The Field CBR Set is used for in-situ evaluation of the California Bearing Ratio (CBR), a critical parameter for assessing the mechanical strength of road subgrades and base layers.
Utilizing a mechanical jack with a two-speed gearbox, the apparatus applies controlled loads to a penetration piston, enabling accurate measurement of soil resistance under field conditions.
A high-precision load ring with a capacity of 50 kN ensures reliable force measurement, while dual dial indicators capture penetration depth with fine resolution, facilitating precise data collection.
The inclusion of extension rods and surcharge weights allows for testing at various depths and simulates overburden pressures, enhancing the versatility of the testing procedure.
Designed for portability and ease of assembly, the Field CBR Set is ideal for on-site testing, providing immediate insights into soil bearing capacity without the need for laboratory facilities.
The device can be easily converted into a laboratory testing setup by installing it into a CBR conversion frame, making it a versatile solution for both field and lab applications.
