| Abstract: | This paper addresses the study conducted on the performance of landfill liner interface parameters. Interface shear strength
parameters for various combinations of 9 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 for both at dry or optimum moisture condition
and at saturated or wet condition. The interface performance under both conditions were compared to access the material performances.
Tabulated summaries of interface test data under dry or optimum moisture condition (OMO) and saturated or wet condition are
presented in the paper. |
