane and GCL / CCL. The experiments were conducted under optimum moisture condition. Tabulated summaries of interface test results under optimum moisture condition are presented in the paper.
