Naturally occurring asphalt is found in geologic strata and can be soft and hard material
Petroleum asphalt is obtained by refining crudes
Cutback asphalt is obtained through liquefying asphalt cement with a solvent (binder)
Grade is based on minimum kinematic viscosity at 60C
, Ductility is a consistency test to measure asphalt cements ability to undergo deformation without breaking
Flash point test is a volatility test to measure the maximum temperature to which an asphalt binder can be heated
without burning
Limestone, sandstone and shale are ________ Sedimentary
aggregates
Basalt and granite are _______ aggregates Igneous
According to the superpave method of mix design, the 4
sieve number for defining the coarse and fine aggregates
is #
Blasting large rock ledges is required for the excavations Crushed
of ______ aggregates/sands
When stockpiling, dropping the aggregates from long Segregation
distances can cause _____
The _____ test is used to grade the low temperature of BBR (Bending Beam Rheometer)
an asphalt binder
If creep stiffness fails and the m-value is still above 0.3, it DTT (Direct Tension Tester)
is recommended to test the low temperature
performance of an asphalt binder using a ____
The High temperature grade of an asphalt binder is DSR (Dynamic Shear Rheometer)
graded using a
The G* divided by sine() factor is representative of Rutting Behavior
the______
The G* multiplied by sine() factore is reoresentact of the Fatigue Performance
_____ of an asphalt binder
The ______ cracking is a pavement distress type that Fatigue Cracking
occurs when the thermal stresses exceed the ability of
asphalt mixture to relive stress through deformation
Aging occurs when asphalt binder reacts with oxygen
Short term aging is due to the volatilization of specific components during the production and
construction of HMA
The superpave software calculates the high temperature for a depth 20 mm below the surface of the mixture
The superpave software calculates the low temperature at the surface of the mixture
