-------------------------------------------------------------------------***--------------------------------------------------------------------ABSTRACT: Infrastructure development plays a crucial role in driving the overall growth of the Indian economy.
However, constructing engineering structures on weak or soft soil poses significant challenges in terms of safety and stability. The foundation of any structure must possess sufficient strength to support the entire load. Among the different types of soil, alluvial soil is commonly used but it exhibits varying behavior with changes in moisture content and has low bearing capacity. Soil stabilization techniques offer effective solutions to enhance the properties of such soil. Additionally, the increasing pace of urbanization and industrialization has led to the generation of large quantities of waste materials, posing environmental challenges in their disposal. Utilizing these waste materials for soil stabilization presents an alternative approach that allows for their high-volume consumption and reduces environmental impact. This paper aims to stabilize alluvial soil using marble dust, burnt brick dust, lime, and burnt brick dust as stabilizing agents. Laboratory investigations encompass determining the Atterberg limits, dry density, California bearing ratio (CBR), and unconfined compressive strength (UCS). The proportions of the stabilizing agents vary from 0% to 40%, with increments of 10% by mass of the dry soil. The results reveal a decreasing trend in the plasticity index as the content of marble dust, lime, and burnt brick dust increases. Furthermore, there is a general increase in the maximum dry density (MDD) and a decrease in the optimum moisture content (OMC) with higher proportions of marble dust, lime, and brick dust. Moderate improvements in CBR and UCS are observed with increasing marble and burnt brick dust content, while significant enhancements are found with higher lime and burnt brick dust content. The stabilization of soil leads to improved subgrade strength, thereby reducing the required thickness of the pavement. These findings demonstrate the potential of utilizing waste materials for soil stabilization, resulting in improved engineering properties, cost-effectiveness, and sustainability in infrastructure construction. By implementing such techniques, the industry can address both environmental concerns and the need for robust foundations in various construction projects.

Alluvial soils typically have low strength, and their engineering properties vary with changes in moisture content. Constructing roads on virgin alluvial soil often requires a thicker pavement and a large quantity of construction materials, resulting in higher costs. Furthermore, the use of quarried aggregates for road construction is prohibited by the government. Therefore, there is a need for innovative approaches to reduce construction costs while ensuring sufficient quality. Soil stabilization is one technique used to improve the quality of subgrade soil and reduce construction costs. However, conventional stabilizing materials such as cement, lime, and chemicals are expensive. Cement stabilization is also less preferable nowadays due to the rising costs and environmental concerns associated with its production. Hence, there is a growing emphasis on promoting the use of non-conventional and waste materials like fly ash, rice husk ash, sugar cane bagasse ash, marble dust, and burnt brick dust for soil stabilization. Several researchers have conducted studies in this field, and a few of their findings are mentioned here. Anitha K. et al. (2009) investigated the effects of marble dust on different types of subgrade soil. They obs erved a significant reduction in the plasticity index as the percentage of marble dust varied, while the optimum moisture content (OMC) decreased and the maximum dry density (MDD) increased with the addition of marble dust. Justo C.E.G and Krishnamurthy (2008) conducted laboratory studies on soils treated with marble powder stabilizer. They observed a reduction of about 35% to 40% in the plasticity index values with the addition of 6% stabilizer, and the soaked CBR (California Bearing Ratio) value of the stabilized soils showed a significant increase, even with a 2% stabilizer content.
