Description:
The report provides guidance design procedures for the use of geosynthetic materials in hazardous waste land disposal cells. Primary geosynthetic components include flexible membrane liners (FML) used to limit the flow of leachate, and leachate collection and removal systems (LCR) used to monitor for leakage and to remove leachate from the system. Also presented is design guidance for ancillary components including ramps, interior berms, and standpipes. A design procedure is developed for each of the potential failure modes, based on calculation of field service conditions. A Design Ratio (DR) is then calculated as the ratio of the limiting performance of the component, based on laboratory tests, to the actual performance calculated for field conditions. Minimum Design Ratios are recommended for each design procedure. Guidelines are also presented for evaluating the long-term stability of each component. Factors that influence stability are rhelogical properties, aging characteristics, growth of microorganisms, and deformations due to settlement. Chemical compatibility is not considered in the document.
