Mechanical behavior of the waste body controls many aspects of landfill lining system design and performance, including stability issues and integrity of the geosynthetic components. The compression behavior of municipal waste is influenced by the properties of the individual constituents and on their composition, and particularly characterized by large amounts of settlements which are time-dependant. Mechanical properties of waste are often described by application of soil mechanics principles so that conventional shear or compression parameters can be determined. But data from literature are scarce and show large variations. In this paper test results on the determination of waste compressibility are reported and analyzed.
