1. The energy ratio in modified Proctor test to standard Proctor test is given by ____.
2. Which of the following is true for pure sandy soils?
3. The 95% saturation and the 5% air voids lines are ____.
4. Which of the following are factors that affect compaction?
5. In a compaction test with increase in compactive effort, ____.
6. Compaction of an embankment is carried out in 500 mm thick layers. The rammer used for compaction has a foot area of 0.05 m2 and the energy imparted in every drop of the rammer is 400 Nm.
