Asphalt Slab Roller Compactor
- Configuration
- Standard
Slab compactors can compact asphalt slabs to a target density applying specific loads corresponding to those of pavements rollers used in the highway construction.
MeetsASTM D8079 · AASHTO T321 · EN 12697-24 · EN 12697-26 · EN 12697-33
Technical specifications
| Models | 77-PV41A02 |
|---|---|
| Machine control | Vertical displacement of the roller segment by brushless motor measured directly by encoder to verify in real time the specimen thickness Machine fitted with sensors to confirm the mould in position and for the automatic set-up of the horizontal travel |
| Firmware | Set up of compaction procedure with displacement control with load, density or thickness limit. Selection, customization and storing of test parameters. Customization of the compacting procedure to be saved and recalled from the data base. Graphic display of roller vertical displacement vs. number of passes.

- User defined controlled linear speed up to 300 mm/sec and adjustable pause at the mould inversion point
- Ideal for producing test beams for 4-Point bending (EN 12697-24, EN 12697-26, AASHTO T321) and slabs down to 38 mm
- Adjustable heating control system of the sector heads available as option
- Vibrating roller option, adjustable from 10 to 50 Hz
- PRO-COMPACT closed-loop control slab
- Wheel tracking test down to 38 mm thickness
- Cored to provide specimens for indirect tensile, static and dynamic creep tests
- Cut into beams for bending fatigue tests
- Standard models
- Advanced models, which also satisfy the compaction procedure of EN 12697-33 and include other important features.
- The roller segment freely moves by simple friction for better compaction uniformity. A brushless motor (standard models), or stepper motor (advanced models) moves vertically the roller segment under displacement control.
- The vertical load is applied orthogonally to the axis of the travel motion. the mould carriage moves back and forth by linear movement.
- The longitudinal (major) mould dimension correspond to the compaction direction so it is possible to obtain specimens of the proper length conforming to Standards. The lifting machine cover permit an easy access to the mould area. In the “rest” position, the mould is close to the operator for easy positioning while the roller segment is lifted and positioned at the back of the machine.
