A Review of PCN Determination of Airport Pavements Using FWD/HWD Test

Abstract Airport pavements are widely constructed as airport runways, taxiways, and aprons. The traffic should be considered during the design stage of before construction. To protect from negligent overload, a pavement strength rating system an aircraft load classification adopted. Under systems developed by International Civil Aviation Organization (ICAO), Aircraft Classification Number (ACN) Pavement (PCN) calculated to assess loads load-carrying capacity for unrestricted operations. With increase in air transport demand, increasing attention on continuous evaluation conditions is introduced airports across globe. can evaluated calculating value PCN continuously service cycle pavements. estimated testing response stationary dynamic loads, adopting Falling Weight Deflectometer (FWD) or Heavy (HWD) device that simulates stress generated movements. By evaluating Management System (APMS), cyclic determinations conducted support maintenance rehabilitation (M&R) decision-makers. This review summarizes methodology determining tests presented published literature. Further, highlights benefits PCNs FWD HWD field data with more precise results through mechanistic procedures.
