SR-11 KYTC DISTRICT 10

Location: Slade, KY

Project Type: Steep Slope

Application: Slope Stabilization

Product Used: ARMORMAX

Comprised of five distinct branches Kentucky Transportation Cabinet (KYTC) Maintenance Division has a common goal of maintaining a safe, efficient, environmentally sound and fiscally responsible transportation system to ensure mobility and access and to promote economic growth for all citizens of the Commonwealth. The Roadway Maintenance Branch conducts roadway maintenance which includes the repair and stabilization of small slips and slides.

In 2020, KYTC created Master Agreements (MA) for the use of an engineered earth armoring solution (EEAS) as an alternative to rock to repair slips and slides.

In 2022, KTYC chose to use the EEAS Type 3 system setup within the MA to stabilize a slope on SR-11. ARMORMAX consisting of PYRAMAT® 75 HPTRM and nine-foot Type B2 anchors on a 4’ X 4’ spacing, met the KYTC EEAS Type 3 specifications. Permanent seeding was placed beneath the HPTRM and has begun to vegetate and blend into the natural surroundings of the state park.

The ARMORMAX system helped KYTC meet their goal of providing a safe, efficient, environmentally sound and fiscally responsible option to repair the slope while also ensuring access to the state park and economic growth in the surrounding area. Propex personnel provided on-site training and construction support to the contractor and KTYC Maintenance personnel.
