B039N ARC-Asphalt Roller Compactor

( Asphalt )

  • EN 12697-33
  • TP Asphalt-StB
  • 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 with 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.
The sample slabs can be also cored or cut off to obtain cylinders and beams for run tests, bending fatigue, indirect tensile, static and dynamic creep, stiffness and 4-point tests.

Heating of the Segment Roller

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

Control Unit

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

Sliding Cart Heating Option

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