California bearing ratio

The California Bearing Ratio CBR 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 Empirical tests measure the strength of the material and are not a true representation of the
