Expert Answer

Step 1

D10, D30, D60 refers to:

D10 = particle size (diameter in mm) at which 10% of soil mass finer than the size.

D30 = particle size (diameter in mm) at which 30% of soil mass finer than the size.

D60 = particle size (diameter in mm) at which 60% of soil mass finer than the size.

Step 2

It can be easily be understand by sieve analysis chart. For example...
