1. What type of work is primarily covered under the Tennessee HRA-A
classification?
A. Structural steel erection
B. Grading and drainage
C. Railroad signal installation only
D. Building demolition
Rationale: HRA-A is the Grading and Drainage classification. Its scope
includes grading, drainage pipe and structures, and clearing and
grubbing. Proper grading and drainage are fundamental to
constructing stable transportation facilities.
2. Which activity is specifically associated with HRA-B.1?
A. Bridge painting
B. Railroad construction
,C. Base construction
D. Pavement marking
Rationale: HRA-B is Base and Paving, and HRA-B.1 specifically
addresses base construction. The base layer provides structural
support beneath the pavement surface.
3. HRA-B.2 covers which type of pavement work?
A. Concrete bridge repair
B. Hot and cold mix asphalt
C. Pavement marking
D. Railroad track construction
Rationale: HRA-B.2 is the asphalt category covering hot and cold mix
asphalt. Proper material selection, placement, compaction, and
temperature control are important to asphalt pavement performance.
4. Which HRA-B subcategory addresses concrete paving?
A. HRA-B.1
B. HRA-B.2
C. HRA-B.3
D. HRA-B.4
,Rationale: HRA-B.4 is Concrete Paving. This category addresses paving
work using concrete rather than asphalt or surface-treatment
materials.
5. What is the primary purpose of a pavement base course?
A. Provide decorative color
B. Eliminate the need for drainage
C. Provide structural support beneath the pavement
D. Replace traffic control devices
Rationale: The base course distributes traffic loads and provides a
stable foundation for the pavement surface. Its strength, thickness,
drainage characteristics, and compaction can significantly affect
pavement life.
6. Why is proper subgrade preparation important before placing
pavement?
A. It eliminates all pavement maintenance.
B. It makes traffic control unnecessary.
C. It provides a stable foundation for the pavement structure.
D. It prevents all water from entering the project.
, Rationale: The subgrade supports the pavement system. Weak,
improperly compacted, or poorly drained subgrade can lead to
settlement, rutting, cracking, and other pavement failures.
7. What is the principal purpose of compaction during earthwork?
A. Increase soil moisture indefinitely
B. Increase soil density and improve stability
C. Remove all aggregate from the soil
D. Eliminate the need for testing
Rationale: Compaction reduces air voids and generally increases soil
density, strength, and stability. Proper moisture content and
appropriate equipment are important for achieving the specified
density.
8. Which HRA classification specifically addresses bridges and
culverts?
A. HRA-A
B. HRA-B
C. HRA-C
D. HRA-E
