The existing methods for the identification and classification of expansive soils using the common soil classification parameters appear inadequate. This note proposes the use of a modified liquid limit that has already been successfully applied to predict California bearing ratio (CBR). The relationship between this 'equivalent' liquid limit, CBR swell and percentage clay for a series of synthetic soils is examined and the ensuing swell prediction equation shown to give satisfactory results for some natural soil samples.
