About California Bearing Ratio Test Field Type

California Bearing Ratio Test Field Type

To know C.B.R. Values in situ, it is useful in determining the load carrying capacity in the field when in-place density and water contents are such that the degree of sturation is 80 % or greater, when material is conhensionless and coarse grained, such that it is not effected by changes in water contents and when the material has been in-place for considerable time. The loading is effected by means of a mechanical load frames which can be fixed to the under side of a truck.Salient

FAQs of California Bearing Ratio Test Field Type:

Q: How is the California Bearing Ratio Test Field Type operated in the field?

A: This CBR Field Type equipment is manually operated using a hand lever to apply loading up to 50 kN through a mechanical system, allowing for precise control and accurate readings during field testing.

Q: What is the main purpose of using this CBR Field Type apparatus?

A: The primary application is to evaluate the strength of soil subgrades and subbases, which is critical for road and pavement construction projects to ensure proper bearing capacity and longevity of infrastructure.

Q: When should the CBR Field Type test be performed?

A: The test is ideally conducted during site investigations before construction commences, or when assessing soil conditions for ongoing quality control during major earthworks or road-building processes.

Q: Where can this equipment be used?

A: This CBR Field Type apparatus is suitable for both laboratory environments and field sites, making it versatile for a wide range of soil testing scenarios encountered by surveyors, engineers, and contractors.

Q: What are the core components included with this CBR Field Type equipment?

A: The system is equipped with a proving ring, plunger (50 mm diameter), loading yoke, 150 mm surface plate, and a sensitive dial gauge with a least count of 0.01 mm, ensuring complete and reliable testing.

Q: How does the powder-coated rustproof finish benefit the equipment?

A: The powder-coated and rustproof finish increases the equipments durability by protecting against corrosion, making it suitable for extended field use in various climatic conditions.

Q: What advantages does the mechanical advantage provide during operation?

A: The mechanical system with manual operation allows users to exert high loading force efficiently, reducing operator fatigue while maintaining accurate and repeatable penetration rates for reliable CBR values.
