Abstract In this research study, an experimental program was undertaken to investigate the suitability of using mixtures of steel slag and Class-C fly ash and mixtures of steel and blast furnace slags to replace lime in subgrade stabilization applications. Soil-5% steel slag-5% Class-C fly ash, soil-7% steel slag-3% Class-C fly ash, soil-8% steel slag-2% Class-C fly ash and soil-7% steel slag-3% blast furnace slag mixtures were explored as subgrade materials. The clayey subgrade soil collected from the proposed implementation site was characterized prior to stabilization through a series of tests which included, specific gravity, Atterberg limits, grain-size analysis, compaction, CBR-swelling and unconfined compression tests. The mechanical properties of the mixtures of soil, steel slag and Class-C fly ash and of the mixtures of soil, steel slag and blast furnace slag were obtained through compaction and unconfined compression tests. In order to assess the swelling potential of the mixtures of soil, steel slag and Class-C fly ash, CBR swelling tests were also performed on the mixtures.
