B039 ARC-Asphalt Roller Compactor

( Asphalt )

  • EN 12697-33
  • ASTM D8079

This Roller Compactor entirely developed and manufactured by Matest, fully operates with the electro-mechanical system, and therefore  it does not require any air source (compressor) or hydraulic pressure.
It is used to produce representative sample slabs of several dimensions of bituminous mixtures laid and compacted on site.
The compaction is performed through a segmented roller with alternated operated rotation which simulates the on-site action of a street roller. The compaction cycle can be programmed in accordance to a certain load or deformation value.
The flexibility of the program grants the production of samples with uniform density and dimensions, fully meeting Standards specifications and research requirements; these samples are compatible for rut test with Matest Wheel Tracking apparatus B038.
The sample slabs can be also cored or cut off to obtain cylinders and beams for bending fatigue, indirect tensile, static and dynamic creep, stiffness, and 4-point tests.

MAIN FEATURES:

  • 40 kN vertical force.
  • Sturdy frame made of steel.
  • Alternating displacement system, for table displacement and vertical load pressure.
  • Integrated touch screen control unit based on Windows operating system.
  • Easy management and analysis of data, test results, graphs.
  • Touch-screen icon for an easy parameters set up and an immediate test execution.
  • Unlimited memory storage with: 2 USB ports,1 SD card slot.
  • Direct Internet and Intranet (LAN) connection for remote technical assistance and for software updates.
  • Heating of the segment roller (optional).
  • Simple and quick roller and mould positioning.
  • Perfect horizontal flatness of the slab surface.
  • Uniform density and dimensions of the slabs.
  • Easy to maintain.
  • Energy controlled compaction procedure.
  • Silent compaction

Heating of the Segment Roller

Possibility to heat and control temperature of the Segment Roller mounted on the Compactor and Sliding Carriage to keep the mould warm and avoid thermal shocks the might affect specimen’s workability.
The equipment is composed by:

B039-02
Control Unit

Mounted in the Roller Compactor, it foresees a thermoregulator circuit, complete with probe to measure and to adjust the temperature from room up to 180°C. It is connected to the segment roller equipped with heating resistances.

B039-03
Sliding Cart Heating Option

Thermoregulated circuit with temperature probe to set and control cart temperature and keep mould hot.
