Emulsion Bitumen
Bitumen Emulsions have being developed and exponentially increased sinned they were created in 1900. Estimated presently at 20% of the global bitumen use, bitumen emulsions are basically an O/W – Oil on Water solution – A dispersion of bitumen particles on water, stabilized with the addition of surfactants – Surface active agents – or most commonly known as emulsifiers, that will permit the bitumen to de diluted in water. They are primarily used for Tack Coats and for use between Hot Mix Asphalt layers and Prime Coats for thin hot mix surfacing layers or a chip seal pavements.
Bitumen Emulsions are divided into Two categories:
