This software product was developed by TxDOT for the use of TxDOT engineers and consultants and is maintained by the Texas Department of Transportation. For a complete listing of the changes made to BGS Version 8.1 to yield BGS Version 9.1, see the Release Notes for BGS Version 9.1 installed with the software. Such limitation existed since long before the release of RDS Version 8.0. 8.1) released June 2007.īGS, Version 9.1 includes a large number of fixes to bugs reported since the release of BGS Version 8.1 as well as enhancements to address user's concerns, including reducing system limitations on numbers such as the number of diaphragm lines that could be defined. BGS v8.1.7.2 was deployed in November of 2011 as a technical release to address OS issues with v8.1.7 (i.e. The result of these changes to RDS is BGS, a "scaled down" implementation of TxDOT RDS that focuses on bridge geometrics. in the bridge plans as needed to accurately fabricate and place the various bridge elements during construction as well as determine bid item quantities during preparation of the PS&E package.īGS Version 8.1, the initial release of BGS (June 2007), was developed from TxDOT Roadway Design System (RDS) Version 8.0 by removing all non-bridge related RDS commands. Included in the text output are geometric data and reports that may be imported into various MicroStation design files to include angles, dimensions, elevations, etc. Optimum alternative is selected based on alternative which yields maximum Net Present Value /Cost Ration and high Economic Internal Rate of Return (EIIR).The TxDOT Bridge Geometry System (BGS) is useful for bridge geometric design. HDM-4 is used for the present project analysis by using the existing data of upgraded six lane road in order to select the best economic alternative from four different maintenance alternative strategies. HDM-4 simulates the best alternative that need to be applied based on Economic Internal Rate of Return (EIRR) which consist Total Transportation Cost (TTC), Vehicle Operating Cost (VOC), roughness pattern for various alternatives which are evaluated using HDM-4. 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.
