Abstract: Road transport plays a vital role in social, economic and industrial development of the country.Roads are used by different vehicle class which results in failure of the pavement due to early deterioration.The failure of bitumen pavement is due to fatigue cracking and rutting deformation.This paved a way for developing the software like IITPAVE which determines the stress and strains values at critical location at different layer of pavement.This project aims at collection of data related to traffic studies and subgrade soil CBR values from the field and designing the flexible pavement as per the guidelines of IRC: 37-2012.Later it is analyzed using the IITPAVE Software to check whether it satisfies the specific requirements.An international studies have been carried out by World Bank to extend the scope of HDM-3 Model and to provide an organized system approach to the road management with adaptable and user-friendly software tools.This has resulted in development of new set of Highway Development and Management tools referred as HDM-4 Software by incorporating various new features to work all around the world with any environmental and engineering situations.This project briefly describes the use of HDM-4 for project analysis of National Highway NH-234 of length 56.53km.The HDM-4 tool collects the data related to existing road condition, traffic volume, axle surveys etc. to predict the road deterioration.HDM-4 simulates the use of best alternatives based on the Economic Internal Rate of Return (EIRR) and Economic Net Present Value (ENPV) values Keywords: fatigue, rutting, IITPAVE, world bank, HDM-4 software.
