Deep Mixing Method was developed in Japan and Scandinavian countries in 1970s. After then, a lot of research efforts have been carried out on the strength characteristics of treated soil, interaction of treated soil and surrounding soils, developments of new binder, development new execution machine and technique, establishment of design procedure, and so on. However, long term property of treated soil has not been throughout investigated. Authors have kept two columns of in-situ quicklime treated soil underground more than 27 years. Laboratory tests were carried out on one of them at 11 and 27 years' curing periods. In this article, unconfined compressive strength, wet density, water content and calcium content on 11 and 27 years' specimen are presented to reveal that the treated soil cured for 27 years has gain threefold strength of original treated soil.
