Bitumen Penetration |
Description: |
Bitumen is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleums and in some natural deposits. Until the 20th century, the term asphaltum was also used.It is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement haltuamongst chemists regarding its structure).One writer states that although a "considerable amount of work has been done on the composition of asphalt, it is exceedingly difficult to separate individual hydrocarbon in pure form", and "it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large". In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the U.S., the product is often called bitumen. Natural deposits terminology also sometimes uses the word bitumen, such as at the La Brea Tar Pits. The primary use of asphalt is in road construction, where it is used as the glue or binder for the aggregate particles. Grades: Bitumen 40/50 Bitumen 60/70 Bitumen 80/100 Bitumen 100/120
