CBR Test Apparatus – Digital
The test can be performed in the laboratory on prepared samples or in-situ on location. Because of the empirical nature of the test, it is valid only for the application for which it was developed i.e., the design of highway base thickness.
This load frame is designed for conducting Unconfined, Triaxial, CBR and other routine tests.
The loading system comprises of a screw jack with detachable handle. The lower platen moves up and down. The top bracket is adjustable for vertical clearance and has an adaptor for connecting standard load cells. A display sensor mounting bracket is provided on one of the two pillars and a data acquisition system accompanies the equipment. Rate of strain: 1.00 and 1.27 mm/min.
