WebCrushed gravel and sand with angular particles have higher friction angle due to better degree of interlocking than the bank run gravel and sand with rounded particles. 3. Gradation: Well-graded soils can be compacted to higher density, leading to better degree of interlocking and higher friction angle than that of poorly graded soils. 4.

Soil gradation is a classification of the particle size distribution of a soil. Coarse-grained soils, mainly gravels or sands, are graded as either well graded or poorly graded. Poorly graded soils are further divided into uniformly-graded or gap-graded soils. Fine-grained soils, mainly silts and clays, are classified according to their Atterberg limits.
