This project highlights the significance of roads in promoting sustainability, economic growth, and social development by improving connectivity. It focuses on the use of AutoCAD Civil 3D software to enhance the efficiency and accuracy of highway geometric design, including horizontal and vertical alignments and cross-sections. Civil 3D simplifies modelling using survey and topographic data from sources like LIDAR and GIS, allowing for quick adjustments and compliance with IRC standards. The software also helps generate corridors, sample lines, and material reports. Additionally, the project involves traffic data collection and CBR testing and for different CBR values to design a flexible pavement using IITPAVE software &IRC-37:2018, ensuring the pavement meets stress and strain criteria at various layers.
