Abstract: In the present paper, expansive soil samples with different swelling potentials are studied for their microstructure features, and the causes for the expansion are studied from the analysis of soil structure. Based on these studies, a microstructure classification method has been proposed for evaluation of different swelling potentials which may serve as a means to evaluate the swelling potentials of the soil in engineering practice.
