| Outline of Final Research Achievements |
In order to clarify the mechanical properties of lime-stabilized soil with waste material (short-fiber made from polyester), a series of laboratory tests at different mixture rate of the short-fiber were carried out. The experiments involve consolidated undrained triaxial compression (CUb) test, consolidated drained triaxial compression (CD) test. The following conclusions are obtained from this study: (1) The shear strength of the lime-stabilized soil increases slightly by mixing appropriate amount of the short-fiber. But if the amount of the short-fiber is putting into the soil too much, the strength of the soil decreases inversely. (2) On the other hand, mixing the short-fiber into the lime-stabilized soil has demonstrated a very high effect against strain-softening of the soil material.
