for retaining walls andbridge abutments, lightweight fill for embankments, insulation layer for roadway base, vibrationdamping materials for rail lines, and rubberized hot mix asphalt for pavement. It also presents aroadmap of civil engineering classes that cover waste tire applications.Mechanics of MaterialsThis lecture mainly covers the physical properties of tire derived aggregates. TDA are pieces ofshredded tires that are generally between 1 inch and 12 inches in largest dimension (1). Thecommon properties of TDA affecting engineering performance are: gradation, specific gravity,absorption capacity, compressibility, resilient modulus, time dependent settlement of TDA fills,shear strength, hydraulic conductivity, and thermal
