STANDARDS: EN 12697-22 | BS 598:110 | Comparable to NF P98-251-1, P98-251-4
This machine is used in laboratory, for 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 fully satisfies both EN 12697-22 and BS 598:110 specifications and may perform the test following both procedures A
and B, clearly specified by the EN Standard.

Accepts mould up to 500×400 mm,
180 mm high.
Perfectly fit for slabs made by Matest
ARC Asphalt Roller Compactor.
Continuous realtime rut depth
Three temperature probes for
temperature control and adjustement.
Automatic control of machine and test.
Realtime display of: number of cycles,
rut depth, temperatures.
Realtime cycle rate also displayed when
using a serial connection to PC.

Travel of the table: 230 ± 5 mm
Table cycle frequency: adjustable 15 to 40 cycles per minute.
Hard rubber tyred wheel having outside diameter 200 mm
Wheel load on the sample:
700N ±10N (EN 12697-22) or 520N (BS 598:110)
The load is applied on the sample through a lever.
The effective load applied on the sample can be adjusted by
micrometrical weights positioning.
Continuous real time rut depth measurement (penetration of the
wheel into the sample) through a linear transducer 40 mm travel
by 0.01 mm accuracy.
The test frame is made of robust aluminium alloy and it is contained
in a climatic cabinet with adjustable temperature from
30 to 65 °C ± 1.0 °C
The cabinet is equipped with two doors with insulated glass
for inspection
The sample table has dimensions: 400×390 mm and can accept
rectangular slabs of several sizes:
305×305 mm, 50 or 100 mm high
400×305 mm, 50 or 100 mm high
200 mm dia. core samples, 50 mm high
The sample confinement frames are not included and have to be
ordered separately (see accessories)
Matest wheel tracker accepts also samples with dimensions up to
500×400 mm, 180 mm high (this mould can be compacted with
Matest ARC: Asphalt Roller Compactor)
The machine is supplied complete with adaptors for a correct
mould positioning and locking
The wheel tracker is equipped with 3 temperature probes:
1 probe, connected to the thermoregulator, for the control and
adjustment of the cabinet temperature.
2 probes for temperature measurement inside the specimen.

Data acquisition and processing system fully managed by microprocessor.
Multifunctions keyboard with encoder for easy and rapid setup
Large graphic display 320×240 pixel.
RS 232 port for connection to PC.
The multilingual testing firmware allows:
Management and automatic control of machine and test.
Setup of all test parameters.
Test data acquisition and processing
Real time display of: number of cycles, rut depth, temperatures.
Real time cycle rate will also be displayed when using a serial
connection to PC
Calibration menu for setting and checking all test data.
From the control board, it is possible to select parameters, set
data acquisition and processing according to EN and BS test
procedures, with:
Identification data of the sample (slab) under test.
Cycle frequency.
Number of passes to end the test.
Max rut depth to end the test.
Sampling frequency of the rut depth.
Testing temperature.
Sample (slab) thickness.
