bitumen

Chemically bitumen components are divided into two groups of Hydrocarbure , Asphaltine , and Maltin. There is 5-30% Asphaltin in bitumen which causes the hardness of the bitumen. Maltin is made of grease and resin.
By regulating operational variables such as the temperature of reactor, residence time in the reactor, and the ratio of air to feed it will be possible to produce different grades of bitumen for various consumptions such as road and industrial types. Moreover adding some proper additives allows us to produce modified bitumen like Polymer Modified Bitumen (PMB) which is highly resistant in heavy traffic and bad climatic conditions. Another bitumen product is bitumen emulsion which is gradually substituting cutbacks for its environmental privileges as well as energy consumption savings.
