Abstract - An Expansive soil (ES) is soil that has the ability
states, expansive soils can cover large areas, sometimes encompassing entire districts or regions. For example, the Indo-Gangetic plain, which spans across several states in northern India, is known for its expansive soils [3]. Stone dust is created when larger stones are crushed into smaller pieces. The dust is produced during the crushing process, as the stones are broken down into smaller and smaller pieces [4]. Stone dust is often mixed with other materials, such as sand or cement, to create a stable base for a variety of construction projects. The use of stone dust for stabilizing expansive soil for pavement construction has been studied in several research studies. Stone dust has been found to be an effective stabilizer for expansive soils due to its ability to improve soil properties such as compaction, shear strength, and permeability. One study evaluated the use of stone dust for stabilizing expansive soil in pavement construction in India [5]. The study found that the addition of stone dust to the expansive soil improved its California Bearing Ratio (CBR), which is a measure of the soil's strength and loadbearing capacity. The study also found that stone dust reduced the soil's plasticity index and improved its permeability. Another study conducted in Nigeria evaluated the use of stone dust for stabilizing expansive soil in pavement construction. The study found that stone dust improved the soil's CBR and reduced its swell potential [6]. The study also found that the addition of stone dust improved the soil's workability and reduced its susceptibility to erosion. Overall, the use of stone dust for stabilizing expansive soil for pavement construction has shown promising results in various studies. However, it is important to note that the effectiveness of stone dust as a stabilizer may depend on factors such as the type and amount of stone dust used, the soil properties, and the environmental conditions. Therefore, it is recommended to conduct site-specific testing and evaluation to determine the most appropriate stabilizer and application rates for a particular project.
to swell or shrink significantly due to changes in moisture content. It is also known as swelling soil, shrink-swell soil, or clay soil. Expansive soils are typically composed of clay minerals that have the ability to absorb water and expand, and then release water and shrink. This study used stone dust (SD) for the improvement of engineering properties. Stone dust, also known as crusher dust or quarry dust, is a type of fine material that is made by crushing stones and rocks. It is often used as a subbase material for paving projects such as roads, driveways, and construction projects. Different tests to evaluate the Liquid and Plastic limit, free swell index (FSI), compaction, unconfined compressive strength (UCS), and California bearing ratio (CBR) are used to characterize the effects of adding stone dust in expansive soil. According to the test results, stone dust with a percentage of 0, 10, 20, 30 and 40% improves the engineering characteristics of expansive soil so that it may be utilized for constructing pavement.

1. INTRODUCTION Expansive soil is soil that swells and shrinks significantly as the moisture content in it changes. It is also known as swelling soil. Expansive soils are typically composed of clay minerals that have the ability to absorb and hold water molecules [1]. When these clay minerals absorb water, they expand and push against anything that is above them, including foundations, roads, and sidewalks. The swelling and shrinking of expansive soils can cause damage to structures built on them, such as cracks in walls and foundations, uneven floors, and other structural problems. This is because the soil's movement can cause the foundations of buildings to shift, which can lead to structural damage. Expansive soils are found in many parts of the world, but they are particularly common in arid and semiarid regions where there is a large fluctuation in soil moisture levels between wet and dry seasons. To mitigate the effects of expansive soils, engineers and architects use specialized foundation designs and building techniques that can accommodate the soil's movement, such as using flexible materials and creating a moisture barrier around the foundation. Expansive soils are particularly prevalent in the states of Uttar Pradesh, Rajasthan, Haryana, Punjab, Maharashtra, Gujarat, and Andhra Pradesh [2]. In these
