Cherokee Asphalt Solutions LLC (CAS) is a Native American owned, Chicago-based company that provides asphalt pavement preservation, maintenance and installation solutions for airports, roadways and parking lots.


Your savings are accomplished by utilizing a proprietary pavement solution and application process that is also environmentally friendly thus allowing you to double or even triple the useful life of the surface. 

Our solution, GSB-88 (Gilsonite Sealer Binder), meets the specifications set by the Federal Aviation Administration (FAA AC 150/5370-10G, P-608) and Department of Defense (DOD UFGS 32 01 13.63.)   This environmentally-friendly and versatile emulsion enhances, seals, and extends the life of asphalt at a low cost per square yard.

It has been applied on pavements ranging from high-speed state highways to parking lots, city streets, county roads, and more than 500 military & civil airport runways - from Alaska to Florida and Maine to California. 

One application every three to five years can significantly extend the life of asphalt and help reduce global warming, acidification and toxic run-off by nearly 50% when compared to reconstruction.
