This report reviewed overseas and Australian experience in using bitumen emulsions. Increasing economic and environmental pressures have induced an increase in demand for the use of bitumen emulsions overseas. However, emulsion sprayed seals are only an alternative treatment to the use of hot cutback bitumen on low to medium trafficked roads in Australia. Bitumen emulsions use less solvent, are claimed to consume less energy, are environmentally friendly, extend the sealing season and have no problems with storage and handling.
