Abstract: The Federal Aviation Administration (FAA) Advisory Circular 150/5320-6C used for design of portland cement concrete (PCC) pavements for airports does not account for the site-specific values of temperature curling stresses and load transfer across joints for pavements in the kingdom of Saudi Arabia. This paper describes the formulation of a mechanistic design method for jointed PCC pavements for airports in the Kingdom based on the in situ evaluation of the apron pavement slabs of the newly built King Fahd International Airport (KFIA) in the Eastern Province. The ILLI-SLAB finite element model developed at the University of Illinois, USA, was used to analyze the in situ pavement and temperature data collected at KFIA and found to be an effective tool for analyzing the impact of a number of design variables, such as joint spacing, temperature differentials, and dowel diameter on PCC pavements structural responses. The proposed design approach employing the ILLI-SLAB model will be further calibrated and fine-tuned as the KFIA pavement performance data become available.
