A 1.5 m thick strata of sand has a dry unitweight of 15
kN/m3. A contractor passes a vibratory roller over this strata, whichdensifies it and increases its dry unit weightto 16.5kN/m3.
Compute its new thickness.
Hint: consider 1 m x 1 m column of soil.

Expert Answer

Step 1

To determine: The new thickness.

Step 2


Given information:

The initial thickness of sand is 1.5 m.

The initial dry unit weight is 15 Kn/m3

The final dry unit weight is 16.5 Kn/m3

Step 3


Suppose, the new thickness is  x.

Since, ...
