Question 1
What is the primary purpose of conducting a subgrade soil inspection before
paving operations begin?
A. To determine the surface drainage patterns
B. To assess compaction and stability of the supporting layer
C. To measure the temperature of the asphalt mix
D. To check the alignment of pavement striping
Answer: B. Proper inspection ensures the subgrade is stable and compacted to
support pavement loads and prevent future failures .
Question 2
The maximum allowable deviation in cross slope for a newly constructed asphalt
pavement should generally not exceed what percentage from the design
specifications?
A. 0.5 percent
B. 1 percent
C. 2 percent
D. 3 percent
,Answer: C. Cross slope ensures proper drainage, and most specifications allow
up to a 2 percent deviation from the design .
Question 3
When inspecting concrete pavements, what is the minimum recommended curing
period before opening the pavement to traffic?
A. 1 day
B. 3 days
C. 7 days
D. 28 days
Answer: C. Proper curing strengthens the concrete, and opening to traffic before
7 days can damage pavement integrity .
Question 4
During asphalt placement, what is the primary indicator that adequate
compaction has been achieved?
A. Temperature readings of the mat
B. Density testing results
C. Visual uniformity of the surface
D. Surface smoothness measurements
Answer: B. Density testing confirms the pavement has been compacted to
specifications, ensuring long-term performance .
Question 5
Which methods are commonly used to determine the in-place density of
compacted subgrade soil?
A. Nuclear gauge only
B. Sand cone test only
,C. Proctor test only
D. Nuclear gauge and sand cone test
Answer: D. Both nuclear gauge and sand cone tests are standard methods for
verifying field compaction .
Question 6
The primary reason for performing a proof roll on a prepared subgrade is to:
A. Check for settlement and weak areas
B. Verify soil moisture content
C. Measure surface smoothness
D. Determine the soil temperature
Answer: A. A proof roll identifies soft or unstable areas that may settle under
traffic loads .
Question 7
A nuclear density gauge must be calibrated in accordance with the manufacturer's
recommendations and which other requirement?
A. State regulations
B. Project specifications
C. Federal guidelines
D. Daily weather conditions
Answer: B. Calibration ensures the gauge readings are accurate for determining
in-place density according to project specifications .
Question 8
Excessive segregation in asphalt mixtures can lead to which pavement distress?
A. Improved surface friction
B. Premature rutting or cracking
, C. Increased compaction
D. Enhanced drainage
Answer: B. Segregation results in non-uniform mixtures, reducing durability and
causing premature failures .
Question 9
When inspecting a new highway embankment, which factor is most critical to
prevent future settlement?
A. Slope aesthetics
B. Compaction and moisture control
C. Aggregate color
D. Traffic sign placement
Answer: B. Proper compaction and moisture control prevent settlement and
ensure long-term stability .
Question 10
Which test measures the resistance of an asphalt mixture to deformation under
traffic loads?
A. Marshall stability test
B. Slump test
C. Proctor test
D. CBR test
Answer: A. The Marshall stability test evaluates the load-bearing capacity and
resistance to deformation of asphalt mixtures .
Question 11
What is the primary cause of rutting in asphalt pavements?
A. Insufficient curing time
B. Weak subgrade or mix design issues
