Unified Soil Classification System Wikipedia

The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain size distr

Table 3–1 shows some of the commonly used grade scales for compari-son. Note that the range in size for a particular class of particle may differ from one classification system to another.

Gravel is a mixture of three sizes or types of material: stone, sand and fines.
