Abstract:
Now a day, the road network in Ethiopia provides the dominant mode of freight and passenger
transport and thus plays a vital role in the economy of the country. Accordingly, the Ethiopian
government allocated sufficient budget to maintenance-heavy economical roads. One of the
heavy maintenance road projects that carried out by ERA with this fiscal year is Butajira Wereba-Hossana-Areka-Sodo (BWHAS) B51, road-heavy maintenance Projects. The objectives
were addressed by detail review of literature about the subject matter and also by collecting
relevant data which used for Butajira-Wereba-Hossana-Areka-Sodo (BWHAS) 195km which
required an appropriate choice of maintenance methods to preserve this investment becomes
increasingly important. Therefore, this project study attempts to assess, evaluate, and present
the performance measure of road safety index for heavy road maintenance of BWHAS,
especially in problematic routs. In order to measure the performance capacity of the existing
roads, the study of the project applies the five basic road safety index characteristics
