1. What does the acronym "SP" in Superpave stand for?
a) Standard Pavement
b) Superior Performance
c) Surface Pavement
d) Structural Performance
Superpave was developed as a Superior Performance system to
improve asphalt mix performance under traffic and climatic
conditions.
2. The primary purpose of the Superpave Gyratory Compactor (SGC)
is to:
a) Measure asphalt viscosity
b) Simulate field compaction and determine volumetric
properties
c) Determine binder content
d) Test aggregate shape
The SGC is designed to simulate pavement compaction in the field,
producing samples for volumetric analysis.
3. In Superpave, the design aggregate structure is based on:
a) Aggregate specific gravity only
b) Gradation and nominal maximum aggregate size (NMAS)
c) Asphalt grade only
, d) Temperature susceptibility
Superpave mix design focuses on aggregate gradation and NMAS
to achieve proper density and durability.
4. The term "VMA" in Superpave stands for:
a) Volumetric Maximum Asphalt
b) Voids in Mineral Aggregate
c) Volumetric Mix Analysis
d) Visual Mix Assessment
VMA is the volume of voids between aggregate particles in a
compacted mix, which affects durability and binder content.
5. The target air void content for a Superpave-designed mix is
typically:
a) 2%
b) 3%
c) 4%
d) 6%
Superpave mixes are designed at 4% air voids to balance durability
and resistance to rutting and fatigue.
6. Which of the following is NOT a factor in Superpave binder
selection?
a) Average 7-day high pavement temperature
b) Average 7-day low pavement temperature
c) Aggregate angularity
d) Traffic loading
Aggregate angularity affects mix stability, not binder selection,
which is temperature and traffic-based.
, 7. The "Gyratory angle" in the Superpave Gyratory Compactor is
typically:
a) 0.5°
b) 1.25°
c) 2°
d) 5°
The 1.25° angle simulates field compaction and produces realistic
density profiles.
8. What is the main reason for using the Superpave mix design over
Marshall design?
a) Lower cost
b) Easier testing
c) Better performance under specific climate and traffic
conditions
d) Less material required
Superpave was developed to optimize mixes for climate and traffic,
reducing rutting and fatigue.
9. In Superpave, the "Ndes" refers to:
a) Design aggregate number
b) Design number of gyrations
c) Nominal density estimate
d) Normalized deformation estimate
Ndes is the number of gyrations applied during laboratory
compaction representing expected field traffic.
10. The maximum specific gravity (Gmm) of an asphalt mixture
is used to determine:
a) Asphalt binder grade
