Abstract

A series of oedometer tests were performed on remolded or reconstituted Ariake clays. The test data can be well interpreted by a straight line in the bilogarithmic ln f∼log p plot. The suction pressure p₀ of remolded or reconstituted Ariake clays are determined by back extrapolation of the oedometer test curve to the initial void ratio e₀. The void ratio at liquid limit e_L is a powerful index of normalizing the relationships of initial void ratio e₀ and suction pressure p₀ for various remolded or reconstituted Ariake clays with different liquid limits. The normalized relationship between the normalized index e₀/e_L and suction pressure p₀ is responsible for sensitivity of one. The existing oedometer data of remolded or reconstituted soils in literature are also compiled to compare with the proposed unique relationship between e₀/e_L and p₀.
