Availability:

TBTBBR-1 Bending Beam Rheometer is designed according to AASHTO T313, ASTM D6648 and EN 14771 to perform flexural creep stiffness of asphalt binder at the low-temperature condition.

Each TBTBBR-1 consists of load frame, built-in touch screen industrial computer, fluid bath, chiller, calibration kit, air compressor and power box.


1. Industrial computer display curve of deformation, pressure and temperature in real time;

2. LVDT sensor meet standard measurement requirement;

3. Dual mode of Peltier and chiller for fast cooling from room temperature to -18℃ in 40 minutes;

4. Fluid bath temperature fluctuation within ±0.1℃ at set temperature;

5. Smoothly switch contact load(35±10mN) and test load(980±10/50mN);

6. The chiller connect to the main main host by long hose to prevent vibration;

7. Adjustable speed magnetic stirring rotor make the fluid bath temperature accurate and uniform;

8. Thin beam modulus in range of 20GPA±10% that meet standard required Daily Overall System Check;

9. Durable stainless steel frame has good corrosion resistance and easy to clean;

10. Time point for calculating result can be set by software;

11. Automatic calculate test result and generate report;

12. Two-stage high-precision air filter prevents air impurities from affecting the test accuracy;

13. USB port support data export and connect with mouse & keyboard;

14. With Ethernet port, can connect to Internet;

15. English and Russian language operation software, other language can be customized.
