The permeability of two soils stabilized with lime when compacted at various molding water contents has been investigated in the laboratory. A poorly graded river sand and sandy silty clay were used. The effect of lime content, curing age, dry density, and type of soil on the permeability were investigated. The addition of lime reduced the permeability of the investigated sand at various moisture contents, while the permeability of the clay increased when compacted at the optimum moisture content. The permeability of all mixtures was found to decrease with curing age. There existed a molding water content for the sand-lime mixture at which the permeability reached a minimum. The permeability of the investigated sandy silty clay increased with increasing lime content at the same dry density.
