WebJan 1, 2024 · Definition. The California bearing ratio (CBR) is an index that compares penetration resistance of laboratory-compacted soil material to that of a durable, well-graded ( poorly sorted ), crushed rock material. WebThe california bearing ratio test is penetration test meant for the evaluation of subgrade strength of roads and pavements. The results obtained by these tests are used with the empirical curves to determine the thickness of pavement and its component layers. This is the most widely used method for the design of flexible pavement.
