Answer 1

Answer #1

As given soil on sieve no. 4 is 90% that is more than 50% . Hence it is coarse grained soil .

As, drive no. 4 have size opening 4.76 mm therefore, the soil have 90% particles more than size 4.75 mm . Therefore it is coarse grvel.

And as given Cu is less than 4 i.e 3.9 Hence , it is poor graded gravel .

Please upvote as a gesture of appreciation.

If any doubt kindly comment. Thank you.
