Abstract: Nigeria road pavement is subjected to have low road density of 23km/m2 of the pave land area and justification for this material stress, functional disability and loss of cohesion. In Ebonyi state there is needs to assess the impact of failed road pavement on economic growth and social stability of the state. Most of the state urban roads failed because of many vehicles passing in definite section of the road per unit time at any suitable period, subjecting the paved areas into physically disintegration of crystalline aggregated material informed of ruttings, pothole, raveling and cracks and some deteriorate or decomposed in a large number of cement aggregate into organic matter causing chemical separations and moisture attack on the paved area by attacking the fabric bond of the binding pavement. The aim of this research is to analyze roads pavement failures for effective cost management. The research design comprised extensive literature. This research was to facilitate the measurement of variables on affected areas causing surface depression and surface deterioration on large number of aggregated crystalline material from rehabilitation of the respective road projects. The research was design to measure stress types, stress values, stress seventy and stress density derive from affected paved area. The data collected were presented in tables, percentage, and pie chart and analyzed with multiple regressions. The findings will establish the state of stress over strain will be sustainable for road pavement in urban areas. The model implies based on the data collected the cause of stress values in urban roads increase by 0.284 (28.4%) were trigger increase in road rehabilitation, repairs and remedial works by 0.77, 0.31 and 0.60 and which were ascertain the level of cost implementation for effective life cycle costing on urban roads in the state.
