Soil MechanicsCompaction TestMEDIUM
Choose the correct answer
A
593 kJ/m³
B
604 kJ/m³
C
2674 kJ/m³
D
1200 kJ/m³
Correct Answer
A. 593 kJ/m³
Why is this the answer?
Standard Proctor compaction energy is approximately 593 kJ/m³. The calculation is (3 layers * 25 blows * 2.5 kg * 9.81 m/s² * 0.305 m) / 0.000944 m³ = 593 kJ/m³.
