Description
EN 12697-46
To carry out
- Direct (uniaxial) tensile tests UTST
- Cooling attempts with hindered linear expansion TSRST
- RT relaxation experiments (with additional device 20-65600)
- Tensile creep test TCT (retardation) with additional device 20-65700
On asphalt test specimens. The system consists of a climate cabinet and a TRAVIS testing machine. This is equipped with a rigid load frame and precision screw jack with stepper motor drive for tensile and compression tests. As an option, a second test frame 20-65300 can also be used in the climatic cabinet and operated with the existing control.
Special adaptation elements above and below enable the tension-free installation of an asphalt test specimen 40 x 40 x 160 mm. Four precision deformation measuring sensors mounted on temperature-indifferent measuring bases are used for deformation measurement. These ensure that their reference lengths do not change under the influence of temperature. Complete with control and regulation electronics as well as Windows operating software TRAVISOFT for controlling the entire test sequence including the climatic cabinet and the testing machine, for ongoing measurement data acquisition as well as for test evaluation. The scope of delivery includes the climate cabinet with observation window in the door and switchable interior light, the input and output unit with touch screen and keyboard, the software and two sets of sample adaptation plates for:
- Direct (uniaxial) tensile test UTST
- Cooling attempt with hindered linear expansion TSRST
- Uniaxial cyclic tensile test UCTST
To glue the sample adaptation plates to the asphalt sample 40 x 40 x 160 mm using a 2-component adhesive, we recommend using the sample mounting device 20-65500.
