ADVANCED ELECTROMECHANICAL SYSTEM, HIGH LOAD, HOT ROLL, MULTI SIZE
Asphalt Roller Compactor is entirely developed and manufactured by Matest. The machine works with an electromechanical system, andtherefore 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 specificationsand research requirements; these samples are compatible for rut test with Matest Wheel Tracking apparatus B038 and MatestSmartracker B038A . The sample slabs can be also cored or cut off to obtain cylinders and beams for bending fatigue, indirecttensile, static and dynamic creep, stiffness, and 4-point tests.

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, thesystem 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 be ordered separately.
