• 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.
