Use of Emulsion
The use of bitumen emulsions began in the early part of the 20th century. Today 5% to 10% of paving-grade bitumen is used in emulsified form, but the extent of emulsion usage varies widely between countries. More than 8 million tons of emulsions are produced worldwide and the United States is the world's largest producer among the significant producers of bitumen emulsion: France, Mexico, and Brazil.
