Abstract
Two model tests were performed on tire shred fills to document the dynamic elastic material properties of tire shreds using the large centrifuge at UC Davis. The tests were considered to be “element” tests of tire shred material properties, rather than the more typical centrifuge modeling of a site profile. As these were the first tests using tire shred material on the UC Davis centrifuge, new construction and instrumentation techniques were developed. New geophysical wave sources for use with tire shreds were developed to identify reasonable material properties to use in FEM analyses. In addition to the geophysical testing for elastic material parameters, each tire shred fill was shaken with a suite of earthquake and sinusoidal motions using the servo-hydraulic shaking table mounted on the centrifuge. A two-dimensional finite element model using the elastic material parameters identified from the centrifuge tests was used to explore the effects of incorporating tire shred fills with varying geometries in bridge abutment backfills. Modal analyses were used to examine the effects of including shreds on the abutment natural frequency. Results of these preliminary analyses are mentioned briefly.
