N2 - Soil classification is intended to help geotechnical engineers anticipate soil properties and behavior. However, the review of soil classification systems used worldwide-within the context of 100 years of experimental data-shows that transition boundaries between various soil denominations are often incompatible with observed behavior. The revised soil classification system RSCS considers attainable packing densities in sands and gravels (a function of their coefficient of uniformity and particle shape), and in the fines component (a function of its plasticity). The overall classification is based on a soil-specific triangular texture chart that is built using gravimetric-volumetric analyses adjusted using extensive soil data. Fines require further analysis when they control either the mechanical or fluid-flow characteristics of the soil; in this case, fines classification recognizes both the plasticity of fines and their electrical sensitivity to changes in pore fluid chemistry.
