“…Furthermore, as illustrated in Eqs. (9,10), the permissible vertical compressive stress and permissible vertical compressive strain at the top of the subgrade were investigated by Kirk [45] and PIARC [46] respectively to correlate the failure condition of the subgrade layer to loading repetitions.…”

“…The design methods of road and airport pavements are developed using mechanistic methods such as layered elastic method and finite element modeling. Based on the relationship between transportation repetitions and the strains observed by the actual performance of full-scale pavements under full-scale loading, the pavement life can be estimated to meet the requirements of airport design [9].…”

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

“…Chai et al [39] performed an airfield pavement design analysis at a major airport comparing FAARFIELD and APSDS. The pavement structure thicknesses from the two codes were approximately the same when the subgrade CBR was greater than 10.…”

“…However, in cases where the CBR was less than 10, FAARFIELD calculated a greater pavement structure thickness. Chai et al [39] proposed that the difference in the required pavement thickness is due to how the two codes calculate the maximum subgrade strain; FAARFIELD uses all of the aircraft wheels whereas APSDS uses a single wheel group loading. This discrepancy occurring when using the FAARFIELD 1.3 version has been addressed in the recent FAARFIELD 1.4 version with a change in how certain multi-gear aircraft are analyzed.…”
