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.
Heating of the Segment Roller
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.
Sliding Cart Heating Option
Thermoregulated circuit with temperature probe to set and control cart temperature and keep mould hot.
