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 eL 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/eL 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/eL and p0.
