The TBTMWD-2 Marshall stability tester digital display is applicable to the testing of asphalt mixture stability in order to accurately judge the breaking point of the asphalt mixture, assist in calculation of the design ratio in the asphalt mixture, and pavement quality inspection. It features high-precision loading & displacement transducers, instrument automatic print load-deformation curve and test results.

The TBT-0709A Marshall stability tester is designed in strict accordance with T0709-2011 standards, and is designed to carry out Marshall stability testing for bituminous materials.

• This instrument allows users to set parameters, calibrate instruments, carry out automatic test control, automatic data collection and set a timer. The control unit will collect stability and flow value samples to automatically judge the peak value.
• The LCD touch screen displays the stability, flow value, curves, result and time. Test effects are also intuitive.
• 100 groups of test data and test times are easily stored and retrieved as needed. All procedures are automatically controlled.
• The RS232 communication port ensures communication with the upper computer. The data process, store, print and display is PC controlled, as are all test procedures.
