ILLUSTRATION OF PAVEMENT MANAGEMENT: FROM DATA INVENTORY TO PRIORITY ANALYSIS

A typical case history of a pavement management implementation project is summarized. The project covered a major part of the highway system of the province of Prince Edward Island (PEI) and was undertaken in conjunction with the Federal-Provincial Atlantic Provinces Highway Strengthening Improvement Agreement. An extensive field inventory was performed on approximately 500 km of PEI's Trans Canada and major-arterial road networks. These field tests provided the basis for detailed analysis to determine the pavement-improvement needs for the portion of the road network considered over a 10-year programming period. A program of pavement-improvement priorities over the programming period was then determined through economic analysis and an optimization of projects, improvement strategies, and project timing. The effect of budget level was then analyzed by comparing the expected average network serviceability profiles over the programming period at the specified budget level with the case of zero capital budget for both the Trans Canada and major-arterial networks. PEI is one of the first areas in North America to successfully adopt such a comprehensive pavement management system. This indicates that the concepts of pavement management, which have been developed during the last decade, are now being put into practice. (Author)
