WHEEL TRACKING APPARATUS, MATEST PRODUCTION
This test, developed in laboratory, consists in evaluating the deformation (rut) depth of a bituminous mixture subjected to cycles of passes of a loaded rubber wheel under constant and controlled temperature conditions.
To perform the test, a wheel tracking apparatus is used to simulate the effect of traffic and to measure the deformation susceptibility of the bituminous sample.
Matest wheel tracker performs the test as per procedures A and B (6 or 2 tests), clearly specified by the EN Standard.

ROLLER COMPACTOR
This Roller Compactor entirely developed and manufactured by Matest, fully operates with the electro-mechanical system, and therefore “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 in the roads.
The compaction is performed through a segmented roller with alternated operated rotation simulating the on-site action of a street roller.
Slabs are compacted up to the selected density and are then compatible for rut tests with B038 Matest Wheel Tracker.
The slabs can also be cored or cut off to obtain cylinders and beams for bending fatigue, indirect tensile, static and dynamic creep, stiffness, 4-point tests, etc.
TECHNICAL SPECIFICATIONS:
- Possibility to use standard or heated roller segments of different sizes (see accessories): width up to 400mm, length up to 500mm and radius 490mm, with obtainable slabs dimensions of:
320x260mm thick up to 180mm
305x305x25 to 100 mm thick
400x305x25 to 100 mm thick
500x400mm, thick up to 180mm

MATEST GYRATORY COMPACTOR
Matest Gyratory Compactor is used to simulate and reproduce the real compaction conditions under actual road paving operations, hence determining the compaction properties of the asphalt.
Such compaction is achieved by combining the rotary action and the vertical resultant force applied by a mechanical head.
The Compactor comprises a highly rigid steel frame ensuring excellent angle control.
Load is applied by an electro-pneumatic cylinder, servo-controlled by a precision pressure regulator; the height is measured by a linear transducer.
Gyratory motion is generated by an eccentric high precision system allowing an easy set up with precision and constant angle of gyration.
The rotation speed is controlled by an inverter through on board computer control.
Using the proper perforated mould, the Compactor is able to run tests also on cold emulsified asphalt mix.
The acquired results are also employed in the investigation of volumetric and mechanical characteristics of the asphalt mix.
MAIN FEATURES:
- Highly rigid steel frame ensuring excellent angle control.
- Electro-pneumatic action with servo-controlled regulator.
- Electronic control unit with touch screen color display, that runs like a standard PC based on Windows operating system.
The touch-screen icon interface allows an easy set up of the parameters and immediate automatic execution of the test, data acquisition, processing, graphics and file.
Direct connection to Intranet (connection to a LAN network) and Internet to establish a remote communication and receive an immediate diagnostic analysis of the potential problem from Matest technicians, or for software updates.
Unlimited memory storage with: 2 USB ports, 1 SD card.
