A given cohesion less soil has emax = 0.85 and emin = 0.50. In the field, the soil is compacted to a mass density of 1800 kg/ m3 at a water content of 8%. Take the mass density of water as 1000 kg/m3 and Gs as 2.7. The relative density (in%) of the soil is
-
- 56.43
- 60.25
- 62.87
- 65.71
Correct Option: D
| P = | 1 + e |
| ⇒ 1800 = | 1 + e |
| ∴ 1 + e = | 1800 |
∴ e = 0.02
| ID = | × 100 | emax - emin |
| = | × 100 | 0.85 - 0.5 |
= 65.714%
