چکیده مقاله
Particle breakage and crushing of granular materials influence the parameters such as permeability, shear strength, grading curve and porosity As particle breakage continues, stability of structures such as rockfill dams, earth dams, also railway path and road embankments are decreased Shape, size and property of grains, stress path and amount of stress, water content and initial porosity are factors that affect the particle breakage In this research, shape effect and grain size influence on amount of breakage has been studied and different breakage factors have been compared with concentration on grading curve before and after compressive loading in confinement condition Results show that in general, angular and large size materials compared to rounded and small size materials, have high amount of breakages and using Liu breakage factor leads to higher values of breakage than Marshal's and Hardin's
