Correlation between cbr and spt

WebThe analysis of test results have shown that a non-linear relationship exists between CBR and Mini SPT value of a Subgrade Soil. The relationship was statistically more sound when CBR and mini SPT as determined at same level were correlated in comparison of that between CBR at 25cm and Mini SFr value at 50cm depth. This is attributed to the ... WebCorrelations between CBR and DCP naturally depend on the DCP used. Several correlations have been suggested between DCP results and CBR, especially for pavement design, as given in Table 3.11. ... One of the practical uses of the SPT in fine-grained soils is to use N to make an estimate of the undrained shear strength. In soft to very soft ...
