International Slurry Surfacing Association (ISSA)

The International Slurry Surfacing Association (ISSA) is a U.S.-based non-profit industry association founded in 1963 that promotes slurry seal, micro surfacing, chip seals, and related surface treatments. ISSA organizes meetings and technical events, such as the Slurry Systems Workshop (SSWS), maintains technical resources like manuals and training, and lists upcoming events on its website. Its primary focus is pavement maintenance and preservation, which are closely related to city public works functions like street maintenance. While specialized in slurry/micro surfacing, it is highly relevant for pavement maintenance and street operations within public works.
