Abstract: Granular materials forming part of the structural elements for civil engineering, structures such as road embankments, the base of pavement and foundations. . . Among these materials, there are those where the grains have a brittle behavior crushing It is, therefore important to study the crushing phenomenon of granular materials, because we need to better understand the behavior of this type of materials and provide information on the crushing evolution. The current work is an experimental study of the granular materials behavior subjected to crushing phenomenon. The expanded clay was chosen as a model material thanks to its brittle crushing behavior toward compressive forces. The study of this phenomenon can be very helpful to understand the soils behavior toward several types of loading. Uniaxial and triaxial compression tests were made to understand the effect of crushing on the grain size distribution, soils frictional properties and mechanical behavio
