Tire Bales in Highway Applications: Feasibility and Properties Evaluation

There are growing interests in the utilization of recycled tire bales for civil engineering applications, triggered partly by the significant volumes of tires that could be disposed of in transportation projects. However, evaluation of tire bale properties and performance of tire bale embankments is, at least, limited. This report summarizes the benefits and shortcomings of using tire bales in civil engineering projects, as well as information collected to date on their mechanical properties. The report includes the results of eight laboratory tests on typical tire bales (most of which had never been performed prior to this study) to provide critical information on tire bale geometry, both air dry and submerged unit weights, permeability, unconfined and confined compressibility characteristics including horizontal deformations, rebound and potential expansion pressures, creep behavior, and external shear strength between two tire bales. An economic analysis comparing the estimated cost of tire bales to conventional fills is presented, supported by information on Colorado Department of Transportation costs for earth embankments. Finally, detailed recommendations for utilization and implementation of tire bales as a lightweight fill in embankments are presented.
