Hot-mix asphalts are so-called because the aggregates and binders used to produce them are heated to temperatures of the order 170 to 190°C. Conversely, cold-mix asphalts are so-called because the aggregates used are not heated. This is made possible by the use of a specialist binder called a bitumen emulsion.
