Soil classification systems help geotechnical engineers anticipate soil properties and provide early guidance for engineering analyses. Current recognize the central role of particle size inherent differences between coarse- fine-grained fractions. However, they adopt fixed boundaries irrespective a broad range fines plasticity shape, disregard distinct thresholds mechanical hydraulic propertie...
