  • 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.
  • 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)
