摘要：
The objective of this paper is to investigate the property change of compacted clayey soils for cover in the landfill subjected to moisture fluctuations and local deformation. Authors have tried to evaluate the crack behavior of compacted clayey soils due to punching loading without confining pressure. Based on the results of this study, mixing the rubber chips in the soil material was proposed as a new cover soil material. As consecutive study, conventional compacted clayey soils and compacted clayey soil with rubber chips were used for the following tests: the punching test and bending test with air compressing. At each level, the compacted clayey specimen is scanned using the X-ray computed tomography (CT) scanner and then, the density change in the specimen was visualized and evaluated quantitatively.
