WebThe in-situ California bearing ratio (CBR) test is typically used for road, runways or car park pavement design to assess the strength of the sub-grade. The test involves driving a cylindrical plunger of a defined area into the soil at a uniform rate. This requires the use of a reaction load, (for example, a four wheel drive vehicle or ... WebThe California bearing ratio (CBR) test is a penetration test used to evaluate the potential strength of subgrade, subbase, and base course material including recycled materials. The results are used for the design of roads and airfield pavements. The test was first developed by the California State Highway Department.
