ESTIMATING FIELD HYDRAULIC CONDUCTIVITY OF COMPACTED CLAY. TECHNICAL NOTE

The authors present findings of hydraulic conductivity tests conducted in the field and laboratory for soils collected from 11 compacted clay test pads or liners. Field tests were performed with sealed double-ring infiltrometers to define the field-scale hydraulic conductivity. Laboratory tests were performed on large undisturbed block specimens and small specimens collected in thin-wall sampling tubes. Results of the laboratory tests at low effective stress indicate that the hydraulic conductivity of the block specimens was similar to field-scale hydraulic conductivity at each site. The authors conclude that a conservative estimate of the hydraulic conductivity of these soils at various effective stresses can be made provided the field-scale hydraulic conductivity is known.
