Characteristics and Intercorrelations of Index Properties for Cohesionless Gravelly Soils
Several index properties for gravelly soils and factors affecting them are examined, including the unit weight (γ), void ratio (e0, emax, emin), and porosity (n0). A database of 43 sandy and gravelly soils from 36 sites with 137 individual soil samples was employed, along with additional laboratory data, for this examination. It was found that these indices are largely a function of the soil gradation properties, geology, and age. Correlations among these indices and several gradation properties (D50, CU, and angularity) also can be established. Unfortunately, particle shape data are limited, so the influence of this parameter can only be understood qualitatively. However, the developed correlations are useful for estimating the index properties for a wide range of cohesionless sandy and gravelly soils.
