Bitumen is a dark brown to black colour glue material majorly used in the construction of bound layers of pavements. It is treated as a hazardous material because of its higher PAH (polycyclic aromatic hydrocarbons) content and presence of hydrogen sulphide. These characteristics of conventional bitumen affect humans as well as the …Web

The average viscosity on the abscissa of Figure 1 is the viscosity average of raw crude entering and leaving the exchanger. The raw crude side pressure drop of the exchanger increases to about 200% (see Figure 2) when processing dilbit. These reductions in performance become more severe at low dilbit crude feed supply temperatures during ...Web

Bitumen is produced from the residue of a vacuum distillation tower. It is called short residue or vacuum bottom. Occasionally, the long residue or a combination of different short and long residues is also used. It should be noted that a suitable penetration for short residue or vacuum bottom is between 35-300 dmm (deci-millimeter).Web

But in fact, bitumen is used as an additive to raw materials. A layer of bitumen is sprayed on a bitumen-sealed road, and then a layer of gravel is put on top. This is done again to make a double-coat seal. In a processing facility, aggregate, bitumen, and sand are heated, dried, and mixed together to make asphalt.Web
