This paper presents the results of laboratory research of fly-ash soil stabilization. Tests were conducted on mixtures with alevrite - very expansive, medium to high plasticity clay and fly ash sampled in thermo electric power plant ”Kolubara”. Effects of fly ash on physical and mechanical properties of soil (grain size distribution, Atterberg limits, moisture-density relationship, unconfined compression strength, effective shear strength parameters, CBR, deformation parameters, swell potential) were evaluated. Results of the research indicate that fly ash can effectively improve some engineering properties of soil. The most significant improvement is the increase in CBR values and reduction of swell potential because it makes this material usable for road construction.
