1. What is the primary purpose of a soils special inspector?
A. Design foundations
B. Verify soil compliance with approved plans
C. Perform structural analysis
D. Approve building permits
Answer: B
Rationale: The inspector ensures soil-related work complies with
approved plans and specifications.
2. Which test determines soil compaction in the field?
A. Atterberg limits
B. Proctor test
C. Nuclear density test
D. Sieve analysis
Answer: C
Rationale: The nuclear density test measures in-place density
and moisture content.
3. The Standard Proctor test is used to determine:
A. Soil classification
B. Maximum dry density and optimum moisture
C. Bearing capacity
D. Permeability
, Answer: B
Rationale: It establishes the relationship between moisture
content and dry density.
4. Which soil type has the highest permeability?
A. Clay
B. Silt
C. Sand
D. Loam
Answer: C
Rationale: Sand has large particles and voids allowing rapid
water flow.
5. What does the liquid limit indicate?
A. Soil strength
B. Soil plasticity
C. Moisture at which soil changes from plastic to liquid state
D. Compaction level
Answer: C
Rationale: It defines the moisture content where soil begins to
flow.
6. Which test classifies soil particle size distribution?
A. Atterberg limits
B. Sieve analysis
C. Proctor test
D. Consolidation test
Answer: B
Rationale: Sieve analysis separates particles by size.
7. Expansive soils are most associated with:
A. Sand
B. Gravel
, C. Clay
D. Silt
Answer: C
Rationale: Clay minerals expand and shrink with moisture
changes.
8. What is the purpose of moisture conditioning during compaction?
A. Reduce cost
B. Increase permeability
C. Achieve optimal compaction
D. Prevent erosion
Answer: C
Rationale: Proper moisture ensures maximum density during
compaction.
9. Relative compaction is expressed as:
A. Percentage
B. Ratio
C. Volume
D. Weight
Answer: A
Rationale: It is the ratio of field density to maximum density
expressed as a percentage.
10. Which soil has the lowest bearing capacity?
A. Gravel
B. Sand
C. Clay
D. Rock
Answer: C
Rationale: Clay is compressible and weak compared to other
soils.
