The HDM-4 tool provides the deterministic approach in data input and processing also utilizes data on existing road condition, traffic volume and crust composition to predict road deterioration as per the road conditions in terms of any one variable such as cracks, roughness, pothole, raveling, etc. Highway Development and Management device, HDM-4 programming, created by the World Bank for worldwide applications is used for recognizing an ideal upkeep technique for roadway pavements. Pavements which are left to weaken without promising support treatment are probably going to require major rehabilitation and reconstruction much sooner than those which are legally kept up. HDM-4 simulates the use of best alternatives based on the Economic Internal Rate of Return (EIRR) and Economic Net Present Value (ENPV) values The HDM-4 tool collects the data related to existing road condition, traffic volume, axle surveys etc. This project briefly describes the use of HDM-4 for project analysis of National Highway NH-234 of length 56.53km.

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. 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. Later it is analyzed using the IITPAVE Software to check whether it satisfies the specific requirements. 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.

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.

The failure of bitumen pavement is due to fatigue cracking and rutting deformation. Roads are used by different vehicle class which results in failure of the pavement due to early deterioration. Road transport plays a vital role in social, economic and industrial development of the country.
