FLYASH STABILIZATION OF TROPICAL HAWAIIAN SOILS

A preliminary study of the soil improvement/stabilization of several tropical Hawaiian soils with locally generated high quality flyash admixtures has shown tremendous potential as an economical method to upgrade these "poor to marginal" types of materials. These preliminary studies have shown such improvements as: increase of unconfined compressive strengths; changes in moisture-density relationships resulting in lower maximum dry densities, higher optimum water content, and less variation of dry density from the maximum over a much wider range of water contents; increases in CBR of more than 10- fold; reduction in plasticity; reduction in swell to less than 10% of the unstabilized values; and greatly increased workability.
