What is the difference between hot asphalt and cold asphalt?
Hot mix asphalt is is heated for application, which thins the material. Remember those steaming metal buckets you used to see on industrial rooftops? Cold asphalt is liquified with something else besides heat. There are two kinds: Emulsified asphalt is mixed with water and an emulsifying agent. Think of it like salad dressing that does not separate in the bottle. The other kind is called Cutback asphalt and is mixed with a petroleum solvent such as naptha, gasoline, or kerosene. They both are liquids at ambient temperature when applied; then the solvent or water evaporates, leaving the asphalt behind. Look up at asphaltinstitute.org
