USE OF PCI IN PAVEMENT MAINTENANCE MANAGEMENT SYSTEM OF ROADS A CASE STUDY ALONG SODO- AREKA ROAD

Abstract

The pavement maintenance management system (PMMS) uses a scientific approach for evaluating pavements. PCI is evaluation method is time and cost effective evaluation system. Currently Ethiopia have many infrastructure project including construction are at construction. One amongst the large problems in Ethiopia is that the failure of road infrastructure without serving design period. To resolve this problem additionally to construct new road project, proper and on time maintenance would be needed to minimize failures on road pavement. This study would point different problem on specific of road southern Ethiopia along the road of Sodo to Areka town. For PCI Quality relation standard PCI rating scale and custom PCI rating scale would be applied on suggestion for maintenance application. PCI rating range is between 0-100 looking on distress type, quantity and severity. For PCI Quality relation standard PCI rating scale and custom PCI rating scale would be applied on suggestion for maintenance application. PCI rating range is between 0-100 looking on distress type, quantity and severity. From the field work pavement condition survey was collected as 1% excellent, 12% very Good, 51% good, 29% fair, 6% poor, 0% very poor, 1% failed according to standard PCI rating scale.. The outcomes of the selected street sections that are evaluated indicates the PCI value vary (8-85). The results indicated that the majority of these roads had low PCI. Lack of efficient and proper maintenance created severely distressed pavements requiring rehabilitation. Hence, on my study ERA would be recommended to require attention on efficient maintenance i.e. equipped with modern evaluation tools, financial capabilities and trained personnel.
