• Description:
  The report discusses the design and 10-year performance evaluations of Expanded Polystyrene (EPS) Geofoam embankment constructed for the I-15 Reconstruction Project in Salt Lake City, Utah between 1998 and 2002. It contains methods to evaluate the allowable stress in the EPS from live (traffic) and dead loads. It also contains numerical modeling of the pressure and deformation data collected as part of the long-term monitoring effort. Based on these data, this report demonstrates that the design criteria in regards to creep and settlement were met. In addition, the seismic stability of free-standing EPS embankments is evaluated and recommendations are made regarding how to improve their seismic performance. A simplified design methodology is presented to evaluate the embankment for interlayer seismic sliding.
