Advancement of Pavement strength to prevent frequent failure. Models of Rural Roads

Abstract

Ethiopia has wasted billions of dollars on replacing its national highways that have prematurely deteriorated (Jovanovic, 2014). Big, expensive road systems have been poorly maintained while being more regularly used and damaged than originally anticipated. As old pavements collapse and as new ones last longer than expected, the degradation of maintained roadways will increase if this carelessness is allowed to continue. That's why the roads in Ethiopia are in such a sorry state. One-fourth of the annual infrastructure spending goes on roads. Fewer resources are allocated to preserving the nation's paved roads, which slows the progress of the industry as a whole. Document analysis, participant observation, and a questionnaire survey were all used to compile the data for this study. For this review, we obtained the Pavement Repair Road Annual Reports for the preceding three years from the ERA's Central District Region. In a similar vein, data was gathered from road repair contractors and consultants, as well as road users in a variety of settings. The visual inspection of five sites revealed that the maintained roads were being used by overloaded trucks, that the pavements were old, that severe weather had been observed, that the drainages were poor, that the construction quality was poor and that the construction materials were substandard, that the maintenance management system was poor, and that all of these problems had contributed to the deterioration of the pavements.
