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, KYTC chose to use the EEAS Type 3 system setup within the MA to stabilize a slope on SR-11. PROPEX® Armormax® consisting of PROPEX Pyramat® 75 HPTRM and nine-foot Type B2 anchors on a 122 cm x 122 cm (4 ft x 4 ft) 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 PROPEX 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. Solmax personnel provided on-site training and construction support to the contractor and KTYC Maintenance personnel.

Geogrid-reinforced embankment for GO Transit rail service expansion
GO Transit expanded rail service between Hamilton and Toronto, requiring a third track on a historic embankment near Sunfish Pond. A geogrid-reinforced slope with a steel sheet pile wall was implemented to meet structural and environmental requirements.
MSE walls with MIRAGRID XT for rail expansion
GO Transit used hybrid MSE walls with MIRAGRID XT geogrids to stabilize embankments on Lakeshore West Line, ensuring stability under space and load constraints.
MIRAFI geotextiles prevent subgrade failure and reduce track downtime
Canadian Pacific Railway (CP) identified track settlement issues and partnered with Solmax and Clifton Associates to implement a geosynthetic solution, reducing ballast use by 43% and completing repairs on a 72 ft section in under seven hours.
