RAVIS Testing system for rheological behaviour of asphalt

Testing system for tests according to EN 12697-46

- uniaxial tension stress test (UTST)
- thermal stress restrained specimen test (TSRST)
- relaxation test (RT)
- tensile creep test (TCT)

This testing system includes a compact test frame completely integrated in the test space of the temperature chamber.
Disturbing feedthroughs are not necessary. As measurement base two bars consisting of a special temperature indifferent material are used. These bars are aligned close to the sample.
The specimen can be user-friendly inserted, the measuring sensors are disconnectable. The rigid test frame is completely made of stainless steel. The specimen load is applied via heavy-duty screw jack and stepping motor. An electronic load cell is directly attached to the spindle. The data logging of the load cell, the four displacement transducers, the temperature sensors for the sample and the test space are monitored with a high- precision data acquisition system. The included PC is used for measurement data logging, control of the test procedure and the temperature test chamber.
The scope of delivery includes a test and evaluation software that can individually be adapted to the users requirements.
The inside of the temperature chamber is made of stainless steel, the front door is equipped with an inspection window.
Two sizes of test chambers are available.
