PAVELAB SYSTEMS Standard electro-mechanical multi-size slab compactors, closed loop control system

  • Download:
EN 12697-33, method 5.2 | ASTM D8079
Main features
  • Completely electro-mechanical operated
  • 8'' touchscren controlled
  • Automatic compaction by displacement controlled compaction procedure in closed loop control
  • High slab quality by the innovative PRO-COMPACT* system
  • 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 height, to be filled at 155 mm max
  • Compaction direction in the longest (major) mould dimension to obtain specimens of the proper length conforming to Standard
  • Vertical sliding cover for easy access and complete three side view
  • Maximum compacting load 30 kN
  • Automatically compacts to target density/height or load limit
  • 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
  • Compaction sector heating system and roller vibration (with adjustable frequency) options
  • Moulds easy to install and to remove
  • Safety systems conforming to CE standards
*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.
General description
General description
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:
- Wheel tracking tests down to 38mm thickness.
- Cored to provide specimens for indirect tensile, static and dynamic creep tests.
- Cut into beams for bending fatigue tests.
 
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. 
 
Firmware
- Set up of compaction procedure with displacement control with load, density or thickness limit.
- Selection, customization and storing of test parameters
- Customization of the compacting procedure to be saved and recalled from the data base
- Graphic display of roller vertical displacement and load vs. number of passes
- Possibility to pre-set a load threshold to start compaction at the contact of the sector head with the specimen
 
Machine control
- Vertical displacement of the roller segment by brushless motor, measured directly by encoder to verify in real time the specimen thickness to eliminate the errors due to the deformation of the machine structure
- The longitudinal (major) mould dimensions correspond to the compaction direction, to obtain specimens of the proper length conforming to standards.
-The machine is fitted with sensors to confirm the mould in position and for the automatic setup of the horizontal travel.
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.

Upgrading options (to be specified at the time of order)
  • Control heating system for sector heads of the roller segment fitted with heating system
  • Optional roller segment vibrator, to simulate the on-site vibratory rollers. Adjustable frequency from 10 to 50 Hz.
An alternative model is available, suitable for low-thickness slab, featuring molds height 155 mm high (to be filled at 120 mm max) and very affordable price (see model 77-PV40A02 / 77-PV40A04)
