1. Which type of asphalt is typically used for high-traffic roadways?
A. Cold mix
B. Cutback asphalt
C. Hot mix asphalt
D. Surface dressing
Hot mix asphalt provides the durability and load-bearing capacity required
for high-traffic areas.
2. What is the standard slope for proper drainage on paved surfaces?
A. 0.5%
B. 1%
C. 2%
D. 5%
A 2% slope ensures water drains efficiently without ponding.
3. Which equipment is primarily used for compacting asphalt?
A. Backhoe
B. Grader
C. Roller
D. Paver
Rollers apply pressure to compact asphalt layers, ensuring durability and
smoothness.
, 4. What is the main purpose of tack coat in asphalt paving?
A. To waterproof the pavement
B. To mark lanes
C. To bond layers of asphalt
D. To prevent oxidation
Tack coat improves adhesion between existing pavement and new asphalt
layers.
5. Which test measures the stability and flow of asphalt mix?
A. Penetration test
B. Marshall test
C. Slump test
D. Proctor test
The Marshall test evaluates the load-bearing stability and flow
characteristics of asphalt mixes.
6. What is the recommended temperature range for placing hot mix
asphalt?
A. 100–150°F
B. 200–250°F
C. 275–325°F
D. 350–400°F
Hot mix asphalt must be placed within 275–325°F to ensure proper
compaction and bonding.
7. What is the primary function of a prime coat?
A. To color the pavement
B. To prevent rutting
C. To seal and stabilize the base layer
D. To provide traction
A prime coat penetrates the base to improve adhesion with the asphalt
layer.
8. Which type of base material provides the best support for asphalt
pavements?
, A. Sand
B. Gravel
C. Crushed stone
D. Clay
Crushed stone offers superior strength, drainage, and stability for
pavement foundations.
9. What is the purpose of milling in pavement maintenance?
A. To apply sealant
B. To compact asphalt
C. To remove deteriorated asphalt layers
D. To install base layers
Milling removes damaged asphalt to prepare the surface for resurfacing.
10. What does the term “rutting” refer to in asphalt pavements?
A. Cracking
B. Permanent surface depressions
C. Surface wear
D. Stripping of aggregate
Rutting occurs when asphalt deforms under repeated traffic loads.
11. Which type of joint is used to connect two asphalt slabs without
expansion space?
A. Contraction joint
B. Expansion joint
C. Construction joint
D. Isolation joint
Construction joints are used to join pavement layers poured at different
times.
12. How is asphalt pavement thickness typically measured?
A. By weight
B. By volume
C. By depth using a straightedge or gauge
D. By surface color
