The California Bearing Ratio (CBR) test, is used to estimate the load bearing capacity and mechanical strength of highway subbases and subgrades. Originally developed by the California Department of Transportation, it is now widely used in the design of roads, pavements, car parks
Crusher Run, on the other hand, can be graded to various sizes but most commonly is offered in 75mm – dust or 40mm – dust. There is no specification for crusher run and therefore it differs from Type 1 in both particle size and frost susceptibility. Where the crusher run is produced in a quarry that also produces a fully graded Clause 803 ...
The California Bearing Ratio test, commonly abbreviated to CBR, is normally used an empirical measure of road sub-grade strength. This strength value is then often used as either a guide to the design of road layer thicknesses, or to assess compliance of sub-grade against minimum specification values. The test therefore is of use to both ...

Normally the CBR value of 2.5 mm penetration which is higher than that at 5 mm penetration is repeated as CBR value of material; But, if the CBR value at 5 mm is greater than at 2.5 mm penetration, repeat the test. If again test gives similar result then the higher value at 5 mm is reported as a CBR value of the material. Correction
Crusher Run is a blended mix of coarse aggregates and fine aggregates. These aggregates are comprised of crushed stone and stone dust (fine particles that are left over from the larger stone crushing process) which produces a very low void content and is crucial for a strong compaction factor.
Crusher run is typically used underneath concrete slabs, patios, driveways, sidewalks, and walkways and ranges in sizes from ½" to 4″ with stone dust. The size of the crusher run will depend on how much weight the area will need to support and how much drainage is required. Typically, a 4-inch layer of crusher run will provide enough ...

The C.B.R. value usually is selected at 2.5 mm penetration. If the C.B.R. at 5 mm is greater than at 2.5 mm, the test should be repeated. If the check test results are similar, then the value for 5 mm penetration is used as. Generally, the CBR test is conducted for three test specimens and the average value is taken of the three.

The California Bearing Ratio (CBR) test is fully described in BS1377: Part 9: 1990: Soils for civil engineering purposes. It was first developed by the California State Highway Department and is used in the field as an arbitrary strength test which is considered to stress soils and replicate wheel loads.
termed a 'crusher-run'. If it is unable to achieve the required grading directly and continuously from crushing, screen the material into at least four fractions and reconstitute the material to conform to the Specifications by mixing it together in a pug mill. Material finer than 425 micron shall have Plasticity Index (PI) not exceeding 6.
