Measured Permeability in Stabilized Swedish Soils
Helen ┼hnberg

In connection with a large Swedish research programme concerning different aspects of deep stabilization of soft soils, a number of permeability tests have been performed on certain soft soils stabilized with different type of binder in the laboratory. The permeabilities of the stabilized samples were measured in permeameter tests and in CRS oedometer tests. Although exhibiting a fairly large scatter in results, the tests showed that the permeability changed with time and with the amount of binder. They also showed that the permeability to some extent varied with the type of binder used. Comparisons made with other permeability investigations on stabilized soils have shown both agreement and deviations from the results in the present study. It was found that changes in permeability in the stabilised material to a large extent could be linked to the increase in strength and decrease in water content.
