Soil Classification and Identification (With Diagram)

2  · Coarse grained soil may be described as well graded, poorly graded or gap graded. A soil is said to well grade if it has a good representation of all grain sizes. If the soil grains are approximately of same size, then the sample is described as poorly graded. A soil is said to be gap graded if the intermediate grain sizes are absent.
