Abstract
The stockpiling of scrap tires is a significant threat to our environment and has been a hot topic amongst the engineering community which has been looking for long term viable solutions to the recycling and reuse of rubber tires. This paper proposes a new method of utilizing scrap tires for applications in infrastructure protection forming part of the solution strategy. The method involves mixing scrap tire particles with soil materials and placing the mixtures around civil engineering systems, for vibration absorption. The inexpensive nature of the proposed method can be of great benefits to developing countries where there are affordability issues with employing expensive resources and state-of-the-art technology for infrastructure protection. The interaction of compacted soil with interlocking rubber components exploits the well known reinforced earth principles. This study employs conventional soil-structure interaction analysis techniques for quantifying the effectiveness of rubber-soil mixtures in terms of its ability to dissipate energy and control vibrations. While deriving closed-form analytical expressions for such heterogeneous conditions remains to be a difficult task, the potential of the proposed method has been demonstrated by numerical modeling to show its effectiveness and robustness as a means of protecting low-to-medium-rise buildings in an earthquake.
