In 2011 Texas drove recycled plastic made from discarded bottles into a failing US 287 slope; 5 years later, settlement was minimal and costs were 50 percent to 80 percent lower
Summary
In Texas, engineers successfully used recycled plastic pins to stabilize highway slopes affected by unstable clay soils. The experiment demonstrated significant reductions in settlement and movement in treated areas compared to untreated sections. Monitoring after installation showed minimal additional movement in reinforced sections over 5 years. The results suggest that recycled plastic pins can effectively support shallow slope failures in problematic soils.
