"PRESTRESSED PAVEMENT PERFORMANCE IN FOUR STATES" A PANEL REPORT

This report discusses the performance of four full scale prestressed concrete pavements built between 1971 and 1979 in different parts of the United States in various climatic areas carrying a range of traffic. The information was developed by a panel made up of representatives from each of the four States where a full scale prestressed pavement was constructed. These representatives were familiar with the design and construction. Details of construction, prestressing, and jointing are given for the projects at Dulles International Airport, Va., Hogestown, Pa., Brookhaven, Miss., and Tempe, Ariz. The panel performed a close inspection of the condition of these projects in March of 1981 and developed appropriate conclusions and recommendations after carefully considering the performance and characteristics of the four projects which have a total length of 22 lane miles. Some research needs in prestressed pavements were also identified. It was concluded that prestressed concrete has performed adequately. On the basis of its performance and economics, prestressed pavement is a viable alternate type. Some design guidelines are suggested and desirable future project characteristics are indicated.
