WebCoarse soils. Typical grading curves. Both the position and the shape of the grading curve for a soil can aid its identity and description. 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) WebFeb 7, 2024 · Well graded coarse-grained soil contains a good representation of all particle sizes from largest to smallest, with #12 percent fines.
