used for fatigue, stiffens and dynamic endurance tests for mastic and hot rolled asphalt and other stiff materials in a climate chamber with exchangeable test frames. The servo-hydraulic power unit is equipped with a digital controller and high resolution load measuring system as well as an incremental displacement measuring system. The complete test is controlled with PC and Windows software including data acquisition, evaluation software of test results and data base function. Special test and evaluation software with variable top and bottom load and time, different types of curves etc. can be created by the user.

LOW TEMPERATURE ASPHALT TESTING
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
