1. Which of the following is the primary purpose of quality control in
asphalt pavement production?
A. To meet contractor profit targets
B. To ensure the mix meets specified requirements
C. To reduce the use of virgin materials
D. To increase compaction speed
Quality control in asphalt production is focused on ensuring that the
produced mix meets the technical specifications required for
durability and performance.
2. What is the optimum asphalt binder content in a mix design primarily
intended to ensure?
A. Lowest possible air voids
B. Maximum stiffness
C. Adequate coating and void filling without excessive binder
D. Maximum aggregate size
The optimum asphalt binder content balances adequate coating of
, aggregates and filling voids without producing excessive binder that
could lead to rutting.
3. In asphalt mix quality control, “FTS” stands for:
A. Fast Thermal Sample
B. Field Test Station
C. First Toe Sample
D. Fine Aggregate Angularity
FTS refers to the first toe sample collected from the production line
for initial quality tests.
4. The maximum theoretical specific gravity (Gmm) of an asphalt mix is
used to calculate:
A. Asphalt binder viscosity
B. Workability
C. Percent air voids
D. Compaction temperature
Gmm is used with field or laboratory bulk specific gravity to
determine the percent of air voids in the compacted mix.
5. A common test to determine the aggregate gradation is:
A. Sieve analysis
B. Marshall stability
C. Penetration test
D. Boil test
Sieve analysis measures the particle size distribution of aggregates to
verify compliance with specification gradation limits.
6. Which parameter reflects the resistance to permanent deformation in
an asphalt mixture?
A. Tensile strength
B. Volumetric shrinkage
C. Rutting resistance
, D. Thermal cracking potential
Rutting resistance measures the mix’s ability to resist permanent
deformation under load.
7. The purpose of the Superpave gyratory compactor is to:
A. Measure binder ductility
B. Simulate field compaction for design
C. Determine asphalt density in-place
D. Test moisture susceptibility
The Superpave gyratory compactor simulates field compaction
conditions to produce specimens for design and performance testing.
8. A mix that shows high air voids in lab compacted specimens likely
indicates:
A. Excessive binder
B. Poor aggregate packing
C. Too much fine aggregate
D. High moisture content
High air voids usually indicate inadequate aggregate interlock and
packing in the mix.
9. The Asphalt Content Test (Extraction) determines:
A. Aggregate moisture only
B. Percent asphalt binder in a mix
C. Binder viscosity grade
D. Asphalt adhesion characteristics
The extraction test measures the proportion of asphalt binder
present in a hot mix asphalt sample.
10. Percent voids in mineral aggregate (VMA) is important because
it affects:
A. Aggregate color
B. Asphalt adhesion
