This research project evaluated runway pavement condition survey information in order to develop models or equations capable of predicting future pavement performance and projected life expectancy. The data was obtained from the Federal Aviation Administration FAA, and the Washington State Department of Transportation WSDOT. A previous research report analyzed the first set of Pavement Condition Index PCI data obtained from runway pavements in the tri- state area of Washington, Oregon, and Idaho. The analysis performed in this report included only runways with a second set of PCI survey data. The two primary surface categories evaluated were flexible and rigid pavements. The former includes asphalt concrete AC original surface courses, AC overlays, bituminous surface treatments BSTs, and slurry seal maintenance applications. The latter consisted only of portland cement concrete pavements. Statistical analysis in the form of regression modeling was applied to the available data and various modelsequations and graphic representations developed to predict pavement performance and projected life. The models and graphs were developed using the software packages MINITAB and Microsoft Cricket Graph, respectively.
