The C.B.R. Method is used for finding the relative bearing ration and expansion characteristics of soil of base, sub base and sub grade for the design of roads, pavements and runways.
Test can be made on all types of soils including sand, gravel, crushed stone etc. C.B.R. test is used extensively for selection of materials and control of sub-grades.
The procedure of test is very simple. A 50mm dia penetration piston is forced in the test soil and loads required for the penetration to penetrate different depth are recorded by means of a proving ring fixed to the penetration piston assembly and a dial gauge.
