Estimation of the shear strength of heterogeneous granular soils with matrix

The determination of the mechanical properties of soils containing particles larger than the allowable size by standard laboratory equipment is problematic. It is indeed necessary to eliminate the coarsest fraction to carry out the tests, which poses a problem of representativeness of the results at...
