| dc.description.abstract | Bridge is one of the most important components of railway line for development of transportation. It is known that Addis Ababa light rail transit project construction started two years ago. Also the construction of national railway project started. In these projects, the construction of bridges need highly skilled man power and highest construction cost. The railway bridge commonly contains two types of tracks which are ballasted and slab track. There is a difference in construction cost of bridge between ballasted track case and slab track case. Thus, this study has attempted to analyze, design and compare both ballasted and slab track type laying on the surface of bridge. This study mainly focuses on the superstructure of bridge supporting track rails attached to the bridge to support trains. The intention of this thesis is therefore to compare the construction cost of railway bridges with ballasted and slab track cases and to select the economical track type laying on the surface of railway bridge. Finally, from the overall analysis result of this thesis, the study conclude that slab track is economical than ballasted track for span length greater than 15m. On the other hand, ballasted track seems economical than slab track for span length less than 15m. | en_US |
