Homogeneous reporting of Pavement Classification Number (PCN) in an Airport Pavement Management System

Abstract

PCN (Pavement Classification Number) reporting for the various airport pavement branches, such as runways, taxiways or aprons indicates the allowable weights for airplanes trafficking these areas. If the subgrade classification differ between these branches, determination of the allowable weight may include up to 4 interpolation calculations, which is neither practical for airline operators nor for airport administrators. This paper outlines a methodology for establishing homogenized PCN values to be reported for branches of an airport, based on PCN values for single points, determined from Super Heavy Weight Deflectometer (SuperHWD) testing and shows how it can be incorporated into GIS-based airport pavement management systems
