MODIFIED HOT-MIX ASPHALT WITH ANTI-RUTTING PROPERTIES AND METHOD OF MANUFACTURING THE SAME

摘要

An hot asphalt mix with improved resistance to rutting is disclosed. The asphalt mix comprises a stabilizer comprising the mineral porcelanite and an activating agent and optionally a polymer. The asphalt mix is stable and meets performance requirements according to national standards. The stabilizer provides an improved rutting resistance of 30 - 50% relative to traditional hot asphalt mixes, and is much less expensive than polymer stabilizers. The asphalt mix is thus more stable and economical than existing asphalt mixes.
