ADVANCED ELECTROMECHANICAL SYSTEM, HIGH LOAD, HOT ROLL, MULTI SIZE
STANDARD: EN 12697-33 method 5.2 and EN 12697-33 annex A | ASTM D8079
Asphalt Roller Compactor is entirely developed and manufactured by Matest. The machine works with an electromechanical 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 (see p. 112) and Matest
Smartracker B038A (see p. 114). 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.
Possibility to use standard or heated segment rollers of different
sizes (see accessories): width up to 400 mm, length up to
500 mm and radius 490 mm, to obtain slabs of
500×400 mm, thick up to 180 mm
400x305x25 to 100 mm thick
320 x260 mm, thick up to 180 mm
305x305x25 to 100 mm thick
Vertical force selectable up to max. 40 kN (for all machine)
Programmable density target compaction
Policarbonate safety guard as requested by CE Directive
Possibility to perform the two-phase procedure (Pre-compaction
and Compaction) as specified by TP Asphalt-StB 33 and
EN 12697-33 annex A
The required n° of passes can be set before starting the test
allowing an accurate test control by n° of passes
Sliding carriage speed adjustable between 3 m/min and 12 m/min
Detailed output file listing each pass and displaying duration,
sample height, applied load and eventual roller and cart temperature
Power supply: 230 V 50-60 Hz 1ph 2100 W
(3100W with the heated segment roller)
Dimensions: 2200x1030x1880 mm
(2410 mm with opened guard)
Weight: 1300 kg approx.
Three transducers are installed to manage the roller and table displacements and vertical load pressure.
The compaction cycle can be programmed up to a certain load or deformation value. When deformation value is programmed, the
system automatically programs the suitable loads to obtain the selected final thickness.
The flexibility of the program grants the production of samples with uniform density and dimensions, fully meeting Standards Spec.
and Research requirements.
A friendly and easy to use interface allows an immediate and fully automatic test execution, data acquisition and processing, test report and file.
The Roller Compactor is supplied without roller segment, slab mould, centering plate, that must be ordered separately

HEATING OF SEGMENT ROLLER AND SLIDING CART
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 of:
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,
to be connected to the control unit B039-02.
