Abstract	The geotechnical and geochemical properties of sewage sludge from Kaunas city, Lithuania, were investigated to assess whether it could form a low permeability landfill cover. New sludge, sludge stored or kept in the atmosphere and old sludge were studied. It was found that over time the strength of the sewage sludge increased due to self-consolidation and destruction of organic material. The concentration of metals in the sewage extract was considerably lower than in the landfill leachate. It was concluded that if kept in an open polygon for 1–2 years, the sewage sludge can be used as a low permeability landfill cover.Les propriétés géotechniques et géochimiques de boues résiduaires d’assainissement de la ville de Kaunas (Lituanie) ont été étudiées afin d’évaluer si elles pouvaient être utilisées comme couches de faible perméabilité en couverture de remblais. Des boues récentes, des boues placées en stockage ou exposées à l’air et des boues anciennes ont été étudiées. Il a été trouvé qu’avec le temps la résistance de ces boues augmentait du fait de leur consolidation et de la transformation de la matière organique. Les concentrations métalliques mesurées dans ces boues étaient considérablement plus faibles que dans le lixiviat du remblai. Il a été conclu que les boues de décantation conservées à l’air libre pendant 1–2 ans pouvaient être utilisées comme couverture de faible perméabilité pour des remblais.
