Decades of research by former DOD and FAA subject matter experts and consulting engineers have found GSB treatments more rigorously evaluated than other treatments and showing superior performance over decades.

*P-608 and P-608-R were the only FAA Surface Treatment Specifications applied on all airfield pavements with limitations.
