In the Tokyo International Airport (Haneda Airport), a new runway named "D-runway" was planned and constructed from March 2007 to October 2010. Because some part of the D-runway is located in a river mouth, a hybrid structure consisting of piled pier and reclamation fill was adopted. In the reclamation section, not only the ground improvement technologies (SD, CPD and CDM) but also the new developed construction materials (pneumatic mixing cement treated soil and air-foam treated lightweight soil) were utilized. This technical report describes the outline of the project, ground investigation, and design of the D-runway structure, from a geotechnical point of view.
