Abstract

This paper detailed an investigation in which archival data for some selected Natal soils were used to evaluate the existing mathematical and graphical prediction models for the California bearing ratio (CBR). It descriptionbed how the relationships between CBR and various classification parameters (in both simple and multivariate forms) were further examined when these existing models were found to be generally unsatisfactory, and then discussed the lack of any suitable correlations in the data capable of providing a universally applicable prediction model. The good relationship between CBR and maximum swell was examined, further research into the influence of the clay fraction on CBR prediction was reported and the interim use of the shrinkage and grading moduli to obtain minimum CBR values for shrinking and non-shrinking soils respectively was proposed.
