The U.S. Department of Transportation Federal Aviation Administration (FAA) has developed Standards for Specifying Construction of Airports. The most recent version was published in 2009. The entire 522 page document is available here. Two of the standards (P-630 and P-631) address refined coal tar-based sealcoat (RTS). Standard P-609 addresses asphalt-based emulsions. These three standards are available at the links below.
