Wax and its impact on bitumen properties mean?

The English word wax was originally applied to the hair. Now the word wax application more general, such as waxes own again, and for solids, liquids that are found in nature as well as compounds that are found in the material properties such as hydrocarbon wax used to be. As well as synthetic materials that in principle, but has physical properties such as wax wax is placed in this category. In fact, the wax is insoluble in water, hardly dissolve in alcohol and if the mixture is heated with oil.

Wax is used in many industries such as candle making, polishing and colored pencils and a candle. More waxes used in the world is obtained by refining crude oil. Wax is essentially a by-product. For example, for the production of lubricant oils with high efficiency in low temperature wax is removed from the oil.
Paraffin is not suitable for the preparation of bitumen-rich crude, but the lack of asphaltene-rich crude oils makes use of naphthenic crude oil paraffin (Paraffin Naphthenic) as the base material for the production of bitumen. However, there is not accounted wax as a criterion for bitumen production. Choose a base material for the production of bitumen based on the amount of heavy wax material remaining in the distillation is performed, and the amount of wax in bitumen should not be more than 3 percent.
Wax negative impact on bitumen properties related to crystallization and melting properties of different waxes and wax have different effects on the performance of bitumen
