DETERMINATION OF DISPERSIVE CLAY SOIL ERODIBILITY BY USING A PHYSICAL TEST

This paper introduces a new, physical, test method for identification of dispersive clay soil behavior. The significance of this form of internal erosion and the need for such a test are discussed. An analysis of dispersive clay soil behavior is included as a base for understanding the physical erosion test. The theoretical background, apparatus, and process of the proposed physical erosion test are presented. Data for average percentage of erosion were determined during 142 tests on 18 samples of varied properties. Physical erosion test results are correlated with those determined by a chemical property method and the method of plotting soil chemical data on a graph that has empirically derived zones of dispersive clay soil behavior. Correlations achieved are significant. We concluded that dispersive clay soil behavior depends on the particular combination of chemical, physical, and mineralogical properties of the soil. The physical erosion test and the erosion device used are shown to provide the measure of dispersive clay soil erodibility needed by soils engineers to predict accurate field behavior.
