In the structural design of the alternative pavement composition use is made of the APSDS (Airport Pavement Structural Design System) software package utilizing the Cumulative Damage Factor (CDF) approach. The results are compared with LEDFAA (Layered Elastic Design Federal Aviation Administration) output. A thorough analysis has been made regarding the reliability of the design, together with the material characteristics to be used and the deformation resistance of the unbound aggregate interlayer. Based on these calculations the alternative design is structurally sound and allows a planned approach towards structural maintenance, reducing the overall need as well as the costs. Although AAS did at the end choose the ‘standard’ design for the 5th runway, the proposed alternative was adopted for the reconstruction of Taxiway Alpha A8-9.
