Slope failure repair using tyre bales at Interstate Highway 30, Tarrant County, Texas, USA

The remediation of soil cut slope instability in Texas has traditionally been achieved using conventional methods. However, in early 2002 an alternative approach was taken to achieve the remediation of a failed slope using tyre bales, which are blocks of compressed whole post-consumer tyres. This paper describes the construction of the repair, the comparative retrospective analysis that was carried out to determine the likely performance of such slope repairs, and visual observations made around two years after construction. Specific lessons are drawn from the experience gained from this work.
