practical application necessary for lawful, safe, and ethical practice.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of subgrade preparation before highway construction?
A. Reduce asphalt production costs
B. Provide a stable foundation for the pavement structure
,C. Increase traffic lane width
D. Improve pavement color consistency
🟢 B. Provide a stable foundation for the pavement structure
🔴 Explanation: Subgrade preparation ensures the underlying soil can adequately support the
pavement structure and traffic loads. Proper preparation minimizes settlement, rutting, and premature
pavement failure.
Question 2
Under Louisiana contractor licensing law, a license is generally required when a project's value
exceeds:
A. $10,000
B. $25,000
C. $50,000
D. $100,000
🟢 C. $50,000
🔴 Explanation: Louisiana requires contractor licensing for projects exceeding $50,000, except where
specific classifications have lower thresholds, such as electrical, mechanical, and plumbing work.
Question 3
A contractor discovers that a supplier has been providing materials that do not meet project
specifications. The supplier offers a substantial personal rebate if the contractor continues ordering.
What is the MOST ethical response?
A. Accept the rebate because it does not change the invoice price
B. Accept the rebate if the supplier replaces defective materials
C. Keep the rebate confidential and continue using the supplier
D. Reject the improper benefit and address supplier performance through proper channels
🟢 D. Reject the improper benefit and address supplier performance through proper channels
🔴 Explanation: A personal rebate tied to purchasing decisions creates an undisclosed conflict of
interest. Supplier performance must be evaluated on quality, compliance, and contractual obligations,
not personal financial incentives.
Question 4
,According to Louisiana DOTD specifications, the contractor must notify the Engineer a minimum of
how many hours before beginning construction operations?
A. 12 hours
B. 24 hours
C. 48 hours
D. 72 hours
🟢 B. 24 hours
🔴 Explanation: A 24-hour notification allows the Engineer to schedule personnel, arrange testing
equipment, and conduct required pre-activity inspections before work begins.
Question 5
What is the primary function of aggregate base beneath asphalt pavement?
A. Provide decorative appearance
B. Distribute loads and improve drainage
C. Prevent pavement striping
D. Reduce traffic speed
🟢 B. Distribute loads and improve drainage
🔴 Explanation: Aggregate base supports pavement loads while allowing water to drain away from the
pavement structure, protecting against moisture damage.
Question 6
Which soil type generally provides the highest bearing capacity for roadway construction?
A. Organic soil
B. Peat
C. Well-graded gravel
D. Expansive clay
🟢 C. Well-graded gravel
🔴 Explanation: Well-graded gravel provides superior load-bearing capacity and drainage
characteristics compared to organic soils, peat, or expansive clays.
Question 7
, What does "cross slope" primarily accomplish on a roadway?
A. Improve visibility
B. Increase lane width
C. Promote drainage from the pavement surface
D. Reduce concrete strength
🟢 C. Promote drainage from the pavement surface
🔴 Explanation: Cross slope allows water to drain from the roadway, reducing hydroplaning risk and
preventing pavement deterioration from standing water.
Question 8
The "Permanent or Paved Highways and Streets (Asphalt)" classification is what type of designation?
A. A major classification
B. A subclassification of Highway, Street, and Bridge Construction
C. A specialty for concrete work only
D. A classification for federal projects only
🟢 B. A subclassification of Highway, Street, and Bridge Construction
🔴 Explanation: Asphalt paving is a subclassification within the broader Highway, Street, and Bridge
Construction major classification, focusing specifically on asphalt road work.
Question 9
Which document specifies project construction requirements, materials, and workmanship standards?
A. Equipment log
B. Payroll report
C. Project specifications
D. Employee handbook
🟢 C. Project specifications
🔴 Explanation: Specifications define materials, testing requirements, construction standards, and
workmanship expectations for the project.
Question 10
What is the purpose of a prime coat in pavement construction?
