Abstract

The hydraulic conductivity of a scrim reinforced nonwoven thermal locked geosynthetic clay liner (GCL) with respect to both de-aired distilled water and arctic diesel (jet fuel) are examined for different numbers of freeze and thaw cycles. The hydraulic conductivity of jet fuel is found to be about one order of magnitude smaller than that for de-aired water. Increasing numbers of freeze and thaw cycles, did not significantly change the hydraulic conductivity although the permittivity with respect to water decreased. The intrinsic permeability of the GCL permeated by jet fuel increased slightly with an increasing number of freeze-thaw cycles. It is shown that under the conditions examined, the GCL performed very well.
