Multi Speed CBR Marshall Test Machine for CBR and Marshall Testing

The Multi Speed CBR Marshall Test Machine is designed to perform both CBR (California Bearing Ratio) and Marshall tests using a single 50 kN test frame. Combining two testing methods in one machine helps laboratories reduce equipment costs while maximizing workspace and operational efficiency.

The adjustable upper crosshead allows quick replacement of the testing accessories required for either CBR or Marshall testing. Equipped with a high-precision Sematron LCD digital controller and a servo-driven electromechanical system, the machine delivers accurate, repeatable, and fully controlled testing performance.

The machine operates at 1.27 mm/min for CBR testing and 50.8 mm/min for Marshall testing, fully complying with relevant BS and ASTM standards. Test results are displayed on the digital controller, stored automatically, and can be transferred to a computer for further analysis and reporting.
