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.

该项目的目的是生成数据和分析，从而导致使用回收废物轮胎中的切碎的高速公路路堤的正确分析，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，（ii）材料表征，（iii）现场可行性演示和（iv）教育模块。 分析成分追求开发通用的Desighn方法论，以评估用轮胎丝增强的路堤的稳定性评估。 轮胎丝将被视为拟议的分析框架中的离散增强元件。 材料表征成分涉及轮胎丝 - 土壤标本的全面剪切强度测试程序。 该实验计划将评估轮胎切碎的复合材料对不同剂量的轮胎切碎，切碎的几何形状和土壤特性的响应。 现场可行性演示涉及建造一个用切碎轮胎加固的全尺度原型路堤，以解决拟议技术的现场构造性和性能方面。 永久性路堤的概况将在一家合作公司的场所进行，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，教育部分涉及教育模块的汇编，这些模块将将拟议的研究纳入地理环境工程教学和正在进行的外展少数群体计划中。 拟议的努力旨在实施全面的材料表征，分析和现场演示组件，以建立“绿色增强土壤设计”的基础，在该基础上，并不是由不可再生的聚合物材料（即地质合成）进行增强夹杂物，而是由重生废物的废物浪费的废物。产品。
