摘要：	The successful implementation in the Republic of the Philippines of a powerful and sophisticated pavement management system is discussed. This system is suitable for road network applications ranging from national strategic road networks to regional or district arterial and collector/distributor networks. The system consists of an accurate and up-to-date locational reference system for the road network; automated pavement condition data collection techniques; data management, data access, and data presentation techniques based on an easy-to-use geographic information system, which also provides menu control of data analysis processes; and a pavement investment analysis system. Particular features of the investment analysis system, based on the World Bank Highway Design and Maintenance Standards (HDM-III) package, include the abilities to (a) analyze networks of any size, by classifying network elements into pavement categories; (b) determine economic impacts of alternative maintenance strategies over the pavement life cycle, by predicting pavement deterioration under the action of maintenance strategies over the life cycle, and predicting the life-cycle cost streams that arise under each strategy; (c) include both agency costs and road user costs (i.e., vehicle operating costs and user time costs) in the economic analysis; (d) determine the optimum maintenance strategy for each pavement category under budget constraints, or average network condition standard constraints; and (e) determine an optimum distribution of budget allocation across a 3-year budget program. The HDM package has proven to be adaptable to technological environments beyond its original domain of relevance. In this project, successful performance and economic modeling of concrete pavements has been achieved, based on historical performance data. Successful implementation of a pavement management system in any road authority requires that three principal issues covering institutional impact be adequately addressed: technology impact, management commitment, and follow-through from planning to delivery.
