Abstract: The disposal of scrap tyre is a major problem in developing countries. Material recycling is adopted in order to promote safer disposal (beside conventional dump and thermal recycling). Tyre derived geomaterial (TDGM) are proposed to be used in construction of gabion type retaining wall to prevent slope failure that has been a serious geotechnical threat in many countries. The reason of choosing tyre is not only to help in reducing the stockpiling of scrap tyre generated in environmental friendly way but also to reduce the dependency of gravel as the material to filled current gabion wall. In this study, laboratory scale model of gabion wall was developed to protect soil slope. Various proportion mixture of gravel:TDGM were used to construct the gabion wall. The protected slope was subjected to an artificial rainfall of 13mm/hour. Soil movement from commencement of the test until the slope failed was recorded by using transducers. Sieve analysis, specific gravity test and compaction test were conducted beforehand upon all materials used in the study to determine basic characteristics of the materials. From this study, it is found that, due to its lightweight properties, the use of TDGM (tyre chips and tyre buffer) as unique material in gabion wall was insufficient to reduce the displacement of the gabion wall. Larger displacement of gabion wall was recorded in the case of gravel:TDGM mixture was used to fill gabion wall. TDGM need to be mixed with large amount of gravel (at least 80% by volume) to increase the self-weight of the gabion wall and increase its stability.
