Abstract
To meet the increasing demand for air transportation, Ministry of Transport has carried out an offshore development project at the Tokyo International Airport (Haneda Airport). Since the airport is constructed on extremely soft ground reclaimed by dredged sludge, it is predicted that the consolidation settlement will continue after opening the new airport. Extensive observation of the differential Settlement has been carried out during construction of the project. The results of the statistical analyses of settlement show that the damage to the airport pavements due to differential settlement for 10 years will not be serious. It is possible, however, that partial repair work to improve the grade of pavement surfaces may be required.
