PREDICTION OF SWELLING POTENTIAL FOR NATURAL SOILS

Using test data of 259 naturally occurring soils obtained from 22 counties in Kansas, a well-defined relationship was established between the percentage clay sizes present in a soil, the activity of the soil and the percentage of swell under a 1-psi surcharge of a sample compacted to 92% of standard AASHO density at optimum moisture content. It has been shown that there is an excellent agreement between the predicted swelling and the actual swelling. The average error in predicting the swelling potential for the 26 soils was found to be 6.9%. The prediction equations will serve as a valuable tool in the design of any structure on compacted soils.
