California bearing ratio test (CBR) is defined as the ratio force per unit area which is required to penetrate a mass of soil with the standard … See more It is conducted for evaluating the stability of soil sub grade and other flexible pavement materials for the design of pavement thickness. See more Briefly, the penetration test consists of causing a cylindrical plunger of 50 millimeters diameter to penetrate a pavement component material at 1.25 mm per minute. The load values to cause 2.5 millimeters and 5 … See more 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 resilient modulus. WebCALIFORNIA BEARING RATIO TEST 1.Objective CBR is the ratio expressed in percentage of force per unit area required to penetrate a soil mass with a standard circular plunger of 50 mm diameter at the rate of 1.25 mm/min to that required for corresponding penetration in a standard material. The ratio is usually determined for penetration of 2.5 ... minecraft ftb one server
