Prediction of Swelling Potential for Compacted Clays

Abstract

Study to develop reliable means for predicting potential expansion characteristics of clays from classification test data is described; it is shown that well-defined relationship can be established between percentage of clay sizes present in soil, activity of clay, and percentage of swell under 1-psi surcharge of sample compacted at optimum water content to maximum density in Standard AASHO Compaction Test; charts developed from data.
