| Popis: | The objective of this study was to evaluate the influences of both tyre buffings and lime in clay. California Bearing Ratio (CBR) and Unconfined Compression (UC) tests were conducted on the mixtures prepared with tyre buffings and lime. Tyre buffings and lime contents in the mixtures were 0%, 5%, 10%, and 15%, and 0%, 2%, 4%, and 6% by dry weight of the specimens, respectively. The response of the specimens was investigated with the inclusion of tyre buffings only, lime only, and tyre buffings and lime together. Test results revealed that addition of tyre buffings only reduces the CBR value of clay, while addition of lime only increases the CBR value of clay. Addition of a small amount of lime to the clay with tyre buffings increases the CBR values of the specimens, and thereby may cause a substantial decrease in design thickness of a highway pavement. Similar results were also obtained by the UC tests. Consequently, this research suggests to use both tyre buffings and lime as an alternative method to imp... |
