Abstract
The D runway in the Tokyo International Airport is planned to be constructed on a reclamation area and the concrete slabs on the pier. The asphalt pavement on the slab for runway is designed with a total thickness of 20cm because it is necessary to accommodate various airport facilities in it like light devices and their pipe conduit. Since the pipe conduit of light devices is installed on the hard slab and it is embedded in comparatively upper part of the pavement, it was feared that fatigue cracks would be generated in the pavement around or on the conduit due to heavy aircraft gear loads. Therefore, authors executed experiment and FEM simulation which modeled the pipe conduit section to examine the safety for the fatigue of the pavement around or on the pipe conduit section for pavement design life. As a result of the experiment and analysis, it was confirmed the safety of the pavement for the fatigue cracking over the design period.
