Success Exam) Graded A+
1. During subgrade preparation, the inspector observes pumping under roller
loads. What is the most appropriate action?
A. Continue compaction until pumping stops
B. Add water to stabilize the soil
C. Remove and replace unstable material
D. Increase roller speed
Answer: C ✓
Pumping indicates excess moisture and instability in the subgrade. The correct
corrective action is to remove and replace the unsuitable material to achieve
proper bearing capacity.
2. What is the primary purpose of a proof roll?
A. Measure density
B. Identify weak areas in subgrade
C. Smooth the surface
D. Apply final compaction
,Answer: B ✓
Proof rolling is used to detect soft spots and assess uniform support before
pavement placement.
3. A nuclear density gauge measures which two primary properties?
A. Moisture and temperature
B. Density and moisture content
C. Compaction and strength
D. Air voids and permeability
Answer: B ✓
The gauge determines in-place density and moisture content, critical for
compaction control.
4. When inspecting aggregate base, which gradation issue is most critical?
A. Slight excess fines
B. Uniform particle size
C. Segregation
D. Color variation
Answer: C ✓
Segregation causes non-uniform strength and poor load distribution in the base
course.
5. What document defines acceptable material quality for construction?
A. Daily report
B. Project schedule
C. Specifications
D. Weather log
, Answer: C ✓
Project specifications outline material requirements, tolerances, and acceptance
criteria.
6. What is the main function of prime coat?
A. Seal asphalt surface
B. Bond base to asphalt layer
C. Prevent rutting
D. Improve drainage
Answer: B ✓
Prime coat promotes adhesion between the granular base and asphalt layer.
7. Asphalt temperature at placement is critical because it affects:
A. Color
B. Compaction and workability
C. Cost
D. Traffic control
Answer: B ✓
Proper temperature ensures adequate compaction and prevents premature
cooling.
8. A slump test is used to measure:
A. Concrete strength
B. Workability
C. Air content
D. Density
Answer: B ✓
Slump indicates consistency and workability of fresh concrete.
