Outline of Final Research Achievements

To investigate the long-term characteristic change of stabilized soil for limited period, we developed the method for promotion of deterioration of the stabilized soil. In this deterioration method, a compulsory infiltration apparatus developed based on the equipment for concrete specimen is used. The stabilized soil can be deteriorated uniformly in relatively short term by this apparatus.
And we conducted sampling of soil stabilized in-situ 37 years ago and laboratory tests on its long-term characteristics change. As a result of the test, the relationship between deterioration depth and elapsed time consistent with the past data was obtained.
Furthermore, strength recovery of the stabilized soil, which was disturbed after several days from mixing, was investigated in detail, as well as strength reduction due to disturbance.
