The California Bearing Ratio (CBR) is a measure used to evaluate the strength of subgrade soil and its ability to support loads, often utilized in road design. This test compares the bearing capacity of a soil sample with that of a standard crushed stone material, which helps determine the thickness of pavement required for roads. A higher CBR value indicates better soil …

its performance tests like compaction, strength have been performed to suit as a fill and sub-grade material in place of sand and natural soil. Parameters like density, angle of shearing resistance, CBR, drainage, etc., were performed. From the test results it was identified that crusher dust achieved higher densities and maintained
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 ...
The strength characteristics of compacted crusher dust and Crushed Stone mixes have been evaluated through a series of CBR tests by varying the crusher dust and sand contents from 60% to 10%. In addition to that the suitability of compacted crusher dust as a road base and sub-base materials have been verified in accordance with MORTH ...

In addition to that the suitability of compacted crusher dust as a road base and sub-base materials have been verified in accordance with MORTH ...
CBR is short for California bearing ratio. This test measures how much a given material—such as soil or asphalt—resists penetration. This resistance is the bearing capacity. Engineers compare the material's bearing …
From the test results it is identified that plasticity characteristics were decreased and CBR values were increased with addition of Crusher Dust. Form the test results it is also identified that 10-15% of Crusher Dust is required for these gravel soil to make them low-plastic and 10-25% is required to make them non-plastic and high values of CBR
