The Coastal Plain soils of Virginia generally comprise recent marine and fluvial deposits. It is widely accepted that grain size, plasticity, and water content of the soil are indices that can be used to geotechnically characterize fine-grained soils. The objective of this study was to determine whether the soils from a specific geologic formation have consistent or similar index properties. The data from a previously performed extensive field exploration in the Coastal Plain soils of Virginia were used in the study. The data were divided by local geology and subdivided into separate groups based on the soil fines content (FC) and density. Mean values for water content, Standard Penetration Test N-Value, Atterberg limits, FC, and pocket penetrometer tests were then determined for each geology. The statistical analysis of soil index properties was performed for soils in different formations. The results allow better identification of soils in different formations from index property testing.
