    Abstract

    Recently, a new runway designated “D-runway” was constructed at Tokyo Haneda Airport. In this project, a large amount of cement treated lightweight soils made from very soft and mildly contaminated dredged clay was used. In this paper, a seawall structure using a cement treated lightweight soil made from dredged clay is introduced and the quality control of these soils in the construction work is discussed. Two types of lightweight soils, “pneumatic mixing cement treated soil” and “air-foam treated lightweight soil,” were used as backfill in the seawall structures. Design and quality control of the lightweight soils were carried out, and the seawall structures were successfully constructed. The shear strength and bulk density of the lightweight soils placed in the sites met the required specifications in design.
