Abstract: In this paper an experimental study of the measurement of stability angles for naturalgranular piles is presented. The critical dimensions needed for the determination of the anglesaccording to the particle characteristics are established. The material used in the experiments wascommonly coarse and fine aggregates used in road construction with a wide range of sizes. Grains wereclassified by family size and characterized through shape factors, apparent density and compacity. Theminimum size of the system necessary for measuring the angles of stability was determined dependingon the type of experiment to be performed. Results are discussed in terms of the geometry of thedifferent piles and the size of the system.
