f-d, I have to do a soil stabilization with lime or cement for a pavement subgrade. Clients are more familiar with improved qu (unconfined compressive strength) values however, most of the contractors shown improved CBR values in their catalogs. I just wanted to look at different correlations betweeen qu and CBR to compare with what we have here.

The purpose of this study was to propose a method to quantify the volumetric crack rate (VCR) of red clay and investigate the influence of VCR on the unconfined compressive strength (UCS) of red clay. First, the relationship between wave speed and VCR was quantified by a prefabricated crack method to obtain the equivalent VCR (EVCR).
