Attempts have been made by various researchers to suggest methods for identification and classification of expansive soils. This paper is concerned with the comparison of the predicted equations of swelling potential of expansive soils. A comparison between nine different predicted equations for swell percent was carried out. The results brought from each equation are later compared to experimental results for soil samples obtained from three different site locations chosen according to their swelling potential: moderate, high and very high. A conclusion for the use of the predicted equations based on these comparisons is outlined in this work.
