WebGeometrical grading characteristics can be determined also from the grading curve. ... Some typical grading curves are shown in the figure: A - a poorly-graded medium SAND (probably estuarine or flood-plain alluvium) B - a well-graded GRAVEL-SAND (i.e. equal amounts of gravel and sand) C - a gap-graded COBBLES-SAND WebThis is called poorly graded soil. Curve II represents a soil in which the particles are distributed over a wide range, termed well graded. A well graded soil will have a uniformity coefficient greater than about 4 for gravels and 6 for sands, and a coefficient of gradation between 1 and 3 (for gravels and sands).

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. A well-graded soil is a soil that contains particles of a wide range of sizes and has a good repres…
