The quicklime pile method has been adopted to improve weak soil foundations, especially those consisting of high moisture cohesive soil. When the method is applied to peat foundation which has organic soil with 1000-1500 % moisture content, it is necessary that the quicklime maintains its hydraulic characteristic as a stabilizing material without losing its water absorbing and expanding effects. In the present study, a new hydraulic quicklime consisting of 71.3% CaO, 13.9% SiO_2, 6.0% R_2O_3, 2.5% MgO etc., was used instead of a usual quicklime consisting of 82.9% CaO, 7.8% SiO_2, 2.5% R_2O_3, 1.1% MgO etc., and the improvement of peat foundation by this new hydraulic quicklime was examined mainly by plate loading tests, N value, chemical durability etc.. The results were satisfactory.
