Testing Principle of TT- CBR50 Automatic CBR Tester

Switch on the power to start the instrument. Verify that the system is functioning normally by checking whether the loading mechanism can move smoothly up and down. Once all operating conditions are confirmed to be normal, you may proceed with preparing and starting the test.

Test Standards of TT- CBR50 Automatic CBR Tester

ASTM D1883, JTG 3430‑2020, GB/T 11132‑2002, EN 13286-47

Application of TT- CBR50 Automatic CBR Tester

It is widely used for evaluating the bearing capacity and deformation characteristics of soils and pavement materials in highway engineering, railway construction, airport pavement assessment, and geotechnical research. It is suitable for testing compacted soil samples and base materials to determine their load‑carrying ratio, providing essential data for foundation design, pavement structure analysis, and material quality control. The instrument is particularly valuable in laboratories and engineering units that require precise, repeatable, and automated CBR testing for construction and geotechnical projects.

Features of TT- CBR50 Automatic CBR Tester

• Equipped with overload protection and drop over‑position protection to ensure safe operation.
• Easy to operate, providing accurate test data with stable and reliable performance.
• Automatic testing and data storage, allowing the instrument to complete the test and save results without manual intervention.
• Industrial touch‑screen interface for direct, clear display of test data and convenient operation.
• Simple startup procedure: switch on the power, verify normal operation (beam rising and falling), and begin testing once all functions are confirmed.
