1. What is the mass of the hammer in modified proctor test?

[A] 2.5 kg

[B] 3.93 kg

[C] 4.89 kg

[D] 6.1 kg

Answer: Option C


2. Proctor test is performed on the soil for ____.

[A] Grain size analysis

[B] Assessing its shear strength

[C] Assessing its bearing capacity

[D] Assessing its degree of compaction

Answer: Option D


3. The neutral stress is ____.

[A] Transmitted through the points of contact of the interconnected particles of soil

[B] Transmitted to the soil base through the pore water

[C] Independent of the depth of water above the soil mass

[D] Due to weight of soil particles

Answer: Option B


4. The coefficient of permeability does not depend upon ____.

[A] Void ratio of the soil

[B] Duration of flow

[C] Equivalent diameter of the soil grains

[D] Shape of the particle

Answer: Option B


5. Consider the following statements:


  1. Soil with high void ratio has always more coefficient of permeability than the soil with lower void ratio.
  2. Constant head permeability test is used for fine grained soil.
  3. As temperature increases, the coefficient of permeability of soil also increases.
  4. As the specific surface area of soil particle increases, the coefficient of permeability decreases.

Which of these statements are correct?

[A] 1 and 2

[B] 2 and 3

[C] 3 and 4

[D] 4 and 1

Answer: Option C 


Higher the void ratio higher is the permeability.


Constant head permeability test is used for coarse grained soil.
