Asphalt/bituminous mixture
Standard asphalt slab roller compactor
Standard electro-mechanical multi-size slab compactors, closed loop control system
EN 12697-33, method 5.2 | ASTM D8079
Main features
- Completely electromechanically operated
- Conforming to EN 12697-33, 5.2 method and ASTM D8079
- 8” touchscreen controlled
- Automatically compacts in displacement controlled mode up to target density/height or up to the (user selectable) load limit
- Mould dimensions: 500 x 400, 500 x 300, 400 x 300, 300 x 300 and 320 x 260 mm, 195 mm height
- Compaction direction in the longest (major) mould dimension to obtain specimens of the proper length conforming to Standard
- Vertical balanced of sliding cover for easy access and complete three side view
- Maximum compaction load 30 kN
- 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
The software is able to combine a load/displacement compaction. This procedure provides at the beginning of the test a controlled displacement compaction, which can grant a flat surface of the compacted slab, followed by a load compaction phase, which can replicate the real compaction on the road surface.
General description
General description
The slab compactors can compact asphalt slabs to a target density applying specific loads corresponding to those of pavements rollers used in the highway construction. The slab can be used for:
The Electromechanical slab compactor can be used as part of your Superpave performance based testing program.
- Wheel tracking test down to 38 mm thickness
- Cored to provide specimens for indirect tensile, static and dynamic creep tests
- Cut into beams for benfing fatigue tests
- Standard models
- Advanced models, which also satisfy the compaction procedure of the brand new EN 12697-33 method 7.3 and include other important features.
The Electromechanical slab compactor can be used as part of your Superpave performance based testing program.
