The rise of worldwide population and industrial technology has boosted raw material demand and solid waste generation. Disposal and storage of industrial wastes are difficult. This study examines how red gypsum (RG) and blast furnace slag (BFS) can be used in road construction. Red gypsum, a titanium dioxide byproduct, and blast furnace slag, a steel manufacturing byproduct, were tested for improving lateritic soil geotechnical qualities. The study focuses on the waste utilization benefits of using lateritic soil mixed with different percentages of RG and BFS. Experiments are conducted to analyze the impact on soil parameters, including maximum dry density (MDD), optimum moisture content (OMC), unconfined compressive strength (UCS), and soaked california bearing ratio (CBR). The combined effect of both BFS and RG on laterite soil is explored, with particular attention to the previously unstudied soil-BFS-RG mixture. The results indicate that the optimal mix proportions vary for the soil-BFS and soil-RG mixtures, with 15% BFS deemed ideal for maximum dry density and 10% BFS for optimal unconfined compressive strength. Similarly, for the soil-RG mixture, 5% RG yields the highest dry density, while 15% RG results in the maximum unconfined compressive strength. The soil-BFS-RG mixture exhibits promising results, with 15% BFS and 5% RG identified as the optimal combination for compaction and 10% BFS and 15% RG for unconfined compressive strength. The study concludes that the proposed mixtures can significantly enhance the properties of lateritic soil, providing a sustainable solution for soil stabilization and construction applications. Further, the soil-BFS-RG mixture, despite requiring additional thickness for pavement, proves to be an economical and feasible option for long-term performance improvement.
