Hence, application of geosynthetic materials as landfill bottom liners and capping systems has seen a substantial increase over the past few decades. The present work emphasizes the shear strength of geocomposite clay liner (GCL) and geomembrane interface in landfills. Using direct shear tests, shear stress was measured as a function of normal load to determine the values of interface frictional angle and adhesion of the geosynthetic interface. The variation of interface friction angle and shear strength for both frozen and unfrozen samples was observed. In the current work, we tried to simulate the conditions in a landfill of northwest Ohio. We conducted 66 direct shear tests on 4 different types of GCL’s at 5 different moisture contents subjected to 3 different normal stresses 1.038 psi, 2.076 psi, and 4.152 psi which represented the general normal pressure range applied to the capping system in most of the landfills in frozen as well as unfrozen conditions. We observed that the shear stress values of the samples in frozen and unfrozen conditions had no significant difference. Therefore, it is concluded that the effects of freezing temperature on the geosynthetic interface in a capping system of a landfill is negligible.","abstract_html":"In modern days, municipal and hazardous waste containment facilities i.e., landfills are performance standard designed, well-engineered, operated, and monitored in compliance with federal regulations in 40 CFR Part 258 (Subtitle D of RCRA), or equivalent state regulations.
