RCRA Hazardous Waste (US, 40 CFR 261)
Clean asphalt pavement milling is not a federal hazardous waste under RCRA. It is recycled for road base or recovered as aggregate. Tar-bound material (pre-1980 roads) may contain hazardous coal tar.
Also searched as: bituminous mixtures, road planings, tarmac, asphalt millings
No federal hazardous waste code
Asphalt does not carry a federal RCRA hazardous waste code. It is regulated as solid waste under state and local rules, and specifics depend on your state environmental agency.
Not being federally hazardous does not mean it has no value — clean asphalt is often a recovered commodity with active buyers.
RCRA classifies waste by source, process, and characteristics — not just material. Pick the row that matches how your asphalt arises; each coded row links to the full waste code definition under 40 CFR Part 261.
Clean bituminous pavement (post-1980)
