Abstract
The purpose of this study is to evaluate both the failure and permeability properties of cement treated soil with tire chips using a micro-focus X-ray CT scanner. The specimens used in this study were cement treated soil both with and without tire chips. First, the effect of fraction of tire chips on the physical properties of cement treated soil is discussed based on the results of CT scanning, considering the density distribution and content of tire chips in the soil. Next, a series of unconfined compression tests was conducted with these specimens, and the failure mechanism was investigated by CT scanning the specimens during unconfined compression. A series of permeability tests using a triaxial apparatus was also performed with these specimens during the process of unconfined compression, and their permeability change was examined. Based on the results, the engineering properties of cement treated soil with tire chips were evaluated.
