California bearing ratio test equipment.

California bearing ratio is the percentage of stress a soil specimen can resist for a certain amount of penetration relative to the value of stress of which a standard soil could resist. The florida limerock bearing ratio lbr fm 5 515 laboratory test was developed to evaluate limerock and other soils used for the base subgrade and embankment materials typically found in florida. California bearing ratio cbr test machines the california bearing ratio cbr test is a measure of the strength of subgrade soil and highway sub base and subgrade via a penetration test. It is designed for testing cohesive materials with a particle size less than 19mm in australia the governing standard is as 1289 6 1.

It is with the standard circular piston at the rate of 1 25mm min. Cbr is the ratio of the force required per unit area that is needed to penetrate the soil mass. Full crb test required apparatus full test procedure the calculation to evaluate california bearing ratio and uses of the test result is explained here. Penetration piston for cbr test is required for california bearing ratio cbr testing of soil and base.

The results of these tests are used with the curves to determine the thickness of pavement and its component layers. This cbr testing set provides accurate results for the california bearing ratio test due to technical difficulties checking out with a credit card may fail.

The laboratory c b r. The california bearing ratio test cbr test is a penetration test developed by california state highway department u s a for evaluating the bearing capacity of subgrade soil for design. The california bearing ratio test usually called cbr test is an empirical test developed in california usa for determining the relative bearing ratio and expansion characteristics under known surcharge weight of base sub base and sub grade soils for the design of roads pavements and runways. Apparatus consists of a mold of 15 cm internal diameter with a base plate and collar.

It is the ratio of force per unit area required to penetrate a soil mass with standard circular piston at the rate of 1 25 mm min.
