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 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.

This slab roller compactor PROCOMP can compact asphalt slabs to a target density applying specific loads corresponding to those of pavements rollers used in the highway construction.
The slabs produced can be used for:
The machine can compact 500 x 400 mm, 500 x 300 mm, 400 x 300 mm, 300 x 300 mm and 320 x 260 mm moulds, 195 mm high, to be filled at 155 mm max. (interchangeable) by completing it with the suitable accessories. Maximum slab thickness varies with bitumen mixes composition.
All versions feature a solid high stiffness steel frame, with ergonomic design and safety devices conforming to CE standards.
Featuring a compacting system by roller segment head radius 535 mm. The roller segment freely moves by simple friction for better compaction uniformity. A brushless motor 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 closed to the operator while the roller segment is lifted and positioned at the back of the machine.
MOULD DIMENSIONS: 500 x 400 mm, 500 x 300 mm, 400 x 300 mm, 300 x 300 mm and
320 x 260 mm, 195 mm high, to be filled at 155 mm max.
The longitudinal (major) mould dimensions correspond to the compaction direction, to obtain specimens of the proper length conforming to standards.
