The improvement of a country's infrastructure is essential to its economic, social, and industrial growth. These connect people and goods throughout communities and regions, serving as the backbone of our economy and society. These help a variety of industries, from agriculture to manufacturing to tourism, grow by attracting new consumers, suppliers, and staff. This paper's goal is to examine how well and for how long a flexible pavement holds up under different loads and climates. This project entails gathering field data for traffic studies, determining the CBR of the subgrade soil, and creating a flexible pavement in accordance with the requirements of IRC: 37-2012. IITPAVE software is used to analyze the structural behavior of the pavement and predict its performance over time. The article describes the research techniques and conclusions that were utilized to evaluate the initiative. From the findings, it is clear that IITPAVE software can accurately predict pavement behavior and provide insight on the structural response to different loads and environmental circumstances. The study concludes with software-based recommendations for enhanced pavement design and upkeep. This study delves further into how IITPAVE software may be used to examine flexible pavement, and is easiness for the future of sustainable road design.
