The strength characteristics of the sand and gravel are influenced by the size of the grains, their distribution and packaging. The theoretical approach states that the sand angle of internal friction decreases if the uniformity coefficient increases. There are insufficient data for gravel correlation between the uniformity coefficient and the angle of internal friction. Consolidated drained triaxial compression tests (CD) were conducted to determine the strength parameters of remolded sand and gravel samples. These samples were classified as sands and gravels. The optimal water content and density were determined by standard Proctor compaction test and used for these samples. Consolidated drained triaxial compression test gives more reliable data that idealize the soil behavior in the real situation. Three different confining pressures of 20, 50 and 70 kPa were applied to restore horizontal stresses for the soil specimens imitating embankment behavior affected with traffic load. The results indicate that the sand angle of internal friction decreases if the uniformity coefficient is increased. The gravel angle of internal friction does not correlate with the uniformity coefficient.
