Accuracy of Pavement Management Predictions: A Case Study at Washington Dulles International Airport

In 1982 a Pavement Management program was undertaken on the airfield pavements at Washington Dulles International Airport to establish rate of pavement deterioration, predict remaining service life, formulate a pavement rehabilitation program and estimate rehabilitation cost. Based on three prediction models, two levels of pavement quality and the time phase for rehabilitation was predicted. The prediction models took into account the Pavement Condition Index (PCI), slab cracking and aircraft traffic. During the 25 years since the Pavement Management program, the airport has continued maintenance programs, including a several panel replacement programs and complete reconstruction of several airfield pavements. This paper describes the predictions methods and compares the time period predicted for reconstruction with the actual year the pavements were reconstructed.
