Abstract: Post-construction wetting of fills can cause swell or compression, depending on soil composition and stress conditions just before wetting. The various factors affecting swell/compression of compacted cohesive soils are studied, and the steps in analyzing one-dimensional heave/settlement of compacted fills are described. Limitations of the analysis, and recommendations for reducing fill settlement are presented.
