Poorly graded
WebHowever, in some cases a more poorly graded filter band may be preferable; for example, if more readily available standard gradations are needed or where onsite filters are used for economy. The design filter band obtained in steps 1 through 12 may be adjusted to a steeper configuration in such cases. Webgraded if Cu > 4 and Cc = 1-3. For the grain size distribution curve shown in Fig. 3.1, D10 = 0.013 mm, D30 = 0.47 mm, D60 = 7.4 mm, Cu = 569 and Cc = 2.3. Therefore, it is a well …

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.
