Use of the processed used tires in embankment construction is becoming an accepted way of beneficially recycling scrap tires due to shortages of natural mineral resources and increasing waste disposal costs. Using these used tires in construction requires an awareness of the properties and the limitations associated with their use. The main objective of this paper is to assess the different processing techniques on the mechanical properties of used tires-sand mixtures to improve the engineering properties of the available soil. In the first part, a literature study on the mechanical properties of the processed used tires such as tire shreds, tire chips, tire buffings and their mixtures with sand are summarized. In the second part, large-scale direct shear tests are performed to evaluate shear strength of tire crumb-sand mixtures where information is not readily available in the literature. The test results with tire crumb were compared with the other processed used tire-sand mixtures. Sand-used tire mixtures have higher shear strength than that of the sand alone and the shear strength parameters depend on the processing conditions of used tires. Three factors are found to significantly affect the mechanical properties: normal stress, processing techniques, and the used tire content.
由于自然资源短缺和废物处理成本不断增加，将废旧轮胎进行加工并用于路堤建设正成为一种有益的废旧轮胎回收方式。在建筑中使用这些废旧轮胎需要了解与使用相关的特性和限制。本文的主要目的是评估不同加工技术对废旧轮胎-砂混合物力学性能的影响，以改善现有土壤的工程性能。在第一部分，对已加工废旧轮胎（如轮胎碎片、轮胎屑、轮胎磨屑等）及其与砂混合的力学性能进行了文献综述。在第二部分，进行了大型直剪试验，以评估轮胎碎屑-砂混合物的抗剪强度，因为文献中没有现成的信息。试验结果与其他已加工废旧轮胎-砂混合物进行了比较。轮胎碎屑与砂的混合物具有比单独砂更高的抗剪强度，且抗剪强度参数取决于废旧轮胎的加工条件。研究发现有三个因素显著影响力学性能：法向应力、加工技术和废旧轮胎含量。
