Airfield Pavement Condition Survey, USNAS Willow Grove, Pennsylvania.

The results of a condition survey of the airfield pavements at the U. S. Naval Air Station, Willow Grove, Pennsylvania are presented. The survey established statistically-based condition numbers weighted defect densities which were direct indicators of the condition of individual asphaltic concrete and portland cement concrete pavement facilities. Additional evaluation efforts included photographic coverage of defect types, preparation of the construction history of the station pavements, compilation of data on current aircraft traffic and aircraft types using the station, and a study of the requirements for future pavement evaluation efforts.
