Description
EN 12697-24, EN 12697-25, EN 12697-26
Dynamic Test System 50 kN / 60 Hz for asphalt and bituminous mixtures for use with a large climatic chamber / high stiffness test frame 20-61000, 20-61100, 20-60200 or 20-61300 for the determination of the resistance against fatigue, permanent deformation and stiffness of pavement materials.
Contains:
⦁ High rigid and stiffness test frame with four columns and mounted servo hydraulic actuator 50/60 kN (dynamic/static load) with internal measurement of the displacement and high accuracy load cell for use in climatic chambers
⦁ Water-cooled hydraulic aggregate with high performance servo-hydraulic valve (on request optional available also air cooled)
⦁ Digital controller with 4 channels (standard configuration), TFT-Monitor and PC
⦁ Including closed loop Controlling- and Data-acquisition System BASDA Windows® based with real-time graphic and test data base for load or displacement controlled tests
⦁ Automatic control of the climatic chamber and dynamic BASDA
⦁ Free programmable test procedures or standardized test procedures according EN, ASTM, AASHTO or TP Asphalt StB in use with different test frames, for example 20-62500.
Additional test frames or sample adapters have to be ordered separately. An optional use of a second load cell 5 kN or 10 kN is also possible.
