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

 
*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 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.
