Section 1: Highway Construction Fundamentals
1. What is the primary purpose of establishing a highway subgrade?
A. To provide a decorative surface for the roadway
B. To eliminate the need for pavement drainage
C. To provide a stable foundation that supports the pavement structure
D. To increase the thickness of the asphalt surface
Correct Answer: C. To provide a stable foundation that supports the
pavement structure
,Rationale: The subgrade is the prepared soil foundation beneath the
pavement layers. Its strength, stability, moisture condition, and
uniformity directly affect pavement performance. A properly prepared
subgrade distributes traffic loads and helps prevent settlement,
rutting, and pavement cracking.
2. Which document typically establishes the technical requirements for
highway construction materials and workmanship?
A. Contractor's equipment inventory
B. Project specifications
C. Employee attendance sheet
D. Daily weather report
Correct Answer: B. Project specifications
Rationale: Project specifications establish requirements for materials,
construction methods, tolerances, testing, inspection, and acceptance.
Contractors must follow the applicable contract specifications,
approved plans, and governing standards. Equipment records and
daily reports support project administration but do not normally
define the technical acceptance criteria.
3. What is the primary purpose of a highway cross section?
,A. To show the contractor's payroll information
B. To establish the project's insurance requirements
C. To identify the manufacturer's equipment warranties
D. To show the roadway's transverse profile, including pavement,
shoulders, slopes, and drainage features
Correct Answer: D. To show the roadway's transverse profile,
including pavement, shoulders, slopes, and drainage features
Rationale: A cross section illustrates the roadway as viewed
perpendicular to its centerline. It identifies features such as pavement
width, crown, shoulder configuration, side slopes, ditches, and
existing or proposed ground elevations. Contractors use cross sections
to calculate earthwork quantities and guide construction.
4. What is the purpose of a roadway crown?
A. To direct surface water toward the roadway edges
B. To increase the roadway's vertical clearance
C. To eliminate the need for storm drains
D. To prevent all pavement deformation
Correct Answer: A. To direct surface water toward the roadway edges
, Rationale: A crown is the transverse slope that allows water to drain
from the roadway surface toward the shoulders, gutters, or other
drainage facilities. Proper cross slope reduces standing water and
helps limit water infiltration into pavement layers. The required crown
depends on the road design and applicable specifications.
5. What does the term "right-of-way" mean in highway construction?
A. The area reserved exclusively for construction equipment storage
B. The right of a contractor to change project specifications
C. The legally established area acquired or designated for roadway
purposes
D. The portion of pavement open only to emergency vehicles
Correct Answer: C. The legally established area acquired or designated
for roadway purposes
Rationale: The highway right-of-way is the property or legal corridor
designated for highway use and associated facilities. It may contain
the roadway, shoulders, drainage systems, slopes, utilities, and other
improvements. Contractors must verify property limits and avoid
unauthorized work or storage outside permitted areas.
