    Abstract

    The dynamic cone penetrometer (DCP) test is being increasingly used for assessing the California bearing ratio (CBR) values of sub-grade soil in the field. The purpose of this laboratory investigation was to establish a correlation between CBR and DCP for soils stabilized with Class C fly ash. In this laboratory study, natural soil (Type CL-lean clay) mixed with Class C fly ash was used to establish the correlation at different percentages of Class C fly ash and moisture. It was found that a good correlation exists between CBR and DCP for Class C fly ash-stabilized soils and that the correlations are similar to those developed by other researchers. The correlations developed here may be used for rapid field determination of CBR values of clay soils stabilized with Class C fly ash.
