Description

High bearing force and cost effective construction methods can be possible, if used tires are recycled in original form. But such reusing methods are scarcely conducted. In this paper, we make laminar bodies which are packed by granular materials in the hollow center of the tires, using original tires. We validated the characteristics of the laminar bodies thorough compression tests. The experimental results reveal that laminar bodies have high strength especially in pre-stress conditions. In terms of land formation, we propose the easier and earlier construction method. These construction methods can reuse large amount of used tires and contribute to the environment conservation.
