Description:
The geotechnical characteristics of compacted soils used by the Prairie Farm Rehabilitation Administration in earth embankments were correlated with easily obtained soil properties.Relationships were established between Standard Proctor maximum density and optimum water content versus liquid limit for clay soils. In addition, a relationship was established to determine the Standard Proctor maximum dry density and optimum water content using the results from the one-point Proctor test for clay, and sand and silt soils.Effective shear strength parameters and consolidation characteristics of compacted samples were related to liquid limit, water content, and dry density. The results of field and laboratory measurements of pore pressure were used to relate the pore pressure coefficients U/σ3 and U/σ1 to the deviation of water content from optimum water content and applied stress. A relationship was established between embankment compression and embankment height using field measurements of embankment settlement.The data suggest that similar geotechnical characteristics will be obtained for laboratory and field compacted alluvial and glacial soils when they are placed with Standard Proctor compactive effort at similar water contents, densities, and liquid limit. In this paper 'alluvial clay' is used to describe clays deposited in lacustrine or fluvial environments and 'glacial clay' is used to describe clays deposited by a glacier.
