California Bearing Ratio Test Apparatus, Field Type Manufacturer,Supplier and Exporter in India
Product Code : JA-ST-9788
The California Bearing Ratio Test Apparatus, Field Type (SKU JA-ST-9788) measures the CBR of soil in place, using piston penetration to find the load-carrying capacity of sub-grades and bases for roads and runway pavements. The loading assembly is mounted on a rolled steel joist cantilevered from the back of a truck, or fitted to the underside of a mobile frame, which provides the reaction for the test.
Specifications
The apparatus data cover the test method, the mounting and the site conditions it suits.

Applications of the field CBR test apparatus
The field test gives the bearing ratio of the material as it lies on site, which is useful for:
- Checking sub-grade strength along road alignments
- Evaluating bases on runway and airfield pavement works
- Site control on large road construction projects
- Field practicals in highway and transportation engineering courses
Scope of supply and ordering
The listing covers the field CBR apparatus; say whether it will be fitted to a truck-mounted joist or to a mobile frame.
Frequently asked questions
How is the field CBR apparatus mounted?
It is mounted on a rolled steel joist cantilevered from the back of a truck, or fitted to the underside of a mobile frame, which carries the reaction for the penetration piston.
On which soils does the field CBR test give useful results?
It is most useful where the in-place density and water content give a degree of saturation of 80% or more, and where coarse-grained, cohesionless material is not significantly affected by changes after placement.
What does the test measure?
It measures the California Bearing Ratio by piston penetration, giving the load-carrying capacity of sub-grades and bases for roads and runway pavements.
