What is CBR test in soil ?

Question

Accepted Answer

CBR test is a laboratory test used to determine the strength of a soil sample.

CBR stands for California Bearing Ratio.
It is a penetration test that measures the load-bearing capacity of a soil sample.
The test involves compacting the soil sample in a mold and subjecting it to a standard load.
The ratio of the required force to penetrate the soil to the force required for a standard material is calculated.
CBR values range from 0 to 100, with higher values indicating stronger and more compacted soil.
CBR test results are used in the design of pavements, roadways, and other civil engineering projects.

Accepted Answer

The California Bearing Ratio is a measure of the strength of the subgrade of a road or other paved area, and of the materials used in its construction. The ratio is measured using a standardized penetration test first developed by the California Division of Highways for highway engineering.
