Classify the following inorganic soil (provide both group symbol and group name) according to the Unified soil Classification System.

Percent passing no. 4 sieve = 46

Percent passing no. 200 sieve = 4

Coefficient of gradation = 2.78

Uniformity coefficien t= 4.3

Liquid Limit (LL) = NA

Plastic Limit (PL) = NA

classify this soil based on unified soil classification system and write down just its group symbol and group name.

Explanation / Answer

The soil is GW or in other words-well graded gravel.

Since percent retained on no.4 sieve=100-46=54%,which is greater than 50%,it is gravel.

Amount of soil passing no.200 sieve is less than 5%.Hence,it is well graded gravel.
