Question
![**Problem Statement:**
A granular soil with the following properties:
- Specific Gravity (Gs) = 2.70
- Maximum void ratio (e_max) = 0.880
- Minimum void ratio (e_min) = 0.520
This soil is compacted to a moist unit weight of 112.2 psf at a moisture content of 11%.
**Question:**
What is the relative density of the compacted sand?
*Note:* The relative density (Dr) is a measure of the compactness of a granular soil and is calculated using the void ratios. The formula for relative density is:
\[ Dr (\%) = \left( \frac{e_{max} - e}{e_{max} - e_{min}} \right) \times 100 \]
Where:
- \( e \) is the in-situ void ratio of the compacted soil.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F24dbfb66-daf6-4b8e-a748-b5c870ef5592%2F92687c71-79b0-4d33-a21d-2ba463f99697%2Fx5zesuk_processed.jpeg&w=3840&q=75)
