1. Basic Philosophy of asphalt mixture design Economical
Constructable
meet performance expec-
tations
2. What are four present day asphalt products? Asphalt Cements
Asphalt Emulsifiers (wa-
terproofing
Cutback asphalt (water-
proofing)
roof shingles
3. What is the difference between asphalt and tar? asphalt is from petrole-
um/crude oil
tar is from coal
4. Does viscosity increase or decrease as the tempera- Viscosity decreases (in-
ture increases? verse relationship)
5. What effect does the rate of loading have on an as- High Temp + low rate =
phalt pavement? viscous
Low Temp or high rate =
elastic
6. What statistical approach is used in selecting a binder A reliability bell curve is
and what are its benefits? plotted to determine the
reliability of temperature
ranges for a given region
7. What is the effective asphalt content? Effective asphalt content is
the asphalt not absorbed
by the aggregate

8. What tests are used to analyze pavement deformation Rotational Viscometer
potential of an asphalt binder? Dynamic Shear Rheome-
ter
Bending Beam Rheome-
ter
Rolling Thin Film Oven
Pressure Aging Vessel
9. What does the rotational viscometer test help deter- Mixing and compaction
mine? temperature
10. What does the dynamic shear rheometer test help Rutting and pavement de-
determine? formation
11. What does the bending beam rheometer test help Low temperature thermal
determine? cracking
12. What does the rolling thin film oven test determine? Short term aging (dur-
ing mixing, compacting,
placement)
13. What does the pressure aging vessel test determine? long term (10 year) aging
14. What are the different tests to use on an asphalt mix? Rutting (Hamburg wheel
test, French wheel tracking
test, asphalt pavement an-
alyzer)
Fatigure (Bending beam
rheometer)
Thermal cracking
(semi-circular bending
test, disc shaped compact
tension test, DCT, TSRST)

15. What device measures the creep potential of an as- Bending beam rheometer
phalt binder?
16. What are the components of the dynamic modulus? Apply a repeated load at
varying frequencies to a
test specimen over a rela-
tively short period of time
and measure the speci-
men's recoverable strain
and permanent deforma-
tion. Some dynamic mod-
ulus tests are also able
to measure the lag be-
tween the peak applied
stress and the peak resul-
tant strain, which provides
insight into a material's
viscous properties. Test
results correlate reason-
ably well with in-service
pavement rutting mea-
surements but the test
is somewhat involved and
difficult to run.
17. How are air voids determined? Be specific about the Air voids are determined
tests and corresponding properties. using the bulk and max
specific gravities of the
mix, determined by ob-
taining weights of dry, sat-
urated surface dry, and
submerged, and for max,
