This paper proposes a structural design method of concrete pavements, which imply a non-reinforced concrete pavement, a reinforced concrete pavement, a continuously reinforced concrete pavement and concrete overlays, for airports. It should be noted that concrete pavements for airports mean runways, taxiways, aprons and so on except roads and parking lots for usual cars in the airports. The term structural design of pavements refers to the determination of the thicknesses of the subbase and the concrete slab, the joints and jointing arrangements, the reinforcements and reinforcing arrangements, and not to the design of materials in the pavement and the arrangements of runways, taxiways and aprons.
　The destermination of the thickness of the pavement is based on the basic equation for interior loading for runway slabs developed by H, M. Westergaard. For non-reinforced and reinforced concrete pavements the design methods are based on those of Portland Cement Association at Illinois in the United States, and for a continuously reinforced concrete pavement the design method is based on that of Continuously Reinforced Pavement Group at Illinois in the United States. The design method of concrete overlays conforms to that of the Corps of Engineers of the United States Army.
