Abstract - This paper study investigates the feasibility
enhance soil strength, reduce compressibility, and improve durability, making them suitable for subgrade soil stabilization. However, the effective utilization of waste materials as soil stabilizers requires a comprehensive understanding of their properties, behavior, and interactions with soil. This study aims to investigate the use of waste material as a soil stabilizer to enhance the strength of subgrade soil, addressing the knowledge gaps and challenges associated with their application.
and effectiveness of using waste materials as a sustainable alternative for subgrade stabilization in road construction. The study examines the use of two waste materials: Construction and demolition (CD) material and other waste materials. The waste materials were used in the subgrade layer of a road construction project. The results show that the use of CDW and Other waste material improved the subgrade's engineering properties, including increased California Bearing Ratio (CBR) values and reduced settlement. The study also found that the use of waste materials reduced the project's environmental impact by decreasing the amount of virgin materials used and the amount of waste sent to landfills. The findings suggest that waste materials can be a viable and sustainable alternative for subgrade stabilization, offering both engineering and environmental benefits.
2. LITERATURE REVIEW [1] Moataz A. Al- Obaydi, et. al. (2021) evaluated the impact of three different types of CD materials (dragged asphalt, DA; crushed brick, CB; and crushed concrete, CC) The findings revealed CBR values improved after CD materials were added to the CL soil. The inclusion of DA, CB, and CC raised CBR values by 12.4, 13.7, and 49.7% correspondingly. The CBR values increased by 1.1 to 1.7 times, which is equivalent toa 50 to 100 cm increase in layer thickness. Increases in CBR values going forward range from 1.5 to 1.8 times as the layer thickness increases from 50 cm up to 150 cm.
Key Words: Soil subgrade, Construction and demolition materials, Waste Materials, CBR test.
1.INTRODUCTION Subgrade soil is a critical component of road infrastructure, providing the foundation for pavements and ensuring the safety and durability of transportation systems. However, subgrade soils often exhibit poor engineering properties, such as low bearing capacity, high compressibility, and susceptibility to settlement and deformation. These issues can lead to premature pavement failure, increased maintenance costs, and compromised safety. Moreover, the increasing demand for transportation infrastructure development has resulted in a significant amount of waste materials generated from various industries, including construction, mining, and industrial processes. The disposal of these waste materials poses significant environmental and economic challenges, highlighting the need for sustainable and innovative solutions. In recent years, the use of waste materials as soil stabilizers has gained attention as a potential solution to enhance subgrade soil strength, reduce waste disposal costs, and promote sustainable construction practices. Various waste materials, such as construction demolition waste, and waste plastics, have been investigated for their potential to improve soil properties. These materials can

[2] Partab Rai, et.al. (2021) investigated the stabilization of subgrade soils using waste fly ash (FA) and cement (OPC), yielding significant environmental and economic benefits. Laboratory tests (Atterberg limits, free swell index, unconfined compressive strength, California Bearing Ratio, and scanning electron microscopy) were conducted on soil treated with 0-20% FA and 0-8% OPC. Results showed decreased plasticity and swell index, and increased CBR (71.34% improvement) and UCS (48.20% increase) with optimal 20% FA + 8% OPC mixture. This study demonstrates the effectiveness of waste FA and OPC in enhancing subgrade soil stability, offering a costeffective, eco-friendly alternative for pavement and foundation construction, and promoting sustainable waste management. [3] Hemant S. Chore, et. al. (2020) replaced cement with industrial by-products like as fly ash (FA), ground granulated blast furnace slag (GGBFS), silica fume (SF), metakaolin, rice husk ash, etc., provides various advantages.
