In-situ comparison of the performance of clay and geosynthetic clay liners in landfill covering

Abstract

Different capping systems are studied at an experimental MSW landfill, since 1997. Two types of covers, with clay and with geosynthetic clay liner (GCL) are tested and compared in order to study hydrous, thermic and mechanical behaviours. This paper presents the information relative to the comparison between GCL and clay liner performances,
