Roller compactor

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.

• Slabs can be from 50 to 100mm thick.

• Slabs can be 305x305mm or 305x405mm

• Vibrating roller

• Safety cage with three side complete vision

• Easy to maintain

• Adopt Japanese Mit-subishi PLC automation control system, safe, reliable and stable; it has perfect selfprotection

function, capable of long operation under complicated driving conditions.

• Use Japan Mit-subishi touching screen to realize manmachine interaction with clear and visible Chinese- English interface, operate steadily by easy touch and display real-time data.

• Japanese Pana-sonic transducer can arbitrarily change vibration frequency between 0-50Hz.

• Fanlike steel roller.

• Maximum compaction load is 55Kn, equivalent to maximum static site rolling compaction.

• One-step molding of test specimen according to preset height or density.

• PLC allows to set times of rolling compaction under each load in sequence of P1, P2, P3 and P4; P1 can be set to minimum times of 2, then add load through P2, P3, and P4.

• Compaction load can be adjusted and set by 4 pressure-regulating valves.

• Vibratory compaction, adjustable frequency, simulated site vibration rolling compaction.

• 3 safe protection doors; opening any of them can break air, cut electricity to protect operator and prevent

wrong operation.

• Test specimens can be used to wheel tracking test, and can be used to indirect tensile test after coring, or

to be cut for fatigue test.

• Molds easy to insert and remove.
