Using shredded tires as an alternative backfill material for retaining walls is an effective method for recycling a common and abundant waste material. In this paper, the engineering properties of the shredded tire from various sources were compiled; retaining walls were designed for static and seismic conditions using the average properties following LRFD method and compared with that of conventional granular material. The performance of retaining wall backfilled with shredded tires was then investigated by applying design earthquake acceleration-time histories using advanced finite element software and compared with that of sand backfill. Results show that the shredded tire backfill significantly reduces the wall tip deflection and maximum shear force and bending moment along the wall.
