Environmentally Benign Reuse of Waste Tires

该项目的目的是生成数据和分析，从而进行适当的分析，材料表征和现场实施的高速公路加固，使用回收的废轮胎碎片。 该项目包括四个不同的阶段：（1）分析框架，（ii）材料特性，（iii）现场可行性演示，（iv）教育模块。 分析部分追求一个通用的desighn方法的发展，用于轮胎碎片增强水泥稳定性评价。 轮胎碎片将被视为离散的加强元素，在拟议的分析框架。 材料表征部分涉及轮胎碎片-土壤样本的综合剪切强度测试程序。 该实验方案将评估轮胎碎片土壤复合材料的反应，以不同剂量的轮胎碎片，碎片的几何形状，和土壤特性。 实地可行性论证涉及建造一个用碎轮胎加固的全尺寸原型路堤，以解决拟议技术的实地可施工性和性能问题。 永久路堤的加固将在一家合作公司的场地内进行，该公司将为本研究的现场部分提供物理空间、材料和施工设备。 最后，教育部分涉及的教育模块，将拟议的研究纳入地质环境工程教学和正在进行的外展少数民族计划的汇编。 拟议的努力寻求实施全面的材料表征，分析和现场演示组件，以建立一个“绿色加筋土设计”的基础，其中的钢筋夹杂物不是由不可再生的聚合物材料（即土工合成），但从回收的废物产品。

The purpose of this project is the generation of data and analysis leading to proper analysis, material characterization, and field implementation of highway embankments reinforced using shreds from recycled waste tires. The project includes four distinct phases: (1) analytical framework, (ii) material characterization, (iii) field feasibility demonstration, and (iv) educational modules. The analytical component pursues the development of a generic desighn methodology for stability evaluation of embankments reinforced with tire shreds. Tire shreds will be treated as discrete reinforcing elements in the proposed analytical framework. The material characterization component involves a comprehensive shear strength testing program of tire shreds-soil specimens. This experimental program will evaluate the response of tire shredsoil composites to varying dosages of tire shreds, shred geometries, and soil characteristics. the field feasibility demonstration involves construction of a full-scale prototype embankment reinforced with shredded tires in order to address field constructibility and performance aspects of the proposed technology. Contruction of the permanent embankment will take place in the premises of a collaborating company that will provide the physical space, materials, and construction equipment for the field component of this research. Finally, the educational component involves the compilation of educational modules that will integrate the proposed research into geoenvironmental engineering instruction and into ongoing outreach minority programs. The proposed effort seeks implementation of comprehensive material characterization, analysis, and field demonstration components in order to establish the basis for a "green reinforced soil design" in which the reinforcement inclusions are not made from nonrenewable polymeric materials (i.e. geosynthesis) but from recycled waste products.
