Fine-grained soils are responsible for most site settlements through a time dependent process known as consolidation. The magnitude of consolidation is quantified with three terms: the recompression and compression indices, referred to as the soil's compressibility indices, and preconsolidation pressure. The ideal methods to estimate these parameters are direct measurements from lab or in-situ field tests, other method include estimation from experience or from correlations to soil parameters. This study refines correlations between compressibility indices and index properties as previously researchers and soil mechanics suggest a strong correlation exists. This study also suggests a correlation to CPT parameters as this test is commonly used and has the potential to provide continuous and repeatable compressibility profiles. It was found that compressibility is strongly related to the CPT pore pressure reading for soils with pronounced colloidal properties. It was also found that the correlation to moisture content performed better than all previous recommended models.
