Tire derived aggregate (TDA) is a recycled fill material produced by cutting scrap tires into pieces ranging in size from 12 to 305 mm. For the last two decades, TDA has been successfully used in various projects such as embankments, bridge abutments, subgrade insulation for roads, vibration mitigation for rail lines, and landfill daily cover. The material properties of TDA are necessary for the planning and design of such projects; however, there is limited information available, especially for large-size TDA (maximum particle size >= 75 mm). Large-size TDA is typically used as lightweight fill material for embankments, foundations, and retaining walls. In this paper, the material properties of large-size TDA, as collected from published sources and recently completed material tests, are presented and discussed. These properties include unit weight, shear strength, compressibility, and lateral earth pressure coefficient. In addition, several civil engineering projects are discussed and compared to highlight the use of TDA in state-of-the-art applications.
