The pneumatically powered roller compactor was originally designed to provide a solution to the problem of making homogeneous laboratory specimens large enough to be used for wheel-tracking tests. It is used to compact to either a target mixture density or to provide a standard compactive effort to a range of different asphaltic paving materials. Vibration is available as an option.

The roller compactor can be used for:
Wheel tracking specimens, beams for fatigue and modulus tests, coring into specimens for use in modulus and permanent deformation tests.
