Function |
| Dynamic
Shea Rheometer (DSR) |
Measures
rheological properties, complex shear modulus
- (stiffness
or resistance) & phase angle of asphalt cements.
|
| Bending
Beam Rheometer (BBR) |
Tests
the deflection of a beam of asphalt from the stiffness modulus
& log slope of the creep curve. |
| Rolling
Thin Film Oven (RTFO) |
Tests
short term aging to simulate construction aging of asphalt binders. |
| Direct
Tension Tester (DTT) |
Determines
failure strain of asphalt binders in direct tension at a single
rate of elongation. |
| Pressure
Aging Vessel (PAV) |
Simulates
in-service aging of asphalt binders. |
| Rotational
Viscometer |
Outlines
determination of high temperature viscosity of asphalt
- binders
(unaged).
|
| Gyratory
Compactor |
Makes
asphalt sample for SuperpaveTUpavement
analysis. |
