ABSTRACT This study aims to develop an empirical equation to predict the California Bearing Ratio (CBR) based on the results of the TVA Penetrometer (Hand Cone Penetrometer) test on soft soils, particularly in coastal areas. Soil samples were prepared by mixing bentonite clay, kaolin, and sand, then compacted and tested in the laboratory to obtain CBR values and QcTVA readings. Stepwise re…
