Tests were performed in the laboratory to assess the impact of freeze-thaw on the hydraulic conductivity of two compacted clays and three alternative barrier materials: a sand-bentonite mixture, three geosynthetic clay liners (GCLs), and three paper mill sludges. Results of laboratory tests performed on the paper mill sludges were compared to results of hydraulic conductivity tests performed in a small-scale field study conducted at the University of Wisconsin-Madison. The small-scale field study consisted of compacting paper mill sludge in large PVC pipes and measuring their hydraulic conductivity before and after exposure to freeze-thaw. Tests were also performed on the paper mill sludges to determine how effective stress and permeation time affect hydraulic conductivity.
