| dc.description.abstract | Highway engineers are changing their attention from the construction of new roads to maintenance of the existing network. Pavement maintenance is set activities for ensuring safe, serviceable and sustainable road network till the end of the design life of pavements. Improper maintenance, on the other hand, has the tendency to adversely affect pavement performances. Declined performance of pavements results in disruption of the traffic stream and for motorists it reduces vehicle performances. The dynamics of road deterioration have much to do with the road maintenance problem. Maintenance deferment has huge implication in vehicle operation and on national economy. Delayed maintenance ultimately results in reconstruction which will be very expensive for a country like Ethiopia which is promisingly developing at the moment. In this regard, the adverse impact of maintenance deferment is the focus of this research. This paper characterizes poor maintenance in terms of delayed application of the required maintenance activities and in accurate forecasting of traffic flow. For studying these effects, a principal arterial road along the east-west corridor of Addis Ababa was chosen. The road network starts from Megenagna passes through Meskel Square and terminates at Torhayloch. This network covers about 8.2 kilometer length. Adequate and regular maintenance requires securing of sufficient funding before repairs and maintenance become an urgent issue. Economic decisions are needed in a highway system to account for the total cost of transportation on the road section: the discounted life-cycle cost of constructing and maintaining the roads and far larger cost of operating vehicles on these roads. This research assesses the economic impact that comes as a result of poor maintenance activities. The research uses Highway Development and Management model to measure the impact quantitatively. The model integrates road network conditions, vehicle characteristics and maintenance programs and finally generates a summary of the economic indicators. The result reveals; in relation to timely maintenance, delayed maintenance brings NPV of Birr -194.79 Economic Impact of Poor Pavement Maintenance in the City of Addis Ababa iv | P a g e million and in relation to accurate traffic demand, improper forecasting of traffic flow demand brings NPV of Birr -193.7 million. In conclusion, it is no wonder that proper maintenance action has the capability to extend the service life of road infrastructures. However, if such maintenance neglect continues, it will not only reduce service levels and accessibility but also hugely increase the whole lifetime cost of the transport infrastructure. This eventually incurs negative impact in overall economic growth of the country. Key Words: Pavement Performance, Poor Pavement Maintenance, Economic indicators, Economic impact | en_US |
