Prestressed Pavement Rehabilitation
In 1989, a landmark pavement project was opened to traffic in Blair County, Pennsylvania, that received national attention. The pavement was a two-mile section of prestressed concrete pavement that was constructed on the northbound lanes of what is now Interstate 99. The pavement has now started to show signs of distress, including transverse cracks, longitudinal cracks, spalling, and seal failure at the armored contraction joints. In addition, there are signs of shoulder separation and some localized subgrade failure. However, the ride quality of the pavement is still very good. Due to the uniqueness of this pavement section, and the lack nationally of any other similar sections in terms of design and age, traditional rehabilitation and overlay options are not necessarily directly applicable. The objective of this project was to develop recommendations for feasible rehabilitation strategies for the prestressed concrete pavement on I-99 in Blair County. As part of the work, the expected design lives and cost-effectiveness of the strategies were evaluated.
