Specifications

The product is used to simulate the effect of traffic and to measure the deformation susceptibility of bituminous sample.

Technical specifications
- The machine fully satisfies both EN 12697-22 and BS 598:110 Specifications.
- 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 x 390 mm and can accept rectangular slabs of several sizes:

305 x 305 mm, 50 or 100 mm high
305 x 400 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
- Matest wheel tracker accepts also samples with dimensions up to 400 x 500 mm, 180 mm high (this mould can be compacted with Matest 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.

Hardware

- Data acquisition and processing system fully managed by microprocessor.
- Multifunctions keyboard with encoder for easy and rapid setup
- Large graphic display 320x240 pixel.
- RS 232 port for connection to PC.

 

Firmware
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.
