Permeability Control of Compacted Landfill Liners and Covers
The most common soil barriers used to contain waste units consists of fine grained clayey soils.For these soil barriers,the permeability is the parameter of primary concern.This parameter can be determined either directly by performing in situ tests or indirectly through the check of the dry unit weight and water content frequently measured in situ.In fact,the measurement of soil permeability in situ is not an easy task; the permeability test takes long time to perform,and makes difficult any intervention to improve the quality of the soil barrier.Therefore,the simple way to check the permeability of compacted soils in situ is through measuring the dry unit weight and water content.This paper presents a methodology for the study and indirect control of the permeability of soils compacted in situ.According to the quality sought for the soil barrier,this methodology allows laboratory definition of an acceptable zone in terms of the dry unit weight and water content.This zone must be complied with during construction and serves as a criterion for in situ checking of permeability.
