Main Features

  • Completely electromechanically operated
  • Possibility to program user defined procedures as free combination of load and displacement (or combined) controlled cycles
  • Completely electromechanically operated
  • Conforming to EN 12697-33, 5.2 method and ASTM D8079
  • 21” All-in-one touchscreen PC controlled , PC and software included
  • Includes the compaction procedure defined in the brand new EN 12697-33 method 7.3, providing at the beginning a controlled displacement compaction which can grant a flat surface followed by a load compaction phase , which can replicate the real compaction on the road surface
  • Base and foot adjustable heating system available as option
  • 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
  • Vibrating roller option, adjustable from 10 to 50 Hz
  • PRO-COMPACT* closed loop control slabs
  • Customization of compacting cycle which can be saved and recalled from the database
 
*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.

      Models 77-PV41C05
      77-PV41C06
      Machine control - Vertical load and/or displacement control of the roller segment by stepper motor, measured directly by linear transducer to verify in real time the specimen thickness for more accuracy
      - Real time measurement and control with a closed loop logic of compaction load by two precision strain gauge load cells. This system permits to verify possible discrepancies of the compaction due to the wrong distribution of asphalt in the mould  and to any other unexpected malfunctions, with warning to the operator
      - Machine fitted with sensors to confirm the mould in position and for the automatic set-up of the horizontal travel
      Software - 21'' Touchscreen integrated PC
      - Fully programmable PC software operating in Windows®
      - Set up of customized compaction sequence as free combination of load/displacement controlled cycles
      - Selection, customization and storing of test parameters
      - Customization of the compacting sequence to be saved and recalled from the database
