The vast majority of unsaturated soil research is completed on compacted soils. Due to ease of laboratory testing, specimens are typically prepared dry of optimum and often with high void ratios (low dry density) to capture the phenomena of collapse. Compacted soils have significant impacts on infrastructure, but the inherent effects of structure within each sample are difficult to differentiate from the effects of suction (and degree of saturation) in the laboratory. Although significant advances have been made with techniques such as MIP and ESEM. The difficulties of producing and unsaturated sample from slurry have largely limited the amount of published literature on samples reconstituted from slurry. In this paper, the available published data sets of Jennings and Burland (1962), Vicol (1990) and Cunningham (2000) are reviewed. Predictions of the volume change behavior are then made.
