CBR–Marshall Machine 50 kN, 3-Speed, Digital

The 50 kN CBR–Marshall Digital Machine is a computerized loading frame designed to perform both CBR and Marshall tests with high accuracy and repeatability. Equipped with three fixed and selectable speed ranges, the system allows full compliance with major international standards and supports a wide range of bituminous and soil testing applications.

Speed selection is performed through an integrated electric switch, enabling the operator to quickly choose among:

• 1.00 mm/min – CBR (Australian and old BS Standards)
• 1.27 mm/min – CBR
• 50.8 mm/min – Marshall

The loading frame shares the same mechanical structure as model S213-05N, ensuring robust construction, stable operation under load, and long-term durability in high-usage laboratories.

This digital configuration is supplied with the Cyber-Plus Progress data acquisition system (B044M-SET), a load cell, and a displacement transducer, enabling real-time monitoring, automated test execution, and efficient data processing. Accessories for specific test setups must be ordered separately.
