- The sample table has Ebatları: 400 x 390 mm and can accept rectangular slabs of several sizes:
- 305 x 305 mm, 50 veya 100 mm high
- 305 x 400 mm, 50 veya 100 mm high
- 200 mm dia. core samples, 50 mm high
The sample confinement Gövdes are not included and have to be ordered separately (see accessories)
- Used in evaluating the deformation depth of a bituminous mixture subjected to cycles of passes of a loaded rubber wheel under constant and controlled temperature conditions. It is used to simulate the effect of traffic and to measure the deformation susceptibility of the bituminous sample.
- It performs the test as per procedures A and B (6 veya 2 tests) as specified by the EN Standart.
- The machine is supplied complete with adaptors for a correct mould positioning and locking.
- The wheel tracker is Donanım 3 temperature probes:
- 1 probe, connected to the thermoregulator, for the control andadjustment of the cabinet temperature.
- 2 probes for temperature measurement inside the specimen.
Technical 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. 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
- Comply with EN 12697-22 and AASHTO T324.
- No lifting of heavy wheel assemblies. Wheels retract automatically away from samples and park into rest position.
- Sturdy machine, designed for the rugged construction laboratory environment stainless steel sample tanks.
- Two independent loaded wheel systems each capable of conducting wet or dry sample tests simultaneously.
- Sliding sample positioning mechanism for easy mould handling and placement in the machine.
- Does not require lifting of heavy wheel components.
- Fully Automatic machine. Detects and stops the test when the target rut depth is reached.
- Touch-screen control unit based on Windows operating system for user friendly execution of the test, management of the data and visualization of the results.
- Each of the two wheel assemblies is equipped with displacement transducers for rut measurement.
- Mechanical recirculating water bath for temperature control within ± 1 °C.
- Easy to load, unload, drain water and clean the unit after each test.
- Small footprint to accomodate small construction labs.
The sample confinement frames are not included and have to be ordered separately (see accessories)
