Slab compactors can compact asphalt slabs to a target density applying specific loads corresponding to those of pavements rollers used in the highway construction.

Slabs can be used for: 

  • 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

The slab compactors come in two versions:

  • 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.

Electromechanical slab compactors feature a compacting system by roller segment head radius 535 mm.

How it works

  • 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 while the mold carriage moves back and forth by linear movement.
  • The longitudinal (major) mold dimension correspond to the compaction direction so it is possible to obtain specimens of proper length conforming to Standards.
  • The lifting machine cover permit an easy access to the mould area. In the “rest” position, the mold is close to the operator for easy positioning while the roller segment is lifted and positioned at the back of the machine.

The Electromechanical slab compactor can be used as part of your Superpave performance based testing program.

*PRO-COMPACT closed-loop is an innovative mechanical and electronic control that combines orthogonality of the load, pendulum motion of the head and sinusoidal non-friction forward-reverse carriage movement. This results in an optimally compacted sample that features Planarity Regularity and hOmogeneity (PRO). The combined load/displacement compaction 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.
