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.

Step 1

**To determine**: The new thickness.

Step 2

**Explanation**

Given information**:**

The initial thickness of sand is 1.5 m.

The initial dry unit weight is 15 Kn/m^{3}

The final dry unit weight is 16.5 Kn/m^{3}

Step 3

Calculation:

Suppose, the new thickness is *x*.

Since, ...
