Preliminary studies to determine the effect of mixing fly ash with regional swelling of clayey soils indicated these mixtures were superior in certain engineering properties. Mixtures of clay soil, and fly ash at 10, 20, 30, and 40 percent exhibited reduced plasticity and swelling characteristics while the unconfined compression strength of the mixture increased as the percentage of fly ash increased. Based upon the laboratory test results, the possibility of stabilizing swelling soils by using fly ash in structural fills should be practical. The use of fly ash to reduce high plasticity and swelling in soils may prove to be a useful and inexpensive technique.
