Asphalt concrete - Wikipedia

Asphalt concrete is 100% recyclable and is the most widely reused construction material in the world. Very little asphalt concrete — less than 1 percent, according to a survey by the Federal Highway Administration and the National Asphalt Pavement Association conducted annually since 2009 — is actually disposed of in landfills.
