Abstract:

The present study deals with prophecy of plate load test response from theory of elasticity solution as well as California Bearing Ratio (CBR) test. The response of elastic half space in CBR mould model in FEM was generated and the relationship between modulus of elasticity (E) and CBR was derived. In addition, the correlation between E and CBR was proposed and using E values, coefficient of subgrade reaction (ks) predictions were discussed. Thus, CBR test is expected to simplify the effort in determination of ks which is used in pavement design.
