ARC – Asphalt Roller Compactor, Electromechanical system

High load, hot roll, multi size

STANDARD: EN 12697-33

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 page 98).

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:

Sturdy frame made of steel

– Mould supporting table with alternating displacement system, for

table displacement and vertical load pressure

Integrated touch screen control unit based on Windows operating

system. The control unit runs like a standard PC for the

management and analysis of data, test results, graphs.

The touch-screen icon interface allows an easy set up of the

parameters and an immediate execution of the test.

Direct Internet and Intranet (LAN) connection for remote

technical assistance. This features allows operators to establish

a remote communication and receive software updates or an

immediate diagnostic analysis of the potential problem from

Matest technicians. Hardware technical details: see pag. 24

Unlimited memory storage with: 2 USB ports,1 SD card slot.

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

DETAIL OF THE CONTROL PANEL

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 (see accessories).

Power supply: 230V 50/60Hz 1ph 2100W (3100W with the heated

segment roller)

Dimensions: 2200×1030 xh 1880 mm (2410mm with opened guard)
