law.resource.orgCalifornia Bearing Ratio ( CBR >. This method was used by the Cali- fornia State Highway Department in USA until 1950 for evaluating subgrade strengths for design of flexible pavements. The ratio is used in conjunction with curves evolved through a study of the performance of the flexible pavements.
