Abstract

California Bearing Ratio (CBR) is an important parameter used in design but it is tedious and time-consuming to obtain. This technical note presents and discusses the results of laboratory tests which were performed on plastic soils to identify the soil parameters with a high degree of correlation with CBR. Analysis of the obtained data and the relevant literature resulted in a chart that can be easily used to estimate the CBR of soil based on its plasticity and optimum moisture content.California Bearing Ratio (CBR) is an important parameter used in design but it is tedious and time-consuming to obtain.
