Methods of testing soils for engineering purposes, Method 6.1.1: Soil strength and consolidation tests — Determination of the California Bearing Ratio of a soil — Standard laboratory method for a remoulded specimen
This Standard sets out a method for determining the California Bearing Ratio (CBR) of a soil when compacted and tested in the laboratory. The CBR value is measured on the fraction of material passing the 19mm sieve. This Standard is not applicable to materials with more than 20% retained on the 19mm sieve.
