Product code IT-SL750
CBR test machine 50 kN
Electromechanical 50 kN machine for determining the California Bearing Ratio (CBR) of soils and base courses.
- 24-month warranty and spare parts from stock
- Commissioning, staff training and methodological support
- Assistance with equipment certification as part of your laboratory
Description
The machine is designed for determining the CBR value — the resistance of soil and road base materials to penetration by a standard plunger. The value is used in pavement design and in quality control of the subgrade.
The electromechanical drive maintains the standard penetration rate of 1.27 mm/min; the load cell and displacement transducer feed data to the controller, which automatically records the loads at penetrations of 2.54 and 5.08 mm and calculates the CBR in percent.
The scope of supply includes a ⌀ 49.6 mm penetration plunger, CBR moulds with surcharge weights and a swell measurement tripod with an indicator. With interchangeable fixtures the machine can also be used for Marshall testing.
