Environmentally Benign Reuse of Waste Tires

该项目的目的是生成数据和分析，从而对使用回收废旧轮胎碎片加固的公路路堤进行适当的分析、材料表征和现场实施。该项目包括四个不同的阶段：(1)分析框架，(2)材料特性，(3)实地可行性论证，和(4)教育单元。分析部分致力于开发一种通用的设计方法，用于评估用轮胎碎片加固的路堤的稳定性。在拟议的分析框架中，轮胎碎片将被视为离散的加固元素。材料表征部分包括轮胎碎屑-土壤样品的全面剪切强度测试程序。本实验计划将评估轮胎碎屑土壤复合材料对不同剂量的轮胎碎屑、碎屑几何形状和土壤特性的响应。现场可行性论证包括建造一个用碎胎加固的全尺寸原型路堤，以解决拟议技术的现场可施工性和性能方面的问题。永久路堤的建设将在一家合作公司的办公场所进行，该公司将为本研究的现场部分提供物理空间、材料和建筑设备。最后，教育部分涉及汇编教育模块，将把拟议的研究纳入地球环境工程教学和正在进行的少数群体外联方案。拟议的工作旨在实施全面的材料表征、分析和现场演示组件，以建立“绿色加筋土壤设计”的基础，在该设计中，加筋夹杂不是由不可再生的聚合物材料(即土工合成材料)制成，而是由回收的废旧产品制成。

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.
