This study is based on experimental data obtained form the soil mixture material (kaolin and sand) with help of triaxial and bender elements' tests. The remoulded soil made from a mixture of sand and kaolin was compacted in layers in order to create two different types of anisotropy. The first set of specimens, homogeneously remoulded, was compacted in such a way that intrinsic anisotropic feature can be observed. The second set was poured in a specific mould in successive layers of sand and kaolin to create a material anisotropy. The triaxial tests will be carried out with local transducers and bender elements measurements. The goal of this experimental project is to determine the evolution of the shear modulus G in function of the mean stress p' applied on the sample.
