Investigation of the correlation between California bearing ratio and shear strength of pavement subgrade material with different water contents

Abstract

Highlights• CBR and shear strength of subgrade soil were found experimentally • The effect of the water content on CBR and shear strength of subgrade soil • A new correlation is proposed between CBR and shear strength values • Prediction of CBR using the Hand Vane Shear test and existing correlations • Comparison between experimental results and existing correlations
