Failed Road Fill Slope Stabilization


Failed Road Fill Slope Stabilization

An access road that provided mobility for a nearby intercontinental ballistic missile site experienced a shoulder failure that sloughed into an adjacent wetland area. Further regression of the failure threatened to close the road. All State and Federal jurisdictions responsible for the road sought a rapid, low-impact slope repair with a high factor of safety to permanently support the heavy missile transporter traffic and protect the wetlands below.

GeoStabilization International® rapidly and economically installed more than 200 Launched Soil Nails from above the roadway without impacting the wetlands below. The majority of the perforated nails were pressure grouted and included a central epoxy coated bar. Launched horizontal drains made of perforated fiberglass tubes were also installed to keep the naturally occurring water from building up within the slope. GeoStabilization then shotcreted the slope and stained the shotcrete to blend with the natural geology.
