| dc.description.abstract | This Master of Science thesis focuses on performance assessment of drainage structures on Alemgena-Butajira road segment. The main target of this research is to indicate a quantity of work that should have been done already, but has not yet been done in keeping the bridge and culverts in their performance to good condition. Bridges and culverts on the road segment that require intervention have been assessed, selected and illustrated in this thesis work. In preparation of this research work, 26 bridges and 169 culverts were registered. Among them 19 bridges and 45 culverts were found defective which need detail inspection for maintenance. The remaining requires only visual regular inspection. The existing status of the structures along the route is presented with support of pictures. Even though Ethiopian Roads Authority has launched regular bridge inspection program that detail inspection in 3 years interval and visual inspection every year for each bridge and culvert structure, the attention given for bridges and culverts maintenance along the route has been very little. A number of the bridges and culverts along the route were found defective and they should be maintained urgently to keep them safe and operational. | en_US |
