Abstract: 

Granular media are non continuous media that their structure is made of in touch granules with different shapes and sizes. The materials used in unstabilized subgrade and pavement layers are such media. Study about the behavior of granular materials at the loading time needs to analyze variants in two microscopic (local) and macroscopic (global) levels. The behavior of granular materials is influenced by their geometrical structure as well as micromechanical variants. Nowadays numerical simulation is one of the methods which is used for studying the granular media. In this paper by numerical simulation of biaxial pressure besides of showing of variation of geometrical and mechanical of environment during loading it will compare the result of numerical and experimental simulation.
